importance of critical thinking in our education system

Developing Critical Thinking

• Posted January 10, 2018

In a time where deliberately false information is continually introduced into public discourse, and quickly spread through social media shares and likes, it is more important than ever for young people to develop their critical thinking. That skill, says Georgetown professor William T. Gormley, consists of three elements: a capacity to spot weakness in other arguments, a passion for good evidence, and a capacity to reflect on your own views and values with an eye to possibly change them. But are educators making the development of these skills a priority?

"Some teachers embrace critical thinking pedagogy with enthusiasm and they make it a high priority in their classrooms; other teachers do not," says Gormley, author of the recent Harvard Education Press release The Critical Advantage: Developing Critical Thinking Skills in School . "So if you are to assess the extent of critical-thinking instruction in U.S. classrooms, you’d find some very wide variations." Which is unfortunate, he says, since developing critical-thinking skills is vital not only to students' readiness for college and career, but to their civic readiness, as well.

"It's important to recognize that critical thinking is not just something that takes place in the classroom or in the workplace, it's something that takes place — and should take place — in our daily lives," says Gormley.

In this edition of the Harvard EdCast, Gormley looks at the value of teaching critical thinking, and explores how it can be an important solution to some of the problems that we face, including "fake news."

Integrating Critical Thinking Into the Classroom

(This is the second post in a three-part series. You can see Part One here .)

The new question-of-the-week is:

What is critical thinking and how can we integrate it into the classroom?

Part One ‘s guests were Dara Laws Savage, Patrick Brown, Meg Riordan, Ph.D., and Dr. PJ Caposey. Dara, Patrick, and Meg were also guests on my 10-minute BAM! Radio Show . You can also find a list of, and links to, previous shows here.

Today, Dr. Kulvarn Atwal, Elena Quagliarello, Dr. Donna Wilson, and Diane Dahl share their recommendations.

‘Learning Conversations’

Dr. Kulvarn Atwal is currently the executive head teacher of two large primary schools in the London borough of Redbridge. Dr. Atwal is the author of The Thinking School: Developing a Dynamic Learning Community , published by John Catt Educational. Follow him on Twitter @Thinkingschool2 :

In many classrooms I visit, students’ primary focus is on what they are expected to do and how it will be measured. It seems that we are becoming successful at producing students who are able to jump through hoops and pass tests. But are we producing children that are positive about teaching and learning and can think critically and creatively? Consider your classroom environment and the extent to which you employ strategies that develop students’ critical-thinking skills and their self-esteem as learners.

Development of self-esteem

One of the most significant factors that impacts students’ engagement and achievement in learning in your classroom is their self-esteem. In this context, self-esteem can be viewed to be the difference between how they perceive themselves as a learner (perceived self) and what they consider to be the ideal learner (ideal self). This ideal self may reflect the child that is associated or seen to be the smartest in the class. Your aim must be to raise students’ self-esteem. To do this, you have to demonstrate that effort, not ability, leads to success. Your language and interactions in the classroom, therefore, have to be aspirational—that if children persist with something, they will achieve.

Use of evaluative praise

Ensure that when you are praising students, you are making explicit links to a child’s critical thinking and/or development. This will enable them to build their understanding of what factors are supporting them in their learning. For example, often when we give feedback to students, we may simply say, “Well done” or “Good answer.” However, are the students actually aware of what they did well or what was good about their answer? Make sure you make explicit what the student has done well and where that links to prior learning. How do you value students’ critical thinking—do you praise their thinking and demonstrate how it helps them improve their learning?

Learning conversations to encourage deeper thinking

We often feel as teachers that we have to provide feedback to every students’ response, but this can limit children’s thinking. Encourage students in your class to engage in learning conversations with each other. Give as many opportunities as possible to students to build on the responses of others. Facilitate chains of dialogue by inviting students to give feedback to each other. The teacher’s role is, therefore, to facilitate this dialogue and select each individual student to give feedback to others. It may also mean that you do not always need to respond at all to a student’s answer.

Teacher modelling own thinking

We cannot expect students to develop critical-thinking skills if we aren’t modeling those thinking skills for them. Share your creativity, imagination, and thinking skills with the students and you will nurture creative, imaginative critical thinkers. Model the language you want students to learn and think about. Share what you feel about the learning activities your students are participating in as well as the thinking you are engaging in. Your own thinking and learning will add to the discussions in the classroom and encourage students to share their own thinking.

Metacognitive questioning

Consider the extent to which your questioning encourages students to think about their thinking, and therefore, learn about learning! Through asking metacognitive questions, you will enable your students to have a better understanding of the learning process, as well as their own self-reflections as learners. Example questions may include:

• Why did you choose to do it that way?
• When you find something tricky, what helps you?
• How do you know when you have really learned something?

‘Adventures of Discovery’

Elena Quagliarello is the senior editor of education for Scholastic News , a current events magazine for students in grades 3–6. She graduated from Rutgers University, where she studied English and earned her master’s degree in elementary education. She is a certified K–12 teacher and previously taught middle school English/language arts for five years:

Critical thinking blasts through the surface level of a topic. It reaches beyond the who and the what and launches students on a learning journey that ultimately unlocks a deeper level of understanding. Teaching students how to think critically helps them turn information into knowledge and knowledge into wisdom. In the classroom, critical thinking teaches students how to ask and answer the questions needed to read the world. Whether it’s a story, news article, photo, video, advertisement, or another form of media, students can use the following critical-thinking strategies to dig beyond the surface and uncover a wealth of knowledge.

A Layered Learning Approach

Begin by having students read a story, article, or analyze a piece of media. Then have them excavate and explore its various layers of meaning. First, ask students to think about the literal meaning of what they just read. For example, if students read an article about the desegregation of public schools during the 1950s, they should be able to answer questions such as: Who was involved? What happened? Where did it happen? Which details are important? This is the first layer of critical thinking: reading comprehension. Do students understand the passage at its most basic level?

Ask the Tough Questions

The next layer delves deeper and starts to uncover the author’s purpose and craft. Teach students to ask the tough questions: What information is included? What or who is left out? How does word choice influence the reader? What perspective is represented? What values or people are marginalized? These questions force students to critically analyze the choices behind the final product. In today’s age of fast-paced, easily accessible information, it is essential to teach students how to critically examine the information they consume. The goal is to equip students with the mindset to ask these questions on their own.

Strike Gold

The deepest layer of critical thinking comes from having students take a step back to think about the big picture. This level of thinking is no longer focused on the text itself but rather its real-world implications. Students explore questions such as: Why does this matter? What lesson have I learned? How can this lesson be applied to other situations? Students truly engage in critical thinking when they are able to reflect on their thinking and apply their knowledge to a new situation. This step has the power to transform knowledge into wisdom.

Adventures of Discovery

There are vast ways to spark critical thinking in the classroom. Here are a few other ideas:

• Critical Expressionism: In this expanded response to reading from a critical stance, students are encouraged to respond through forms of artistic interpretations, dramatizations, singing, sketching, designing projects, or other multimodal responses. For example, students might read an article and then create a podcast about it or read a story and then act it out.
• Transmediations: This activity requires students to take an article or story and transform it into something new. For example, they might turn a news article into a cartoon or turn a story into a poem. Alternatively, students may rewrite a story by changing some of its elements, such as the setting or time period.
• Words Into Action: In this type of activity, students are encouraged to take action and bring about change. Students might read an article about endangered orangutans and the effects of habitat loss caused by deforestation and be inspired to check the labels on products for palm oil. They might then write a letter asking companies how they make sure the palm oil they use doesn’t hurt rain forests.
• Socratic Seminars: In this student-led discussion strategy, students pose thought-provoking questions to each other about a topic. They listen closely to each other’s comments and think critically about different perspectives.
• Classroom Debates: Aside from sparking a lively conversation, classroom debates naturally embed critical-thinking skills by asking students to formulate and support their own opinions and consider and respond to opposing viewpoints.

Critical thinking has the power to launch students on unforgettable learning experiences while helping them develop new habits of thought, reflection, and inquiry. Developing these skills prepares students to examine issues of power and promote transformative change in the world around them.

‘Quote Analysis’

Dr. Donna Wilson is a psychologist and the author of 20 books, including Developing Growth Mindsets , Teaching Students to Drive Their Brains , and Five Big Ideas for Effective Teaching (2 nd Edition). She is an international speaker who has worked in Asia, the Middle East, Australia, Europe, Jamaica, and throughout the U.S. and Canada. Dr. Wilson can be reached at [email protected] ; visit her website at www.brainsmart.org .

Diane Dahl has been a teacher for 13 years, having taught grades 2-4 throughout her career. Mrs. Dahl currently teaches 3rd and 4th grade GT-ELAR/SS in Lovejoy ISD in Fairview, Texas. Follow her on Twitter at @DahlD, and visit her website at www.fortheloveofteaching.net :

A growing body of research over the past several decades indicates that teaching students how to be better thinkers is a great way to support them to be more successful at school and beyond. In the book, Teaching Students to Drive Their Brains , Dr. Wilson shares research and many motivational strategies, activities, and lesson ideas that assist students to think at higher levels. Five key strategies from the book are as follows:

• Facilitate conversation about why it is important to think critically at school and in other contexts of life. Ideally, every student will have a contribution to make to the discussion over time.
• Begin teaching thinking skills early in the school year and as a daily part of class.
• As this instruction begins, introduce students to the concept of brain plasticity and how their brilliant brains change during thinking and learning. This can be highly motivational for students who do not yet believe they are good thinkers!
• Explicitly teach students how to use the thinking skills.
• Facilitate student understanding of how the thinking skills they are learning relate to their lives at school and in other contexts.

Below are two lessons that support critical thinking, which can be defined as the objective analysis and evaluation of an issue in order to form a judgment.

Mrs. Dahl prepares her 3rd and 4th grade classes for a year of critical thinking using quote analysis .

During Native American studies, her 4 th grade analyzes a Tuscarora quote: “Man has responsibility, not power.” Since students already know how the Native Americans’ land had been stolen, it doesn’t take much for them to make the logical leaps. Critical-thought prompts take their thinking even deeper, especially at the beginning of the year when many need scaffolding. Some prompts include:

• … from the point of view of the Native Americans?
• … from the point of view of the settlers?
• How do you think your life might change over time as a result?
• Can you relate this quote to anything else in history?

Analyzing a topic from occupational points of view is an incredibly powerful critical-thinking tool. After learning about the Mexican-American War, Mrs. Dahl’s students worked in groups to choose an occupation with which to analyze the war. The chosen occupations were: anthropologist, mathematician, historian, archaeologist, cartographer, and economist. Then each individual within each group chose a different critical-thinking skill to focus on. Finally, they worked together to decide how their occupation would view the war using each skill.

For example, here is what each student in the economist group wrote:

• When U.S.A. invaded Mexico for land and won, Mexico ended up losing income from the settlements of Jose de Escandon. The U.S.A. thought that they were gaining possible tradable land, while Mexico thought that they were losing precious land and resources.
• Whenever Texas joined the states, their GDP skyrocketed. Then they went to war and spent money on supplies. When the war was resolving, Texas sold some of their land to New Mexico for $10 million. This allowed Texas to pay off their debt to the U.S., improving their relationship.
• A detail that converged into the Mexican-American War was that Mexico and the U.S. disagreed on the Texas border. With the resulting treaty, Texas ended up gaining more land and economic resources.
• Texas gained land from Mexico since both countries disagreed on borders. Texas sold land to New Mexico, which made Texas more economically structured and allowed them to pay off their debt.

This was the first time that students had ever used the occupations technique. Mrs. Dahl was astonished at how many times the kids used these critical skills in other areas moving forward.

Integrating 21st century skills into education systems: From rhetoric to reality

February 14, 2019

This is the third post in a series about  education systems alignment in teaching, learning, and assessing 21st century skills .

What does it mean to be a successful learner or graduate in today’s world? While in years past, a solid acquisition of the “three Rs” (reading, writing, and arithmetic) and mastery in the core academic subjects may have been the measure of attainment, the world of the 21 st century requires a radically different orientation. To participate effectively in the increasingly complex societies and globalized economy that characterize today’s world, students need to think critically, communicate effectively, collaborate with diverse peers, solve complex problems, adopt a global mindset, and engage with information and communications technologies, to name but just a few requirements. The new report from Brookings, “ Education system alignment for 21st century skills: Focus on assessment ,” illuminates this imperative in depth.

Recognizing that traditional education systems have generally not been preparing learners to face such challenges, the global education community has increasingly talked about and mobilized in favor of the changes required. This has resulted in a suite of initiatives and research around the broad area of “21st century skills,” which culminated most notably with the adoption of Sustainable Development Goal 4 and the Education 2030 agenda, including Target 4.7, which commits countries to ensure that learners acquire knowledge and skills in areas such as sustainable development, human rights, gender equality, global citizenship, and others.

In this landscape, Global Partnership for Education (GPE) has a core mandate of improving equity and learning by strengthening education systems. GPE supports developing countries, many of which are affected by fragility and conflict, to develop and implement robust education sector plans. Depending on the country, GPE implementation grants support a broad range of activities including teacher training, textbook provision, interventions to promote girls’ education, incentives for marginalized groups, the strengthening of data and learning assessment systems, early childhood education, and many other areas.

This work is buttressed by thematic work at the global level, including in the area of learning assessment. The strengthening of learning assessment systems is a strategic priority for GPE because of its relevance to both improving learning outcomes and ensuring effective and efficient education systems, which are two of the three key goals of the GPE strategic plan for the 2016-2020 period . The work on learning assessment includes the Assessment for Learning (A4L) initiative, which aims to strengthen learning assessment systems and to promote a holistic measurement of learning.

Under A4L, we are undertaking a landscape review on the measurement of 21st century skills, using a definition derived from Binkley et. al . and Scoular and Care :

“21st century skills are tools that can be universally applied to enhance ways of thinking, learning, working and living in the world. The skills include critical thinking/reasoning, creativity/creative thinking, problem solving, metacognition, collaboration, communication and global citizenship. 21st century skills also include literacies such as reading literacy, writing literacy, numeracy, information literacy, ICT [information and communications technologies] digital literacy, communication and can be described broadly as learning domains.”

Using this lens, the landscape review examines the research literature, the efforts of GPE partners that have been active in this space, and data collected from a sample of countries in sub-Saharan Africa and Asia in regard to the assessment of these skills. These research efforts were led by Brookings and coordinated by the UNESCO offices in Dakar and Bangkok. As another important piece of this work, we are also taking stock of the latest education sector plans and implementation grants of these same countries (nine in sub-Saharan Africa and six in Asia), to explore the extent to which the integration of 21st century skills is reflected in sector plans and, vitally, in their implementation.

Though the work is in progress, the initial findings provide food for thought. Reflecting the conclusions of the new report by Brookings, as well as its earlier breadth of work on skills mapping, a large majority of these 15 countries note ambitious objectives related to 21st century skills in their education sector plans, particularly in their vision or mission statements and/or statements of policy priorities. “Skills” such as creativity and innovation, critical thinking, problem-solving, decisionmaking, life and career skills, citizenship, personal and social responsibility, and information and communications technology literacy were strongly featured, as opposed to areas such as collaboration, communication, information literacy, and metacognition.

However, when we look at the planned interventions noted in these sector plans, there is not a strong indication that countries plan to operationalize their intentions to promote 21st century skills. Not surprisingly then, when we look at their implementation grants, which are one of the financing instruments through which education sector plans are implemented, only two of the 15 grants examined include activities aimed at promoting 21st century skills among their program components. Because the GPE model mandates that national governments determine the program components and allocation of resources for these within their grant, the bottom line seems to echo the findings of the Brookings report: vision and aspiration are rife, but action is scarce.

While the sample of countries studied in this exercise is small (and other countries’ education sector plans and grants may well include integration of 21st century skills), it’s the disconnect between the 15 countries’ policy orientation around these skills and their implementation that is telling. Why this gap? Why, if countries espouse the importance of 21st century skills in their sector plans, do they not concretely move to addressing them in their implementation? The reasons for this may be manifold, but the challenges highlighted by the Brookings report in terms of incorporating a 21 st century learning agenda in education systems are indeed telling. As a field, we still have much work to do to understand the nature of these skills, to develop learning progressions for them, and to design appropriate and authentic assessment of them. In other words, it may be that countries have difficulty in imagining how to move from rhetoric to reality.

However, in another perspective, there may be a challenge associated with how countries (and the broader education community) perceive 21st century skills in general. In contexts of limited resources, crowded curricula, inadequately trained teachers, fragility, weak governance, and other challenges that are characteristic of GPE partner countries, there is sometimes an unfortunate tendency to view 21st century skills and the “basics” as a tradeoff. In such settings, there can be a perception that 21st century skills are the concern of more advanced or higher-income countries. It is thus no wonder that, in the words of the Brookings report, “a global mobilization of efforts to respond to the 21CS [21st century skills] shift is non-existent, and individual countries struggle alone to plan the shift.”

This suggests that those who are committed to a holistic view of education have much work to do in terms of research, sharing of experience, capacity building, and advocacy around the potential and need for all countries, regardless of context, to move in this direction. The Brookings report makes a very valuable contribution in this regard. GPE’s landscape review, which will be published this spring, will inform how the partnership thinks about and approaches 21st century skills in its work and will thereby provide a complementary perspective.

The State of Critical Thinking 2020

November 2020, introduction.

In 2018, the Reboot Foundation released a first-of-its-kind survey looking at the public’s attitudes toward critical thinking and critical thinking education. The report found that critical thinking skills are highly valued, but not taught or practiced as much as might be hoped for in schools or in public life. 

The survey suggested that, despite recognizing the importance of critical thinking, when it came to critical thinking practices—like seeking out multiple sources of information and engaging others with opposing views—many people’s habits were lacking. Significant numbers of respondents reported relying on inadequate sources of information, making decisions without doing enough research, and avoiding those with conflicting viewpoints.

In late 2019, the Foundation conducted a follow up survey in order to see how the landscape may have shifted. Without question, the stakes surrounding better reasoning have increased. The COVID-19 pandemic requires deeper interpretive and analytical skills. For instance, when it comes to news about a possible vaccine, people need to assess how it was developed in order to judge whether it will actually work. 

Misinformation, from both foreign and domestic sources, continues to proliferate online and, perhaps most disturbingly, surrounding the COVID-19 health crisis. Meanwhile, political polarization has deepened and become more personal . At the same time, there’s both a growing awareness and divide over issues of racism and inequality. If that wasn’t enough, changes to the journalism industry have weakened local civic life and incentivized clickbait, and sensationalized and siloed content. 

Part of the problem is that much of our public discourse takes place online, where cognitive biases can become amplified, and where groupthink and filter bubbles proliferate. Meanwhile, face-to-face conversations—which can dissolve misunderstandings and help us recognize the shared humanity of those we disagree with—go missing. 

Critical thinking is, of course, not a cure-all, but a lack of critical thinking skills across the population exacerbates all these problems. More than ever, we need skills and practice in managing our emotions, stepping back from quick-trigger evaluations and decisions, and over-relying on biased or false sources of information. 

To keep apprised of the public’s view of critical thinking, the Reboot Foundation conducted its second annual survey in late 2019. Unfortunately, the COVID-19 pandemic forced a delay in the release of the results. Nevertheless, this most recent survey dug deeper than our 2018 poll, and looked especially into how the public understands the state of critical thinking education. For the first time, our team also surveyed teachers on their views on teaching critical thinking.

General Findings

Support for critical thinking skills remains high, but there is also clearly skepticism that individuals are getting the help they need to acquire improved reasoning skills. A very high majority of people surveyed (94 percent) believe that critical thinking is “extremely” or “very important.” But they generally (86 percent) find those skills lacking in the public at large. Indeed, 60 percent of the respondents reported not having studied critical thinking in school. And only about 55 percent reported that their critical thinking skills had improved since high school, with almost a quarter reporting that those skills had deteriorated. 

There is also broad support among the public and teachers for critical thinking education, both at the K-12 and collegiate levels. For example, 90 percent think courses covering critical thinking should be required in K-12. 

Many respondents (43 percent) also encouragingly identified early childhood as the best age to develop critical thinking skills. This was a big increase from our previous survey (just 20 percent) and is consistent with the general consensus among social scientists and psychologists. 

There are worrisome trends—and promising signs—in critical thinking habits and daily practices. In particular, individuals still don’t do enough to engage people with whom they disagree. 

Given the deficits in critical thinking acquisition during school, we would hope that respondents’ critical thinking skills continued to improve after they’ve left school. But only about 55 percent reported that their critical thinking skills had improved since high school, with almost a quarter reporting that their skills had actually deteriorated since then. 

Questions about respondents’ critical thinking habits brought out some encouraging information. People reported using more than one source of information when making a decision at a high rate (around 77 percent said they did this “always” or “often”) and giving reasons for their opinions (85 percent). These numbers were, in general, higher than in our previous survey (see “Comparing Survey Results” below).

In other areas of critical thinking, responses were more mixed. Almost half of respondents, for example, reported only “sometimes,” “rarely,” or “never” seeking out people with different opinions to engage in discussion. Many also reported only “sometimes,” “rarely,” or “never” planning where (35 percent) or how (36 percent) to get information on a given topic. 

These factors are tied closely together. Critical thinking skills have been challenged and devalued at many different levels of society. There is, therefore, no simple fix. Simply cleansing the internet of misinformation, for example, would not suddenly make us better thinkers. Improving critical thinking across society will take a many-pronged effort.

Comparing Survey Results  

Several interesting details emerged in the comparison of results from this survey to our 2018 poll. First, a word of caution: there were some demographic differences in the respondents between the two surveys. This survey skewed a bit older: the average age was 47, as opposed to 36.5. In addition, more females responded this time: 57 percent versus 46 percent.

That said, there was a great deal of consistency between the surveys on participants’ general views of critical thinking. Belief in the importance of critical thinking remains high (94 percent versus 96 percent), as does belief that these skills are generally lacking in society at large. Blame, moreover, was spread to many of the same culprits. Slightly more participants blamed technology this time (29 versus 27 percent), while slightly fewer blamed the education system (22 versus 26 percent). 

Respondents were also generally agreed on the importance of teaching critical thinking at all levels. Ninety-five percent thought critical thinking courses should be required at the K-12 level (slightly up from 92 percent); and 91 percent thought they should be required in college (slightly up from 90 percent). (These questions were framed slightly differently from year to year, which could have contributed to the small increases.)

One significant change came over the question of when it is appropriate to start developing critical thinking skills. In our first survey, less than 20 percent of respondents said that early childhood was the ideal time to develop critical thinking skills. This time, 43 percent of respondents did so. As discussed below, this is an encouraging development since research indicates that children become capable of learning how to think critically at a young age. 

In one potentially discouraging difference between the two surveys, our most recent survey saw more respondents indicate that they did less critical thinking since high school (18 percent versus just 4 percent). But similar numbers of respondents indicated their critical thinking skills had deteriorated since high school (23 percent versus 21 percent).

Finally, encouraging points of comparison emerged in responses to questions about particular critical thinking activities. Our most recent survey saw a slight uptick in the number of respondents reporting engagement in activities like collaborating with others, planning on where to get information, seeking out the opinions of those they disagree with, keeping an open mind, and verifying information. (See Appendix 1: Data Tables.)

These results could reflect genuine differences from 2018, in either actual activity or respondents’ sense of the importance of these activities. But demographic differences in age and gender could also be responsible. 

There is reason to believe, however, that demographic differences are not the main factor, since there is no evident correlation between gender and responses in either survey. Meanwhile, in our most recent survey older respondents reported doing these activities less frequently . Since this survey skewed older, it might have been anticipated that respondents would report doing these activities less. But the opposite is the case.

Findings From Teacher Survey

Teachers generally agree with general survey respondents about the importance of critical thinking. Ninety-four percent regard critical thinking as “extremely” or “very important.” 

Teachers, like general survey participants, also share concerns that young people aren’t acquiring the critical thinking skills they need. They worry, in particular, about the impact of technology on their students’ critical thinking skills. In response to a question about how their school’s administration can help them teach critical thinking education more effectively, some teachers said updated technology (along with new textbooks and other materials) would help, but others thought laptops, tablets, and smartphones were inhibiting students’ critical thinking development. 

This is an important point to clarify if we are to better integrate critical thinking into K-12 education. Research strongly suggests that critical thinking skills are best acquired in combination with basic facts in a particular subject area. The idea that critical thinking is a skill that can be effectively taught in isolation from basic facts is mistaken. 

Another common misconception reflected in the teacher survey involves critical thinking and achievement. Although a majority of teachers (52 percent) thought all students benefited from critical thinking instruction, a significant percentage (35) said it primarily benefited high-ability students. 

At Reboot, we believe that all students are capable of critical thinking and will benefit from critical thinking instruction. Critical thinking is, after all, just a refinement of everyday thinking, decision-making, and problem-solving. These are skills all students must have. The key is instilling in our young people both the habits and subject-area knowledge needed to facilitate the improvement and refinement of these skills.

Teachers need more support when it comes to critical thinking instruction. In the survey, educators repeatedly mentioned a lack of resources and updated professional development. In response to a question about how administrators could help teachers teach critical thinking more effectively, one teacher asked for “better tools and materials for teaching us how to teach these things.” 

Others wanted more training, asking directly for additional support in terms of resources and professional training. One educator put it bluntly: “Provide extra professional development to give resources and training on how to do this in multiple disciplines.” 

Media literacy is still not being taught as widely as it should be. Forty-four percent of teachers reported that media literacy courses are not offered at their schools, with just 31 percent reporting required media literacy courses. 

This is despite the fact that teachers, in their open responses, recognized the importance of media literacy, with some suggesting it should be a graduation requirement. Many organizations and some governments, notably   Finland’s , have recognized the media literacy deficit and taken action to address it, but the U.S. education system has been slow to act.

Thinking skills have been valuable in all places and at all times. But with the recent upheavals in communication, information, and media, particularly around the COVID-19 crisis, such skills are perhaps more important than ever. 

Part of the issue is that the production of information has been democratized—no longer vetted by gatekeepers but generated by anyone who has an internet connection and something to say. This has undoubtedly had positive effects, as events and voices come to light that might have previously not emerged. The recording of George Floyd’s killing is one such example. But, at the same time, finding and verifying good information has become much more difficult. 

Technological changes have also put financial pressures on so-called “legacy media” like newspapers and television stations, leading to sometimes precipitous drops in quality, less rigorous fact-checking (in the original sense of the term), and the blending of news reports and opinion pieces. The success of internet articles and videos is too often measured by clicks instead of quality. A stable business model for high-quality public interest journalism remains lacking. And, as biased information and propaganda fills gaps left by shrinking newsrooms, polarization worsens. (1)

Traditional and social media both play into our biases and needs for in-group approval. Online platforms have proven ideal venues for misinformation and manipulation. And distractions abound, damaging attention spans and the quality of debate.

Many hold this digital upheaval at least partially responsible for recent political upheavals around the world. Our media consumption habits increasingly reinforce biases and previously held beliefs, and expose us to only the worst and most inflammatory views from the other side. Demagogues and the simple, emotion-driven ideas they advance thrive in this environment of confusion, isolation, and sensationalism. 

It’s not only our public discourse that suffers. Some studies have suggested that digital media may be partially responsible for rising rates of depression and other mood disorders among the young. (2)

Coping with this fast-paced, distraction-filled world in a healthy and productive manner requires better thinking and better habits of mind, but the online world itself tends to encourage the opposite. This is not to suggest our collective thinking skills were pristine before the internet came along, only that the internet presents challenges to our thinking that we have not seen before and have not yet proven able to meet. 

There are some positive signs, with more attention and resources being devoted to neglected areas of education like civics and media literacy ; organizations trying to address internet-fueled polarization and extremism; and online tools being developed to counter fake news and flawed information. 

But we also need to support the development of more general reasoning skills and habits: in other words, “critical thinking.” 

Critical thinking has long been a staple of K-12 and college education, theoretically, at least, if not always in practice. But the concept can easily appear vague and merely rhetorical without definite ideas and practices attached to it. 

When, for example, is the best age to teach critical thinking? What activities are appropriate? Should basic knowledge be acquired at the same time as critical thinking skills, or separately? Some of these questions remain difficult to answer, but research and practice have gone far in addressing others.

Part of the goal of our survey was to compare general attitudes about critical thinking education—both in the teaching profession and the general public—to what the best and most recent research suggests. If there is to be progress in the development of critical thinking skills across society, it requires not just learning how best to teach critical thinking but diffusing that knowledge widely, especially to parents and educators. 

The surveys were distributed through Amazon’s MTurk Prime service. 

For the general survey, respondents answered a series of questions about critical thinking, followed by a section that asked respondents to estimate how often they do certain things, such as consult more than one source when searching for information. The questions in the “personal habit” section appeared in a randomized order to reduce question ordering effects. Demographic questions appeared at the end of the survey.

For the teacher survey, respondents were all part of a teacher panel created by MTurk Prime. They also answered a series of questions on critical thinking, especially focused on the role of critical thinking in their classrooms. After that, respondents answered a series of questions about how they teach—these questions were also randomized to reduce question ordering effects. Finally, we asked questions related to the role of media literacy in their classrooms.

To maintain consistency with the prior survey and to explore relationships across time, many of the questions remained the same from 2018. In some cases, following best practices in questionnaire design , we revamped questions to improve clarity and increase the validity and reliability of the responses.

For all surveys, only completed responses coming from IP addresses located in the U.S. were analyzed. 1152 respondents completed the general survey; 499 teachers completed the teacher survey.

Detailed Findings and Discussion

As summarized above, the survey produced a number of noteworthy findings. One central theme that emerged was a general pessimism about the state of critical thinking and uncertainty about how to improve it. That is, despite the near-universal acknowledgment of the importance of critical thinking, respondents generally think society at large is doing a bad job of cultivating critical thinking skills. Respondents were, moreover, divided about what needs to be done.

Almost all the people surveyed (94 percent) believe that critical thinking is “extremely” or “very important.” But they generally (86 percent) find those skills lacking in the public at large. These numbers don’t come as a huge surprise—and they echo the 2018 results—but they do suggest broad public support for initiatives that advance critical thinking skills, both inside and outside of schools.

Respondents also reported deficits in their own critical thinking training and practices. They tended not to think critical thinking had been a point of emphasis in their own education, with a substantial majority of over 63 percent reporting that they had not studied critical thinking in school. Around 20 percent said their schools had provided no background in critical thinking at all, and another 20 percent said the background in critical thinking they gained from school was only slight.

There were significant differences among age groups in these self-reports. Around half of respondents in both the 0-19 and 20-39 age groups reported having studied critical thinking in school. Those numbers dwindled among older groups, bottoming out at 11 percent among 80 to 100-year-olds.

This result is likely in part due to the increased popularity of the phrase “critical thinking”: prior generations may have spent a substantial amount of time on reasoning skills without it coming under the same vocabulary. The young are also closer to school-age, of course, so may simply have sharper memories of critical thinking activities. But the differences in responses might also reflect genuine differences in education. 

In any case it’s clear that, even recently, many—if not most—students come out of school feeling as if they have not learned how to think critically, despite the fact that there is broad consensus on the importance of these skills. Only around 25 percent of respondents reported receiving an “extremely” or “very” strong background in critical thinking from their schools. 

There are a number of potential causes—technology, social norms, misguided educational priorities—but perhaps the most salient is that, as cognitive scientist Tim van Gelder puts it, “critical thinking is hard.” As van Gelder emphasizes, we don’t naturally think reasonably and rationally; instead we tend to rely on narrative, emotion, and intuition—what feels right. (3)   Teaching students to think critically requires much more guidance and practice, throughout the curriculum, than is currently being provided. 

There is broad support among the public and among teachers for critical thinking education, both at the K-12 and collegiate levels. 

Around 90 percent of respondents in the general public said that courses covering critical thinking should be required at the K-12 level, while 94 percent of teachers said critical thinking is important.

And schools usually echo this sentiment as well, citing the phrase “critical thinking” frequently in curricula and other materials. But it remains unclear if, in practice, critical thinking is really the priority it’s made out to be rhetorically.

One problem is a tendency to think critical thinking and reasoning are too complex for younger students to tackle. But research has shown that children start reasoning logically at a very young age. (4)   Critical thinking through activities like open-ended dialogue, weighing opposing perspectives, and backing up opinions with reasoning can have a positive effect even at the K-5 level. For example, philosophy for kids courses have shown some  positive effects on students’ reading and math skills (gains were even more substantial for disadvantaged students). (5)

Our survey respondents generally agreed that critical thinking skills should be taught from an early age. Forty-three percent favored beginning critical thinking instruction during early childhood (another 27 percent favored beginning at ages 6-12). This was more than a twofold increase over the results from 2018’s survey, in which just 20 percent thought it was best to begin instruction in critical thinking before the age of 6. This increase is encouraging since it’s consistent with recent research that understands critical thinking as part of general cognitive development that starts even before children enter school. (6)

Many teachers likewise support critical thinking instruction beginning at a young age. In the open response, for example, one wrote, “Critical thinking should be explicitly taught in earlier grades than late middle school and high school.” 

Another wrote: “By the time students get to high school they should have this skill [critical thinking] well tuned. The pressure to meet standards earlier and earlier makes it harder to teach basic skills like critical thinking.” 

Many teachers (55 percent) also thought the emphasis on standardized testing has made it more difficult to incorporate critical thinking instruction in the classroom. For example, one wrote, “Standardized testing has created an environment of quantitative results that don’t always represent qualitative gains.” 

Moreover, a plurality of teachers (25 percent) believe that state standardized tests do not assess critical thinking skills well at all, while just 13 percent believe they assess critical thinking skills extremely well. Teachers generally (52 percent) believe that their own tests do a better job of measuring critical thinking skills.

The survey also found some worrisome trends—as well as some promising signs—in how people evaluated their own critical thinking skills and daily practices. In particular, individuals don’t do enough to engage people with whom they disagree. 

Given the deficits in critical thinking acquisition during school, it might be hoped that respondents’ critical thinking skills continued to improve after they’ve left school. But only about 55 percent reported that their critical thinking skills had improved since high school, with almost a quarter reporting that their skills had actually deteriorated since then. 

This is especially alarming because thinking critically, unlike say learning about calculus or the Russian Revolution, is generally thought to be a lifelong endeavour. We are supposed to become better with age and experience. Research into adult education suggests that it’s never too late to make gains in critical thinking.  (7)

Questions about respondents’ critical thinking habits brought out more detailed information. Some of these responses were encouraging. People reported using more than one source of information when making a decision at a high rate (around 77 percent said they did this “always” or “often”), giving reason for their opinions (85 percent), supporting their decisions with information (84 percent), and listening to the ideas of those they disagree with (81 percent). Participants generally reported engaging in more critical thinking activities this time than in our initial survey. (See “Comparing Survey Results” above.)

It’s difficult to totally identify the drivers of these figures. After all, all humans are prone to overestimating the amount and quality of reasoning we do when we come to decisions, solve problems, or research information. But, at the very least, these numbers indicate that people acknowledge that these various critical thinking habits are admirable goals to shoot for. 

At the same time and unsurprisingly, these results suggest a reluctance to engage in the more demanding aspects of critical thinking: difficult or unpleasant tasks like seriously considering the possibility that our opponents might be right or thinking carefully about how to approach information-gathering before we engage in it.

Weaknesses in these areas of critical thinking can be especially easily exploited by emotionalized, oversimplified, and sensationalistic news and rhetoric. If people jump in to information-gathering without even a rough plan or method in mind they’re more likely to get swept up by clickbait or worse. 

The current media environment requires a mindful and deliberate approach if it is to be navigated successfully. And one’s own opinions will remain under-nuanced, reactive, and prone to groupthink if they’re influenced by the extreme opinions and caricatures that are often found online and on television instead of by engagement with well-reasoned and well-intentioned perspectives.

Poor media consumption habits can have a distorting effect on our political perceptions, especially. Recent research, for example, has identified wildly inaccurate stereotypes among the general public about the composition of political parties. One study found that “people think that 32% of Democrats are LGBT (versus 6% in reality) and 38% of Republicans earn over $250,000 per year (vs. 2% in reality).” (8) The study also suggested, alarmingly, that “those who pay the most attention to political media may […] also [be] the likeliest to possess the most misinformation about party composition.” (9)

The public is worried about the impact of technology on the acquisition of critical thinking skills. They also blamed deficits in critical thinking on changing societal norms and the education system.

Modern technology was the most cited reason for a lack of critical thinking skills among the general public, with “changing societal norms” coming in a close second. Over 200 respondents also cited the educational system (see chart below).

A number of the teachers also mentioned potential drawbacks of technology in the classroom environment. For example, in the open response portion of the survey, which allowed teachers to voice general concerns, one teacher wrote: “Get rid of the laptops and tablets and bring back pencil and paper because the students aren’t learning anything using technology.” Another said: “Personal Electronic devices need to be banned in schools.”

In our own work at the Reboot Foundation, the research team found evidence of negative correlations between technology use at schools and achievement. For example, an analysis of data from the National Assessment of Education Progress (NAEP) showed that fourth graders using tablets “in all or almost all” classes performed significantly worse (the equivalent of a full grade level) than their peers who didn’t use them. 

Another recent study the foundation supported also suggested students benefited from using pencil and paper as opposed to technology to do math homework. The Organization for Economic Cooperation and Development found similar results a few years ago in their international study of 15-year-olds and computer usage. (10)

There is a great deal the field still doesn’t know about the effects of different kinds of technology on different kinds of learning. But a growing stock of research suggests that schools should be cautious about introducing technology into classrooms and the lives of students in general, especially young students. (11)

It would also be a mistake to slip into simple Luddism though. Technology, obviously, provides benefits as well—making education more accessible, reducing costs, helping teachers to fine-tune instruction to student needs, to name a few. During the coronavirus crisis, moreover, educators have had no choice but to rely and hopefully help improve these tools.

Still, too often in the past schools have turn ed to technology without properly weighing the costs against the benefits, and without determining whether technology is truly needed or effective. A recent RAND Corporation paper, for example, discussed programs “seeking to implement personalized learning” but without “clearly defined evidence-based models to adopt.” (12)

The Reboot survey suggests that members of the public as well as teachers generally share these concerns, both about educational technology specifically and about the general impact of technology on student learning.

While teachers support critical thinking instruction, they are divided about how to teach it, and some educators have beliefs about critical thinking instruction that conflict with established research.

One central question in the research about how to best instill critical thinking skills in students is whether critical thinking should be taught in conjunction with basic facts and knowledge or separated from it. 

Teachers were split on this question, with 41 percent thinking students should engage in critical thinking practice while learning basic facts, while 42 percent thought students should learn basic facts first then engage in critical thinking practice. A further 16 percent believe that basic facts and critical thinking should be taught separately. (However, only about 13 percent of teachers surveyed say that content knowledge either doesn’t matter at all or only matters slightly for critical thinking skills.)

The view that knowledge and critical thinking skills can and should be taught separately is mistaken. There is a common view that since information is so widely accessible today, learning basic facts is no longer important. According to this view, it’s only cognitive skills that matter. But the two cannot be so neatly divorced as is often assumed. (13)

Research in cognitive science strongly suggests that critical thinking is not the type of skill that can be divorced from content and applied generically to all kinds of different contexts. As cognitive scientist Daniel T. Willingham argues, “The ability to think critically […] depends on domain knowledge and practice.” (14)

This means students need to practice critical thinking in many different kinds of contexts throughout the curriculum as they acquire the background knowledge needed to reason in a given context. There are of course general skills and habits that can be extrapolated from these various kinds of practice, but it is very unlikely that critical thinking can be taught as a skill divorced from content. “It […] makes no sense,” Willingham writes, “to try to teach critical thinking devoid of factual content.”

This doesn’t necessarily mean standalone critical thinking courses should be rejected. Students can still gain a lot from learning about formal logic, for example, and from learning about metacognition and the best research practices. But these standalone courses or programs should include acquisition of basic factual knowledge as well, and the skills and habits learned in them must be applied and reinforced in other courses and contexts.

Students, moreover, should be reminded that being “critical” is an empty slogan unless they have the requisite factual knowledge to make a cogent argument in a given domain. They need background knowledge to be able to seek out evidence from relevant sources, to develop reliable and nuanced interpretations of information, and to back the arguments they want to make with evidence.

Reboot also asked teachers about which students they thought benefited from critical thinking instruction. A majority (52 percent) thought it benefits all students, but 35 percent said (with the remaining 13 percent thinking it primarily benefits lower-ability students). 

The view that critical thinking instruction is only effective for higher achieving students is another common misconception. Everyone is capable of critical thinking, and even, to a certain extent, engages in critical thinking on their own. The key is for students to develop metacognitive habits and subject-area knowledge so that they can apply critical thought in the right contexts and in the right way. Educators should not assume that lower-achieving students will not benefit from critical thinking instruction. 

Teachers need more support when it comes to critical thinking instruction, though at least some teacher training and professional development programs do seem to help.

In the survey, educators repeatedly mentioned a lack of resources and updated professional development. In response to a question about how administrators could help teachers teach critical thinking more effectively, one teacher asked for “better tools and materials for teaching us how to teach these things.” 

Another said, “Provide opportunities for teachers to collaborate and cross train across subject areas, as well as providing professional development that is not dry or outdated.” Another characteristic comment: “Provide extra professional development to give resources and training on how to do this in multiple disciplines.”

Overall teachers were relatively satisfied that teacher training and professional development programs were helping them teach critical thinking. Forty-six percent said that their teacher training helped them a lot or a great deal, while 50 percent said professional development programs help them a lot or a great deal.

But other teachers reported burdensome administrative tasks and guidelines were getting in the way of teacher autonomy and critical thinking instruction. For example, one teacher wrote, “Earlier in my career I had much more freedom to incorporate instruction of critical thinking into my lessons.”

Media literacy is still not being taught as widely as it should be. 

In our survey, teachers rightly recognized that media literacy is closely bound up with critical thinking. One said, “I believe that media literacy goes hand in hand with critical thinking skills and should be a requirement […] especially due to the increase in use of technology among our youth.” Another offered that “media literacy should be a graduation requirement like economics or government.”

But schools, at least judging by teachers’ responses in the survey, have been slow in prioritizing media literacy. More than 44 percent reported that media literacy courses are not offered at their schools, and just around 30 percent reported that media literacy courses are required. That said, the majority of teachers did report teaching typical media literacy skills occasionally in their classes. 

For example, over 60 percent said that, in at least one class, they “teach students how to distinguish legitimate from illegitimate sources,” and over two-thirds said they “teach students how to find reliable sources.” (15)

Despite the assumption sometimes made that young people (“digital natives”) must be adept navigators of the internet, recent studies have found that students have trouble evaluating the information they consume online. They have problems recognizing bias and misinformation, distinguishing between advertising and legitimate journalism, and verifying information using credible sources. 

Our age is one in which unreliable information proliferates; nefarious interests use the internet to influence public opinion; and social media encourages groupthink, emotional thinking, and pile-on. New skills and training are required to navigate this environment. Our schools must adapt. 

This means generating and implementing specific interventions that help students learn to identify markers of misinformation and develop healthy information-gathering habits. The Reboot Foundation’s own research suggests that even quick and immediate interventions can have a positive impact. But it also means instilling students with life-long critical thinking habits and skills which they’ll be able to apply to an ever-changing media landscape. 

Despite its importance, which is widely acknowledged by the general public, critical thinking remains a somewhat vague and poorly understood concept. Most people realize that it is of vital importance to individual success and educational attainment, as well as to civic life in a liberal democracy. And most seem to realize that 21st-century challenges and changes make acquiring critical thinking skills of even more urgent importance. But when it comes to instilling them in children and developing them in adults, we are, in many ways, still at square one. 

Over the course of the last few decades, K-12 educators have been urged to teach critical thinking, but they have been given conflicting and inconsistent advice on how to do it. There remains a lack of proven resources for them to rely on, a lack of administrative support—and sometimes even a lack of a clear sense of what exactly critical thinking is. Perhaps most importantly, teachers lack the time and freedom within the curriculum to teach these skills.

But there have been a number of insights from cognitive science and other disciplines that suggest a way forward. Perhaps the most important is that critical thinking cannot be understood as a skill on par with learning a musical instrument or a foreign language. It is more complicated than those kinds of skills, involving cognitive development in a number of different areas and integrated with general knowledge learned in other subject areas. Critical thinking courses and interventions that ignore this basic fact may produce some gains, but they will not give students the tools to develop their thinking more broadly and apply critical thought to the world outside of school.

College and continuing education deserve attention too. It should be considered a red flag that only 55 percent of respondents didn’t think they’d made any strides in critical thinking skills since high school. Colleges have long been moving away from a traditional liberal arts curriculum . The critical thinking skills acquired across those disciplines have likely suffered as a result. 

In recent years, we’ve seen smart people who should know better time and again exhibit poor judgment online. It is important to remind each other of the importance of stepping back, managing emotions, engaging with others charitably, and seriously considering the possibility that we are wrong. This is especially important when we are searching for information online, an environment that can easily discourage these intellectual virtues. Ramping up media literacy—for both adults and young people—will be a vital part of the solution.

But, ultimately, critical thinking, which touches on so many different aspects of personal and civic life, must be fostered in a multitude of different ways and different domains. A secure, prosperous, and civil future may, quite literally, depend on it.

THE IMPORTANCE OF CRITICAL THINKING IN EDUCATION

Being a student in 2021 is quite different from being one is 2011. In a span of 10 years, the world of education has witnessed a sea change. As the world keeps facing new challenges, especially due to COVID-19, younger generations, and the education system they are a part of, has also become dynamic. However, there are certain foundations to any education system that has stood the test of time. One key element that has always been stressed upon and practiced by educators in the liberal education spectrum is imparting Critical Thinking skills.

Enhancing a student’s critical thinking skills is particularly essential in a liberal education model, which believes in teaching students how to think and not what to think.

Here are some of the reasons why students need critical thinking skills in today’s age-

Enhancing creativity and curiosity:

A student who is encouraged to be a critical thinker invariably develops a sense of curiosity of happenings around him/her. A strong and genuine sense of curiosity leads to students wanting to analyse and assimilate information and events. In the process, they form their own informed ideas, mostly out-of-the-box ones, that in turn improves their creativity. Creativity is a skill that all critical thinkers will dally with in their professional and personal life. In the process of finding answers in a logical and rational manner, they will usually be able to get their creative juices flowing.

Promoting self-assertion and self-reflection:

Critical thinking is essentially self-disciplined, self-monitored, and self-corrective thinking. When one thinks critically, it is done is a self-directed manner. There is an internalization of the issue at hand and a deep understanding of it in an objective fashion. Critical thinking is at the forefront of learning, as it aids a student reflect and understand their points of views. This skill helps a student figure out how to make sense of the world, based on personal observation and understanding. It makes learners self-assertive and confident as they know that the outcome is the result of a thought process that yields results. Students also gain confidence and the ability to learn from mistakes both of which are crucial in their personal and professional lives.

Boosting career prospects:

Critical thinking is not confined to the classroom. In the aftermath of COVID-19, the new economy places a lot of demand on a flexible workforce and employee’s ability to analyse information from various sources and come up with ingenuous solutions towards the same. An employee with strong critical thinking skills will be valued in a fast-changing workplace.

Nurturing problem-solvers and innovators:

One of the by-products of critical thinking skills is the ability to analyse and look at problems in a creative and constructive method. Critical thinkers are invariably good problem solvers. A good critical thinker will be able to separate facts from opinions and fiction and examine the issue from all angles before making rational decisions towards solving a problem. They will also be able to produce bias free solutions to problems, a fact that is crucial to note in the employment arena. As universal challenges like global warming, pollution, pandemics, continue to plague the world, youngsters of today – who will become the leaders of tomorrow – will be expected to take the mantle of finding effective solutions. Critical thinkers will engineer creative and lasting solutions.

Fostering allied life skills:

Critical thinking fosters allied life skills such as organisational skills, planning, open-mindedness, communication skills among others. Being a life skill by itself, critical thinking enables you to take on challenges in the personal and professional world with ease. It encourages confidence and independence, thereby shaping successful lives. As a critical thinker, one will learn from their mistakes, thereby notching up their productivity in all spheres of life.

As education takes different forms in a world hit by a pandemic, it is extremely crucial for students to possess skills like critical thinking, that will prepare them for tomorrow. After all, children of today are the leaders of tomorrow. Thinking critically boost creativity and enhance the way we use and manage our time and critical thinking not only describes the ability to think in accordance with the rules of logic and probability, but also the ability to apply these skills to real-life problems, which are not content-independent. . Critical thinking can provide you with a more insightful understanding of yourself. It will offer you an opportunity to be objective, less emotional, and more open-minded as you appreciate others’ views and opinions. By thinking ahead, you will gain the confidence to present fresh perspectives and new insights into burden some concerns.

Critical thinking occurs when students are analyzing, evaluating, interpreting, or synthesizing information and applying creative thought to form an argument, solve a problem, or reach a conclusion. The aim of Critical Thinking is to promote independent thinking, personal autonomy and reasoned judgment in thought and action. This involves two related dimensions:

• The ability to reason well and
• The disposition to do so.

Critical thinking involves logic as well as creativity. It may involve inductive and deductive reasoning, analysis and problem-solving as well as creative, innovative and complex approaches to the resolution of issues and challenges. One of the significant aims of education is to produce learners who are well informed, that is to say, learners should understand ideas that are important, useful, beautiful and powerful. Another is to create learners who have the appetite to think analytically and critically, to use what they know to enhance their own lives and also to contribute to their society, culture and civilization. Every pupil should have an effective skill of critical thinking, and they must not accept anything for granted It’s the ability of the child to think about anything and everything. An ability of critical thinking

Critical thinking should be encouraged. Traditional concepts of learning are loosing its charm. Text based passive learning is giving way to active thinking and learning process. The vital goal of education is to promote critical thinking in students, not making them reflect like a parrot. EYFS and KHDA are new terms that aim at improving the quality in education.

It’s really important to instil the ability of critical thinking in children through education. Early Years Foundation Stage is providing better guidance for children at a very tender age, they believe in individual abilities of children. There are Government bodies such as the KHDA in Dubai who takes the responsibility of the growth and quality of private education institutions.

As far as 21st century learning is concerned, critical thinking is an important factor. Spoon-feeding system in education has changed for better. It’s an era of better education.

It's Not a Memory Test; Education Needs to Focus on Critical Thinking

We're in the middle of finals season, and students are beginning to prepare for their exams by making lists, writing flashcards, and memorizing facts. High school education has evolved from learning to memorization, promoting answering rather than comprehending. 

A majority of students are focused more on obtaining good grades rather than understanding the concepts that are being taught.  When school systems prioritize the importance of grades over education, students are likely to resort to cheating.

Since I have been attending school, achieving and maintaining good grades has always been my top priority. In elementary and middle school, I had no trouble reaching the goals that I had set out for myself. When I entered high school, material became harder. I spend more time memorizing facts and equations rather than studying or learning the concepts. When given a lab or a critical question, I have difficulty coming up with an answer because I had never fully grasped the idea. Learning through experience, a student is less likely to be engaged in topic if they know they can memorize facts and never critically think. 

In recent years, standardized testing has becoming increasingly more popular, and in public education, funding is often given to schools with the highest standardized test scores. According to the Washington Post , students between kindergarten and 12th grade take roughly 112 standardized tests. 

Since the basis of questions on standardized tests are multiple choice and promote memorization, students can memorize a series of facts and be able to spit them out for the test; afterwards, the information that was memorized will quickly be forgotten. These tests typically lack any form of critical thinking. Teachers are more likely to teach information that will appear on these tests, and this reduces the quality of the education that a student receives. 

I have seen many students turn to cheating in order to avoid failing or getting anything lower than an A. They feel pressured to achieve good grades even if it means using unethical methods. Teachers commend their high tests scores, but they do not realize that the grades were achieved unfairly. 

According to the Open Education Database , a study done at Fordham University found that the average GPA for cheaters was higher than that of non-cheaters. Good grades are being valued higher than an honor system. 

How do we solve this issue? The evaluations that teachers give us could include more critical thinking questions. This would mean that less multiple choice questions should be given and more analysis of data, readings, and case studies. 

Critical thinking is what is lacking in many high school education programs. Learning these skills now would make college an easier transition, and standardized tests could be given less frequently. 

Learning and fully understanding a concept will help us come up with more creative ways to solve problems, and we will be able to apply the concepts in other situations, and combine new knowledge with what we already know. 

Memorization does not help you completely grasp the idea or give you the ability to apply the concept to another problem. If a person memorizes the definition of a word, but they cannot use it in a sentence, they do not truly know the meaning of the word. Memorization will always play a key factor in the education system, but the idea that it is more important to understand the concept should be emphasized.

An Evaluative Review of Barriers to Critical Thinking in Educational and Real-World Settings

Associated data.

No new data were created or analyzed in this study. Data sharing is not applicable to this article.

Though a wide array of definitions and conceptualisations of critical thinking have been offered in the past, further elaboration on some concepts is required, particularly with respect to various factors that may impede an individual’s application of critical thinking, such as in the case of reflective judgment. These barriers include varying levels of epistemological engagement or understanding, issues pertaining to heuristic-based thinking and intuitive judgment, as well as emotional and biased thinking. The aim of this review is to discuss such barriers and evaluate their impact on critical thinking in light of perspectives from research in an effort to reinforce the ‘completeness’ of extant critical thinking frameworks and to enhance the potential benefits of implementation in real-world settings. Recommendations and implications for overcoming such barriers are also discussed and evaluated.

1. Introduction

Critical thinking (CT) is a metacognitive process—consisting of a number of skills and dispositions—that, through purposeful, self-regulatory reflective judgment, increases the chances of producing a logical solution to a problem or a valid conclusion to an argument ( Dwyer 2017 , 2020 ; Dwyer et al. 2012 , 2014 , 2015 , 2016 ; Dwyer and Walsh 2019 ; Quinn et al. 2020 ).

CT has long been identified as a desired outcome of education ( Bezanilla et al. 2019 ; Butler et al. 2012 ; Dwyer 2017 ; Ennis 2018 ), given that it facilitates a more complex understanding of information ( Dwyer et al. 2012 ; Halpern 2014 ), better judgment and decision-making ( Gambrill 2006 ) and less dependence on cognitive bias and heuristic thinking ( Facione and Facione 2001 ; McGuinness 2013 ). A vast body of research (e.g., Dwyer et al. 2012 ; Gadzella 1996 ; Hitchcock 2004 ; Reed and Kromrey 2001 ; Rimiene 2002 ; Solon 2007 ), including various meta-analyses (e.g., Abrami et al. 2008 , 2015 ; Niu et al. 2013 ; Ortiz 2007 ), indicates that CT can be enhanced through targeted, explicit instruction. Though CT can be taught in domain-specific areas, its domain-generality means that it can be taught across disciplines and in relation to real-world scenarios ( Dwyer 2011 , 2017 ; Dwyer and Eigenauer 2017 ; Dwyer et al. 2015 ; Gabennesch 2006 ; Halpern 2014 ). Indeed, the positive outcomes associated with CT transcend educational settings into real-world, everyday situations, which is important because CT is necessary for a variety of social and interpersonal contexts where good decision-making and problem-solving are needed on a daily basis ( Ku 2009 ). However, regardless of domain-specificity or domain-generality of instruction, the transferability of CT application has been an issue in CT research (e.g., see Dumitru 2012 ). This is an important consideration because issues with transferability—for example, in real-world settings—may imply something lacking in CT instruction.

In light of the large, aforementioned body of research focusing on enhancing CT through instruction, a growing body of research has also evaluated the manner in which CT instruction is delivered (e.g., Abrami et al. 2008 , 2015 ; Ahern et al. 2019 ; Cáceres et al. 2020 ; Byerly 2019 ; Dwyer and Eigenauer 2017 ), along with additional considerations for and the barriers to such education, faced by teachers and students alike (e.g., Aliakbari and Sadeghdaghighi 2013 ; Cáceres et al. 2020 ; Cornell et al. 2011 ; Lloyd and Bahr 2010 ; Ma and Liu 2022 ; Ma and Luo 2021 ; Rear 2019 ; Saleh 2019 ); for example, those regarding conceptualisation, beliefs about CT, having feasible time for CT application and CT’s aforementioned transferability. However, there is a significant lack of research investigating barriers to CT application by individuals in real-world settings, even by those who have enjoyed benefits from previous CT instruction. Thus, perhaps the previously conjectured ‘something lacking in CT instruction’ refers to, in conjunction with the teaching of what CT consists of, making clear to students what barriers to CT application we face.

Simply, CT instruction is designed in such a way as to enhance the likelihood of positive decision-making outcomes. However, there are a variety of barriers that can impede an individual’s application of CT, regardless of past instruction with respect to ‘how to conduct CT’. For example, an individual might be regarded as a ‘critical thinker’ because they apply it in a vast majority of appropriate scenarios, but that does not ensure that they apply CT in all such appropriate scenarios. What keeps them from applying CT in those scenarios might well be one of a number of barriers to CT that often go unaddressed in CT instruction, particularly if such instruction is exclusively focused on skills and dispositions. Perhaps too much focus is placed on what educators are teaching their students to do in their CT courses as opposed to what educators should be recommending their students to look out for or advising what they should not be doing. That is, perhaps just as important for understanding what CT is and how it is conducted (i.e., knowing what to do) is a genuine awareness of the various factors and processes that can impede CT; and so, for an individual to think critically, they must know what to look out for and be able to monitor for such barriers to CT application.

To clarify, thought has not changed regarding what CT is or the cognitive/metacognitive processes at its foundation (e.g., see Dwyer 2017 ; Dwyer et al. 2014 ; Ennis 1987 , 1996 , 1998 ; Facione 1990 ; Halpern 2014 ; Paul 1993 ; Paul and Elder 2008 ); rather, additional consideration of issues that have potential to negatively impact CT is required, such as those pertaining to epistemological engagement; intuitive judgment; as well as emotional and biased thinking. This notion has been made clear through what might be perceived of as a ‘loud shout’ for CT over at least the past 10–15 years in light of growing political, economic, social, and health-related concerns (e.g., ‘fake news’, gaps between political views in the general population, various social movements and the COVID-19 pandemic). Indeed, there is a dearth of research on barriers to CT ( Haynes et al. 2016 ; Lloyd and Bahr 2010 ; Mangena and Chabeli 2005 ; Rowe et al. 2015 ). As a result, this evaluative perspective review aims to provide an impetus for updating the manner in which CT education is approached and, perhaps most importantly, applied in real-world settings—through further identifying and elaborating on specific barriers of concern in order to reinforce the ‘completeness’ of extant CT frameworks and to enhance the potential benefits of their implementation 1 .

2. Barriers to Critical Thinking

2.1. inadequate skills and dispositions.

In order to better understand the various barriers to CT that will be discussed, the manner in which CT is conceptualised must first be revisited. Though debate over its definition and what components are necessary to think critically has existed over the 80-plus years since the term’s coining (i.e., Glaser 1941 ), it is generally accepted that CT consists of two main components: skills and dispositions ( Dwyer 2017 ; Dwyer et al. 2012 , 2014 ; Ennis 1996 , 1998 ; Facione 1990 ; Facione et al. 2002 ; Halpern 2014 ; Ku and Ho 2010a ; Perkins and Ritchhart 2004 ; Quinn et al. 2020 ). CT skills—analysis, evaluation, and inference—refer to the higher-order, cognitive, ‘task-based’ processes necessary to conduct CT (e.g., see Dwyer et al. 2014 ; Facione 1990 ). CT dispositions have been described as inclinations, tendencies, or willingness to perform a given thinking skill (e.g., see Dwyer et al. 2016 ; Siegel 1999 ; Valenzuela et al. 2011 ), which may relate to attitudinal and intellectual habits of thinking, as well as motivational processes ( Ennis 1996 ; Norris 1994 ; Paul and Elder 2008 ; Perkins et al. 1993 ; Valenzuela et al. 2011 ). The relationship between CT skills and dispositions has been argued to be mutually dependent. As a result, overemphasising or encouraging the development of one over the other is a barrier to CT as a whole. Though this may seem obvious, it remains the case that CT instruction often places added emphasis on skills simply because they can be taught (though that does not ensure that everyone has or will be taught such skills), whereas dispositions are ‘trickier’ (e.g., see Dwyer 2017 ; Ku and Ho 2010a ). That is, it is unlikely that simply ‘teaching’ students to be motivated towards CT or to value it over short-instructional periods will actually meaningfully enhance it. Moreover, debate exists over how best to train disposition or even measure it. With that, some individuals might be more ‘inherently’ disposed to CT in light of their truth-seeking, open-minded, or inquisitive natures ( Facione and Facione 1992 ; Quinn et al. 2020 ). The barrier, in this context, is how we can enhance the disposition of those who are not ‘inherently’ inclined. For example, though an individual may possess the requisite skills to conduct CT, it does not ensure the tendency or willingness to apply them; and conversely, having the disposition to apply CT does not mean that one has the ability to do so ( Valenzuela et al. 2011 ). Given the pertinence of CT skills and dispositions to the application of CT in a broader sense, inadequacies in either create a barrier to application.

2.2. Epistemological (Mis)Understanding

To reiterate, most extant conceptualisations of CT focus on the tandem working of skills and dispositions, though significantly fewer emphasise the reflective judgment aspect of CT that might govern various associated processes ( Dawson 2008 ; Dwyer 2017 ; Dwyer et al. 2014 , 2015 ; King and Kitchener 1994 , 2004 ; Stanovich and Stanovich 2010 ). Reflective judgment (RJ) refers to a self-regulatory process of decision-making, with respect to taking time to engage one’s understanding of the nature, limits, and certainty of knowing and how this can affect the defense of their reasoning ( Dwyer 2017 ; King and Kitchener 1994 ; Ku and Ho 2010b ). The ability to metacognitively ‘think about thinking’ ( Flavell 1976 ; Ku and Ho 2010b ) in the application of critical thinking skills implies a reflective sensibility consistent with epistemological understanding and the capacity for reflective judgement ( Dwyer et al. 2015 ; King and Kitchener 1994 ). Acknowledging levels of (un)certainty is important in CT because the information a person is presented with (along with that person’s pre-existing knowledge) often provides only a limited source of information from which to draw a conclusion. Thus, RJ is considered a component of CT ( Baril et al. 1998 ; Dwyer et al. 2015 ; Huffman et al. 1991 ) because it allows one to acknowledge that epistemological understanding is necessary for recognising and judging a situation in which CT may be required ( King and Kitchener 1994 ). For example, the interdependence between RJ and CT can be seen in the way that RJ influences the manner in which CT skills like analysis and evaluation are conducted or the balance and perspective within the subsequent inferences drawn ( Dwyer et al. 2015 ; King et al. 1990 ). Moreover, research suggests that RJ development is not a simple function of age or time but more so a function of the amount of active engagement an individual has working in problem spaces that require CT ( Brabeck 1981 ; Dawson 2008 ; Dwyer et al. 2015 ). The more developed one’s RJ, the better able one is to present “a more complex and effective form of justification, providing more inclusive and better integrated assumptions for evaluating and defending a point of view” ( King and Kitchener 1994, p. 13 ).

Despite a lesser focus on RJ, research indicates a positive relationship between it and CT ( Baril et al. 1998 ; Brabeck 1981 ; Dawson 2008 ; Dwyer et al. 2015 ; Huffman et al. 1991 ; King et al. 1990 )—the understanding of which is pertinent to better understanding the foundation to CT barriers. For example, when considering one’s proficiency in CT skills, there might come a time when the individual becomes so good at using them that their application becomes something akin to ‘second nature’ or even ‘automatic’. However, this creates a contradiction: automatic thinking is largely the antithesis of reflective judgment (even though judgment is never fully intuitive or reflective; see Cader et al. 2005 ; Dunwoody et al. 2000 ; Hamm 1988 ; Hammond 1981 , 1996 , 2000 )—those who think critically take their time and reflect on their decision-making; even if the solution/conclusion drawn from the automatic thinking is ‘correct’ or yields a positive outcome, it is not a critically thought out answer, per se. Thus, no matter how skilled one is at applying CT skills, once the application becomes primarily ‘automatic’, the thinking ceases to be critical ( Dwyer 2017 )—a perspective consistent with Dual Process Theory (e.g., Stanovich and West 2000 ). Indeed, RJ acts as System 2 thinking ( Stanovich and West 2000 ): it is slow, careful, conscious, and consistent ( Kahneman 2011 ; Hamm 1988 ); it is associated with high cognitive control, attention, awareness, concentration, and complex computation ( Cader et al. 2005 ; Kahneman 2011 ; Hamm 1988 ); and accounts for epistemological concerns—consistent not only with King and Kitchener’s ( 1994 ) conceptualisation but also Kuhn’s ( 1999 , 2000 ) perspective on metacognition and epistemological knowing . This is where RJ comes into play as an important component of CT—interdependent among the requisite skills and dispositions ( Baril et al. 1998 ; Dwyer et al. 2015 )—it allows one to acknowledge that epistemological understanding is vital to recognising and judging a situation in which CT is required ( King and Kitchener 1994 ). With respect to the importance of epistemological understanding, consider the following examples for elaboration.

The primary goal of CT is to enhance the likelihood of generating reasonable conclusions and/or solutions. Truth-seeking is a CT disposition fundamental to the attainment of this goal ( Dwyer et al. 2016 ; Facione 1990 ; Facione and Facione 1992 ) because if we just applied any old nonsense as justification for our arguments or solutions, they would fail in the application and yield undesirable consequences. Despite what may seem like truth-seeking’s obvious importance in this context, all thinkers succumb to unwarranted assumptions on occasion (i.e., beliefs presumed to be true without adequate justification). It may also seem obvious, in context, that it is important to be able to distinguish facts from beliefs. However, the concepts of ‘fact’ or ‘truth’, with respect to how much empirical support they have to validate them, also require consideration. For example, some might conceptualise truth as factual information or information that has been or can be ‘proven’ true. Likewise, ‘proof’ is often described as evidence establishing a fact or the truth of a statement—indicating a level of absolutism. However, the reality is that we cannot ‘prove’ things—as scientists and researchers well know—we can only disprove them, such as in experimental settings where we observe a significant difference between groups on some measure—we do not prove the hypothesis correct, rather, we disprove the null hypothesis. This is why, in large part, researchers and scientists use cautious language in reporting their results. We know the best our findings can do is reinforce a theory—another concept often misconstrued in the wider population as something like a hypothesis, as opposed to what it actually entails: a robust model for how and/or why a given phenomenon might occur (e.g., gravity). Thus, theories will hold ‘true’ until they are falsified—that is, disproven (e.g., Popper [1934] 1959 , 1999 ).

Unfortunately, ‘proof’, ‘prove’, and ‘proven’—words that ensure certainty to large populations—actually disservice the public in subtle ways that can hinder CT. For example, a company that produces toothpaste might claim its product to be ‘clinically proven’ to whiten teeth. Consumers purchasing that toothpaste are likely to expect to have whiter teeth after use. However, what happens—as often may be the case—if it does not whiten their teeth? The word ‘proven’ implies a false claim in context. Of course, those in research understand that the word’s use is a marketing ploy, given that ‘clinically proven’ sounds more reassuring to consumers than ‘there is evidence to suggest…’; but, by incorrectly using words like ‘proven’ in our daily language, we reinforce a misunderstanding of what it means to assess, measure and evaluate—particularly from a scientific standpoint (e.g., again, see Popper [1934] 1959 , 1999 ).

Though this example may seem like a semantic issue, it has great implications for CT in the population. For example, a vast majority of us grew up being taught the ‘factual’ information that there were nine planets in our solar system; then, in 2006, Pluto was reclassified as a dwarf planet—no longer being considered a ‘major’ planet of our solar system. As a result, we now have eight planets. This change might be perceived in two distinct ways: (1) ‘science is amazing because it’s always developing—we’ve now reached a stage where we know so much about the solar system that we can differentiate celestial bodies to the extent of distinguishing planets from dwarf planets’; and (2) ‘I don’t understand why these scientists even have jobs, they can’t even count planets’. The first perspective is consistent with that of an individual with epistemological understanding and engagement that previous understandings of models and theories can change, not necessarily because they were wrong, but rather because they have been advanced in light of gaining further credible evidence. The second perspective is consistent with that of someone who has failed to engage epistemological understanding, who does not necessarily see that the change might reflect progress, who might be resistant to change, and who might grow in distrust of science and research in light of these changes. The latter point is of great concern in the CT research community because the unwarranted cynicism and distrust of science and research, in context, may simply reflect a lack of epistemological understanding or engagement (e.g., to some extent consistent with the manner in which conspiracy theories are developed, rationalised and maintained (e.g., Swami and Furnham 2014 )). Notably, this should also be of great concern to education departments around the world, as well as society, more broadly speaking.

Upon considering epistemological engagement in more practical, day-to-day scenarios (or perhaps a lack thereof), we begin to see the need for CT in everyday 21st-century life—heightened by the ‘new knowledge economy’, which has resulted in exponential increases in the amount of information made available since the late 1990s (e.g., Darling-Hammond 2008 ; Dwyer 2017 ; Jukes and McCain 2002 ; Varian and Lyman 2003 ). Though increased amounts of and enhanced access to information are largely good things, what is alarming about this is how much of it is misinformation or disinformation ( Commission on Fake News and the Teaching of Critical Literacy in Schools 2018 ). Truth be told, the new knowledge economy is anything but ‘new’ anymore. Perhaps, over the past 10–15 years, there has been an increase in the need for CT above and beyond that seen in the ‘economy’s’ wake—or maybe ever before; for example, in light of the social media boom, political unrest, ‘fake news’, and issues regarding health literacy. The ‘new’ knowledge economy has made it so that knowledge acquisition, on its own, is no longer sufficient for learning—individuals must be able to work with and adapt information through CT in order to apply it appropriately ( Dwyer 2017 ).

Though extant research has addressed the importance of epistemological understanding for CT (e.g., Dwyer et al. 2014 ), it does not address how not engaging it can substantially hinder it—regardless of how skilled or disposed to think critically an individual may be. Notably, this is distinct from ‘inadequacies’ in, say, memory, comprehension, or other ‘lower-order’ cognitively-associated skills required for CT ( Dwyer et al. 2014 ; Halpern 2014 ; see, again, Note 1) in that reflective judgment is essentially a pole on a cognitive continuum (e.g., see Cader et al. 2005 ; Hamm 1988 ; Hammond 1981 , 1996 , 2000 ). Cognitive Continuum Theory postulates a continuum of cognitive processes anchored by reflective judgment and intuitive judgment, which represents how judgment situations or tasks relate to cognition, given that thinking is never purely reflective, nor is it completely intuitive; rather, it rests somewhere in between ( Cader et al. 2005 ; Dunwoody et al. 2000 ). It is also worth noting that, in Cognitive Continuum Theory, neither reflective nor intuitive judgment is assumed, a priori, to be superior ( Dunwoody et al. 2000 ), despite most contemporary research on judgment and decision-making focusing on the strengths of RJ and limitations associated with intuitive judgment ( Cabantous et al. 2010 ; Dhami and Thomson 2012 ; Gilovich et al. 2002 ). Though this point regarding superiority is acknowledged and respected (particularly in non-CT cases where it is advantageous to utilise intuitive judgment), in the context of CT, it is rejected in light of the example above regarding the automaticity of thinking skills.

2.3. Intuitive Judgment

The manner in which human beings think and the evolution of which, over millions of years, is a truly amazing thing. Such evolution has made it so that we can observe a particular event and make complex computations regarding predictions, interpretations, and reactions in less than a second (e.g., Teichert et al. 2014 ). Unfortunately, we have become so good at it that we often over-rely on ‘fast’ thinking and intuitive judgments that we have become ‘cognitively lazy’, given the speed at which we can make decisions with little energy ( Kahneman 2011 ; Simon 1957 ). In the context of CT, this ‘lazy’ thinking is an impediment (as in opposition to reflective judgment). For example, consider a time in which you have been presented numeric data on a topic, and you instantly aligned your perspective with what the ‘numbers indicate’. Of course, numbers do not lie… but people do—that is not to say that the person who initially interpreted and then presented you with those numbers is trying to disinform you; rather, the numbers presented might not tell the full story (i.e., the data are incomplete or inadequate, unbeknownst to the person reporting on them); and thus, there might be alternative interpretations to the data in question. With that, there most certainly are individuals who will wish to persuade you to align with their perspective, which only strengthens the impetus for being aware of intuitive judgment as a barrier. Consider another example: have you ever accidentally insulted someone at work, school, or in a social setting? Was it because the statement you made was based on some kind of assumption or stereotype? It may have been an honest mistake, but if a statement is made based on what one thinks they know, as opposed to what they actually know about the situation—without taking the time to recognise that all situations are unique and that reflection is likely warranted in light of such uncertainty—then it is likely that the schema-based ‘intuitive judgment’ is what is a fault here.

Our ability to construct schemas (i.e., mental frameworks for how we interpret the world) is evolutionarily adaptive in that these scripts allow us to: make quick decisions when necessary and without much effort, such as in moments of impending danger, answer questions in conversation; interpret social situations; or try to stave off cognitive load or decision fatigue ( Baumeister 2003 ; Sweller 2010 ; Vohs et al. 2014 ). To reiterate, research in the field of higher-order thinking often focuses on the failings of intuitive judgment ( Dwyer 2017 ; Hamm 1988 ) as being limited, misapplied, and, sometimes, yielding grossly incorrect responses—thus, leading to faulty reasoning and judgment as a result of systematic biases and errors ( Gilovich et al. 2002 ; Kahneman 2011 ; Kahneman et al. 1982 ; Slovic et al. 1977 ; Tversky and Kahneman 1974 ; in terms of schematic thinking ( Leventhal 1984 ), system 1 thinking ( Stanovich and West 2000 ; Kahneman 2011 ), miserly thinking ( Stanovich 2018 ) or even heuristics ( Kahneman and Frederick 2002 ; Tversky and Kahneman 1974 ). Nevertheless, it remains that such protocols are learned—not just through experience (as discussed below), but often through more ‘academic’ means. For example, consider again the anecdote above about learning to apply CT skills so well that it becomes like ‘second nature’. Such skills become a part of an individual’s ‘mindware’ ( Clark 2001 ; Stanovich 2018 ; Stanovich et al. 2016 ) and, in essence, become heuristics themselves. Though their application requires RJ for them to be CT, it does not mean that the responses yielded will be incorrect.

Moreover, despite the descriptions above, it would be incorrect, and a disservice to readers to imply that RJ is always right and intuitive judgment is always wrong, especially without consideration of the contextual issues—both intuitive and reflective judgments have the potential to be ‘correct’ or ‘incorrect’ with respect to validity, reasonableness or appropriateness. However, it must also be acknowledged that there is a cognitive ‘miserliness’ to depending on intuitive judgment, in which case, the ability to detect and override this dependence ( Stanovich 2018 )—consistent with RJ, is of utmost importance if we care about our decision-making. That is, if we care about our CT (see below for a more detailed discussion), we must ignore the implicit ‘noise’ associated with the intuitive judgment (regardless of whether or not it is ‘correct’) and, instead, apply the necessary RJ to ensure, as best we can, that the conclusion or solution is valid, reasonable or appropriate.

Although, such a recommendation is much easier said than done. One problem with relying on mental shortcuts afforded by intuition and heuristics is that they are largely experience-based protocols. Though that may sound like a positive thing, using ‘experience’ to draw a conclusion in a task that requires CT is erroneous because it essentially acts as ‘research’ based on a sample size of one; and so, ‘findings’ (i.e., one’s conclusion) cannot be generalised to the larger population—in this case, other contexts or problem-spaces ( Dwyer 2017 ). Despite this, we often over-emphasise the importance of experience in two related ways. First, people have a tendency to confuse experience for expertise (e.g., see the Dunning–KrugerEffect (i.e., the tendency for low-skilled individuals to overestimate their ability in tasks relevant to said skill and highly skilled individuals to underestimate their ability in tasks relevant to said skills); see also: ( Kruger and Dunning 1999 ; Mahmood 2016 ), wherein people may not necessarily be expert, rather they may just have a lot of experience completing a task imperfectly or wrong ( Dwyer and Walsh 2019 ; Hammond 1996 ; Kahneman 2011 ). Second, depending on the nature of the topic or problem, people often evaluate experience on par with research evidence (in terms of credibility), given its personalised nature, which is reinforced by self-serving bias(es).

When evaluating topics in domains wherein one lacks expertise, the need for intellectual integrity and humility ( Paul and Elder 2008 ) in their RJ is increased so that the individual may assess what knowledge is required to make a critically considered judgment. However, this is not necessarily a common response to a lack of relevant knowledge, given that when individuals are tasked with decision-making regarding a topic in which they do not possess relevant knowledge, these individuals will generally rely on emotional cues to inform their decision-making (e.g., Kahneman and Frederick 2002 ). Concerns here are not necessarily about the lack of domain-specific knowledge necessary to make an accurate decision, but rather the (1) belief of the individual that they have the knowledge necessary to make a critically thought-out judgment, even when this is not the case—again, akin to the Dunning–Kruger Effect ( Kruger and Dunning 1999 ); or (2) lack of willingness (i.e., disposition) to gain additional, relevant topic knowledge.

One final problem with relying on experience for important decisions, as alluded to above, is that when experience is engaged, it is not necessarily an objective recollection of the procedure. It can be accompanied by the individual’s beliefs, attitudes, and feelings—how that experience is recalled. The manner in which an individual draws on their personal experience, in light of these other factors, is inherently emotion-based and, likewise, biased (e.g., Croskerry et al. 2013 ; Loftus 2017 ; Paul 1993 ).

2.4. Bias and Emotion

Definitions of CT often reflect that it is to be applied to a topic, argument, or problem of importance that the individual cares about ( Dwyer 2017 ). The issue of ‘caring’ is important because it excludes judgment and decision-making in day-to-day scenarios that are not of great importance and do not warrant CT (e.g., ‘what colour pants best match my shirt’ and ‘what to eat for dinner’); again, for example, in an effort to conserve time and cognitive resources (e.g., Baumeister 2003 ; Sweller 2010 ). However, given that ‘importance’ is subjective, it essentially boils down to what one cares about (e.g., issues potentially impactful in one’s personal life; topics of personal importance to the individual; or even problems faced by an individual’s social group or work organisation (in which case, care might be more extrinsically-oriented). This is arguably one of the most difficult issues to resolve in CT application, given its contradictory nature—where it is generally recommended that CT should be conducted void of emotion and bias (as much as it can be possible), at the same time, it is also recommended that it should only be applied to things we care about. As a result, the manner in which care is conceptualised requires consideration. For example, in terms of CT, care can be conceptualised as ‘concern or interest; the attachment of importance to a person, place, object or concept; and serious attention or consideration applied to doing something correctly or to avoid damage or risk’; as opposed to some form of passion (e.g., intense, driving or over-powering feeling or conviction; emotions as distinguished from reason; a strong liking or desire for or devotion to some activity, object or concept). In this light, care could be argued as more of a dispositional or self-regulatory factor than emotional bias; thus, making it useful to CT. Though this distinction is important, the manner in which care is labeled does not lessen the potential for biased emotion to play a role in the thinking process. For example, it has been argued that if one cares about the decision they make or the conclusion they draw, then the individual will do their best to be objective as possible ( Dwyer 2017 ). However, it must also be acknowledged that this may not always be the case or even completely feasible (i.e., how can any decision be fully void of emotional input? )—though one may strive to be as objective as possible, such objectivity is not ensured given that implicit bias may infiltrate their decision-making (e.g., taking assumptions for granted as facts in filling gaps (unknowns) in a given problem-space). Consequently, such implicit biases may be difficult to amend, given that we may not be fully aware of them at play.

With that, explicit biases are just as concerning, despite our awareness of them. For example, the more important an opinion or belief is to an individual, the greater the resistance to changing their mind about it ( Rowe et al. 2015 ), even in light of evidence indicating the contrary ( Tavris and Aronson 2007 ). In some cases, the provision of information that corrects the flawed concept may even ‘backfire’ and reinforce the flawed or debunked stance ( Cook and Lewandowsky 2011 ). This cognitive resistance is an important barrier to CT to consider for obvious reasons—as a process; it acts in direct opposition to RJ, the skill of evaluation, as well as a number of requisite dispositions towards CT, including truth-seeking and open-mindedness (e.g., Dwyer et al. 2014 , 2016 ; Facione 1990 ); and at the same time, yields important real-world impacts (e.g., see Nyhan et al. 2014 ).

The notion of emotion impacting rational thought is by no means a novel concept. A large body of research indicates a negative impact of emotion on decision-making (e.g., Kahneman and Frederick 2002 ; Slovic et al. 2002 ; Strack et al. 1988 ), higher-order cognition ( Anticevic et al. 2011 ; Chuah et al. 2010 ; Denkova et al. 2010 ; Dolcos and McCarthy 2006 ) and cognition, more generally ( Iordan et al. 2013 ; Johnson et al. 2005 ; Most et al. 2005 ; Shackman et al. 2006 ) 2 . However, less attention has specifically focused on emotion’s impact on the application of critical thought. This may be a result of assumptions that if a person is inclined to think critically, then what is yielded will typically be void of emotion—which is true to a certain extent. However, despite the domain generality of CT ( Dwyer 2011 , 2017 ; Dwyer and Eigenauer 2017 ; Dwyer et al. 2015 ; Gabennesch 2006 ; Halpern 2014 ), the likelihood of emotional control during the CT process remains heavily dependent on the topic of application. Consider again, for example; there is no guarantee that an individual who generally applies CT to important topics or situations will do so in all contexts. Indeed, depending on the nature of the topic or the problem faced, an individual’s mindware ( Clark 2001 ; Stanovich 2018 ; Stanovich et al. 2016 ; consistent with the metacognitive nature of CT) and the extent to which a context can evoke emotion in the thinker will influence what and how thinking is applied. As addressed above, if the topic is something to which the individual feels passionate, then it will more likely be a greater challenge for them to remain unbiased and develop a reasonably objective argument or solution.

Notably, self-regulation is an important aspect of both RJ and CT ( Dwyer 2017 ; Dwyer et al. 2014 ), and, in this context, it is difficult not to consider the role emotional intelligence might play in the relationship between affect and CT. For example, though there are a variety of conceptualisations of emotional intelligence (e.g., Bar-On 2006 ; Feyerherm and Rice 2002 ; Goleman 1995 ; Salovey and Mayer 1990 ; Schutte et al. 1998 ), the underlying thread among these is that, similar to the concept of self-regulation, emotional intelligence (EI) refers to the ability to monitor (e.g., perceive, understand and regulate) one’s own feelings, as well as those of others, and to use this information to guide relevant thinking and behaviour. Indeed, extant research indicates that there is a positive association between EI and CT (e.g., Afshar and Rahimi 2014 ; Akbari-Lakeh et al. 2018 ; Ghanizadeh and Moafian 2011 ; Kaya et al. 2017 ; Stedman and Andenoro 2007 ; Yao et al. 2018 ). To shed light upon this relationship, Elder ( 1997 ) addressed the potential link between CT and EI through her description of the latter as a measure of the extent to which affective responses are rationally-based , in which reasonable desires and behaviours emerge from such rationally-based emotions. Though there is extant research on the links between CT and EI, it is recommended that future research further elaborate on this relationship, as well as with other self-regulatory processes, in an effort to further establish the potentially important role that EI might play within CT.

3. Discussion

3.1. interpretations.

Given difficulties in the past regarding the conceptualisation of CT ( Dwyer et al. 2014 ), efforts have been made to be as specific and comprehensive as possible when discussing CT in the literature to ensure clarity and accuracy. However, it has been argued that such efforts have actually added to the complexity of CT’s conceptualisation and had the opposite effect on clarity and, perhaps, more importantly, the accessibility and practical usefulness for educators (and students) not working in the research area. As a result, when asked what CT is, I generally follow up the ‘long definition’, in light of past research, with a much simpler description: CT is akin to ‘playing devil’s advocate’. That is, once a claim is made, one should second-guess it in as many conceivable ways as possible, in a process similar to the Socratic Method. Through asking ‘why’ and conjecturing alternatives, we ask the individual—be it another person or even ourselves—to justify the decision-making. It keeps the thinker ‘honest’, which is particularly useful if we’re questioning ourselves. If we do not have justifiable reason(s) for why we think or intend to act in a particular way (above and beyond considered objections), then it should become obvious that we either missed something or we are biased. It is perhaps this simplified description of CT that gives such impetus for the aim of this review.

Whereas extant frameworks often discuss the importance of CT skills, dispositions, and, to a lesser extent, RJ and other self-regulatory functions of CT, they do so with respect to components of CT or processes that facilitate CT (e.g., motivation, executive functions, and dispositions), without fully encapsulating cognitive processes and other factors that may hinder it (e.g., emotion, bias, intuitive judgment and a lack of epistemological understanding or engagement). With that, this review is neither a criticism of existing CT frameworks nor is it to imply that CT has so many barriers that it cannot be taught well, nor does it claim to be a complete list of processes that can impede CT (see again Note 1). To reiterate, education in CT can yield beneficial effects ( Abrami et al. 2008 , 2015 ; Dwyer 2017 ; Dwyer and Eigenauer 2017 ); however, such efficacy may be further enhanced by presenting students and individuals interested in CT the barriers they are likely to face in its application; explaining how these barriers manifest and operate; and offer potential strategies for overcoming them.

3.2. Further Implications and Future Research

Though the barriers addressed here are by no means new to the arena of research in higher-order cognition, there is a novelty in their collated discussion as impactful barriers in the context of CT, particularly with respect to extant CT research typically focusing on introducing strategies and skills for enhancing CT, rather than identifying ‘preventative measures’ for barriers that can negatively impact CT. Nevertheless, future research is necessary to address how such barriers can be overcome in the context of CT. As addressed above, it is recommended that CT education include discussion of these barriers and encourage self-regulation against them; and, given the vast body of CT research focusing on enhancement through training and education, it seems obvious to make such a recommendation in this context. However, it is also recognised that simply identifying these barriers and encouraging people to engage in RJ and self-regulation to combat them may not suffice. For example, educators might very well succeed in teaching students how to apply CT skills , but just as these educators may not be able to motivate students to use them as often as they might be needed or even to value such skills (such as in attempting to elicit a positive disposition towards CT), it might be the case that without knowing about the impact of the discussed barriers to CT (e.g., emotion and/or intuitive judgment), students may be just as susceptible to biases in their attempts to think critically as others without CT skills. Thus, what such individuals might be applying is not CT at all; rather, just a series of higher-order cognitive skills from a biased or emotion-driven perspective. As a result, a genuine understanding of these barriers is necessary for individuals to appropriately self-regulate their thinking.

Moreover, though the issues of epistemological beliefs, bias, emotion, and intuitive processes are distinct in the manner in which they can impact CT, these do not have set boundaries; thus, an important implication is that they can overlap. For example, epistemological understanding can influence how individuals make decisions in real-world scenarios, such as through intuiting a judgment in social situations (i.e., without considering the nature of the knowledge behind the decision, the manner in which such knowledge interacts [e.g., correlation v. causation], the level of uncertainty regarding both the decision-maker’s personal stance and the available evidence), when a situation might actually require further consideration or even the honest response of ‘I don’t know’. The latter concept—that of simply responding ‘I don’t know’ is interesting to consider because though it seems, on the surface, to be inconsistent with CT and its outcomes, it is commensurate with many of its associated components (e.g., intellectual honesty and humility; see Paul and Elder 2008 ). In the context this example is used, ‘I don’t know’ refers to epistemological understanding. With that, it may also be impacted by bias and emotion. For example, depending on the topic, an individual may be likely to respond ‘I don’t know’ when they do not have the relevant knowledge or evidence to provide a sufficient answer. However, in the event that the topic is something the individual is emotionally invested in or feels passionate about, an opinion or belief may be shared instead of ‘I don’t know’ (e.g., Kahneman and Frederick 2002 ), despite a lack of requisite evidence-based knowledge (e.g., Kruger and Dunning 1999 ). An emotional response based on belief may be motivated in the sense that the individual knows that they do not know for sure and simply uses a belief to support their reasoning as a persuasive tool. On the other hand, the emotional response based on belief might be used simply because the individual may not know that the use of a belief is an insufficient means of supporting their perspective– instead, they might think that their intuitive, belief-based judgment is as good as a piece of empirical evidence; thus, suggesting a lack of empirical understanding. With that, it is fair to say that though epistemological understanding, intuitive judgment, emotion, and bias are distinct concepts, they can influence each other in real-world CT and decision-making. Though there are many more examples of how this might occur, the one presented may further support the recommendation that education can be used to overcome some of the negative effects associated with the barriers presented.

For example, in Ireland, students are not generally taught about academic referencing until they reach third-level education. Anecdotally, I was taught about referencing at age 12 and had to use it all the way through high school when I was growing up in New York. In the context of these referencing lessons, we were taught about the credibility of sources, as well as how analyse and evaluate arguments and subsequently infer conclusions in light of these sources (i.e., CT skills). We were motivated by our teacher to find the ‘truth’ as best we could (i.e., a fundament of CT disposition). Now, I recognise that this experience cannot be generalised to larger populations, given that I am a sample size of one, but I do look upon such education, perhaps, as a kind of transformative learning experience ( Casey 2018 ; King 2009 ; Mezirow 1978 , 1990 ) in the sense that such education might have provided a basis for both CT and epistemological understanding. For CT, we use research to support our positions, hence the importance of referencing. When a ‘reference’ is not available, one must ask if there is actual evidence available to support the proposition. If there is not, one must question the basis for why they think or believe that their stance is correct—that is, where there is logic to the reasoning or if the proposition is simply an emotion- or bias-based intuitive judgment. So, in addition to referencing, the teaching of some form of epistemology—perhaps early in children’s secondary school careers, might benefit students in future efforts to overcome some barriers to CT. Likewise, presenting examples of the observable impact that bias, emotions, and intuitive thought can have on their thinking might also facilitate overcoming these barriers.

As addressed above, it is acknowledged that we may not be able to ‘teach’ people not to be biased or emotionally driven in their thinking because it occurs naturally ( Kahneman 2011 )—regardless of how ‘skilled’ one might be in CT. For example, though research suggests that components of CT, such as disposition, can improve over relatively short periods of time (e.g., over the duration of a semester-long course; Rimiene 2002 ), less is known about how such components have been enhanced (given the difficulty often associated with trying to teach something like disposition ( Dwyer 2017 ); i.e., to reiterate, it is unlikely that simply ‘teaching’ (or telling) students to be motivated towards CT or to value it (or its associated concepts) will actually enhance it over short periods of time (e.g., semester-long training). Nevertheless, it is reasonable to suggest that, in light of such research, educators can encourage dispositional growth and provide opportunities to develop it. Likewise, it is recommended that educators encourage students to be aware of the cognitive barriers discussed and provide chances to engage in CT scenarios where such barriers are likely to play a role, thus, giving students opportunities to acknowledge the barriers and practice overcoming them. Moreover, making students aware of such barriers at younger ages—in a simplified manner, may promote the development of personal perspectives and approaches that are better able to overcome the discussed barriers to CT. This perspective is consistent with research on RJ ( Dwyer et al. 2015 ), in which it was recommended that such enhancement requires not only time to develop (be it over the course of a semester or longer) but is also a function of having increased opportunities to engage CT. In the possibilities described, individuals may learn both to overcome barriers to CT and from the positive outcomes of applying CT; and, perhaps, engage in some form of transformative learning ( Casey 2018 ; King 2009 ; Mezirow 1978 , 1990 ) that facilitates an enhanced ‘valuing’ of and motivation towards CT. For example, through growing an understanding of the nature of epistemology, intuitive-based thinking, emotion, bias, and the manner in which people often succumb to faulty reasoning in light of these, individuals may come to better understand the limits of knowledge, barriers to CT and how both understandings can be applied; thus, growing further appreciation of the process as it is needed.

To reiterate, research suggests that there may be a developmental trajectory above and beyond the parameters of a semester-long training course that is necessary to develop the RJ necessary to think critically and, likewise, engage an adequate epistemological stance and self-regulate against impeding cognitive processes ( Dwyer et al. 2015 ). Though such research suggests that such development may not be an issue of time, but rather the amount of opportunities to engage RJ and CT, there is a dearth of recommendations offered with respect to how this could be performed in practice. Moreover, the how and what regarding ‘opportunities for engagement’ requires further investigation as well. For example, does this require additional academic work outside the classroom in a formal manner, or does it require informal ‘exploration’ of the world of information on one’s own? If the latter, the case of motivational and dispositional levels once again comes into question; thus, even further consideration is needed. One way or another, future research efforts are necessary to identify how best to make individuals aware of barriers to CT, encourage them to self-regulate against them, and identify means of increasing opportunities to engage RJ and CT.

4. Conclusions

Taking heed that it is unnecessary to reinvent the CT wheel ( Eigenauer 2017 ), the aim of this review was to further elaborate on the processes associated with CT and make a valuable contribution to its literature with respect to conceptualisation—not just in light of making people explicitly aware of what it is, but also what it is not and how it can be impeded (e.g., through inadequate CT skills and dispositions; epistemological misunderstanding; intuitive judgment; as well as bias and emotion)—a perspective consistent with that of ‘constructive feedback’ wherein students need to know both what they are doing right and what they are doing wrong. This review further contributes to the CT education literature by identifying the importance of (1) engaging understanding of the nature, limits, and certainty of knowing as individuals traverse the landscape of evidence-bases in their research and ‘truth-seeking’; (2) understanding how emotions and biases can affect CT, regardless of the topic; (3) managing gut-level intuition until RJ has been appropriately engaged; and (4) the manner in which language is used to convey meaning to important and/or abstract concepts (e.g., ‘caring’, ‘proof’, causation/correlation, etc.). Consistent with the perspectives on research advancement presented in this review, it is acknowledged that the issues addressed here may not be complete and may themselves be advanced upon and updated in time; thus, future research is recommended and welcomed to improve and further establish our working conceptualisation of critical thinking, particularly in a real-world application.

1 Notably, though inadequacies in cognitive resources (apart from those explicitly set within the conceptualisations of CT discussed; e.g., see Section 2.1 ) are acknowledged as impediments to one’s ability to apply CT (e.g., a lack of relevant background knowledge, as well as broader cognitive abilities and resources ( Dwyer 2017 ; Halpern 2014 ; Stanovich and Stanovich 2010 )), these will not be discussed as focus is largely restricted to issues of cognitive processes that ‘naturally’ act as barriers in their functioning. Moreover, such inadequacies may more so be issues of individual differences than ongoing issues that everyone , regardless of ability, would face in CT (e.g., the impact of emotion and bias). Nevertheless, it is recommended that future research further investigates the influence of such inadequacies in cognitive resources on CT.

2 There is also some research that suggests that emotion may mediate enhanced cognition ( Dolcos et al. 2011 , 2012 ). However, this discrepancy in findings may result from the types of emotion studied—such as task-relevant emotion and task-irrelevant emotion. The distinction between the two is important to consider in terms of, for example, the distinction between one’s general mood and feelings specific unto the topic under consideration. Though mood may play a role in the manner in which CT is conducted (e.g., making judgments about a topic one is passionate about may elicit positive or negative emotions that affect the thinker’s mood in some way), notably, this discussion focuses on task-relevant emotion and associated biases that negatively impact the CT process. This is also an important distinction because an individual may generally think critically about ‘important’ topics, but may fail to do so when faced with a cognitive task that requires CT with which the individual has a strong, emotional perspective (e.g., in terms of passion , as described above).

Critical Thinking & Why It’s So Important

Critical thinking is a cognitive skill with the power to unlock the full potential of your mind. In today’s rapidly evolving society, where information is abundant but discerning its validity is becoming increasingly challenging, the art of critical thinking has never been more crucial.

At Nichols College, we believe that cultivating strong critical thinking abilities is not just a pursuit for the academically inclined, but a fundamental necessity for individuals across all walks of life. Join us as we explore the significance of critical thinking and the remarkable impact it can have on your decision-making, problem-solving, and overall cognitive prowess.

Discover why our Graduate Certificate program in Advanced Critical Thinking and Decision Making is your gateway to becoming a perceptive and adept thinker, ready to tackle the complex challenges of today’s world with confidence and ingenuity.

What is critical thinking?

Critical thinking is a fundamental skill that allows individuals to analyze, evaluate, and interpret information objectively and rationally. It goes beyond merely accepting information at face value; instead, critical thinkers are equipped to delve deeper, question assumptions, and explore various perspectives before arriving at well-informed conclusions. This ability to think critically is highly valued across various domains, including education, business, and everyday life.

Benefits of using critical thinking

The countless advantages of critical thinking extend far beyond the realms of academia. For starters, critical thinking fosters superior decision-making by equipping individuals with the tools to weigh options, assess consequences, and arrive at better choices. Critical thinkers also benefit from heightened self-reflection, gaining a profound understanding of their own biases and areas for improvement.

Critical thinkers become well-informed individuals who can navigate the sea of information with discernment, adeptly identifying misinformation and unreliable sources. Furthermore, this invaluable skill enables creative problem-solving, allowing thinkers to craft innovative solutions to intricate challenges. Some of the most important benefits of using critical thinking include:

Better decision making

Critical thinkers excel at weighing pros and cons, considering alternatives, and anticipating potential consequences. This leads to more informed and effective decision-making processes, both in personal and professional realms.

Better self-reflection

By fostering a habit of introspection, critical thinkers become more self-aware, recognizing their own biases and limitations. This heightened self-awareness allows them to continually improve and adapt their thinking patterns.

Being well-informed

Critical thinkers actively seek out diverse sources of information, ensuring they have a comprehensive understanding of complex issues. This empowers them to engage in meaningful discussions and contribute constructively to their communities.

The ability to identify misinformation

In a world filled with misinformation, critical thinkers possess the skills to discern fact from fiction. They scrutinize sources, verify information, and avoid being misled by deceptive content.

Building creative problem solving skills

Critical thinking encourages innovative and outside-the-box problem-solving approaches. By considering multiple angles and challenging conventional ideas, critical thinkers arrive at inventive solutions to complex challenges.

What skills do critical thinkers have?

Critical thinkers possess a remarkable set of skills that elevate their cognitive abilities and enable them to approach complex issues with acuity. Embracing these skills empowers them to tackle challenges, unravel complexities, and make meaningful insights and well-informed decisions. Some of the most valuable skills critical thinkers have include:

Critical thinkers have a natural inclination to ask questions and explore topics in-depth. Their thirst for knowledge drives them to seek out answers and continually expand their understanding.

Proficient in conducting thorough research, critical thinkers gather information from reliable sources and assess its validity. They are skilled at distinguishing credible data from biased or unsubstantiated claims.

Pattern recognition

Critical thinkers recognize recurring patterns and connections between seemingly unrelated pieces of information. This allows them to draw meaningful insights and make well-founded predictions.

Bias identification

Having honed the ability to identify biases, critical thinkers remain open-minded and impartial in their assessments. They acknowledge their own biases and strive to approach each situation objectively.

How to use critical thinking skills in the workplace

In any work environment, critical thinking is a valuable asset that can enhance productivity and foster a more innovative and collaborative workplace. Employees with strong critical thinking skills contribute to problem-solving sessions, provide constructive feedback, and make informed decisions based on thorough analysis. By promoting critical thinking, organizations encourage employees to challenge assumptions, seek out novel solutions, and contribute to the overall growth and success of the company.

Examples of good critical thinking in action

The real-world application of critical thinking can be awe-inspiring, as it empowers individuals to approach various scenarios with astute judgment and creativity. In the business realm and with regard to project management, critical thinkers demonstrate their prowess by:

• Analyzing Market Trends : A marketing professional employs critical thinking skills to assess market trends, consumer behavior, and competitor strategies before devising a successful marketing campaign that aligns with the target audience’s needs.
• Problem-Solving in Project Management : A project manager utilizes critical thinking to identify potential roadblocks, consider alternative approaches, and ensure projects are executed efficiently and within budget.

Furthermore, critical thinkers shine in scientific research, meticulously evaluating data, and drawing evidence-based conclusions that contribute to groundbreaking discoveries. In everyday life, they navigate the digital landscape with discernment, identifying misinformation and making informed decisions about their health, finances, and general well-being. These examples illustrate the power of critical thinking to transform not only individual lives but also entire industries, making it an indispensable skill in the pursuit of success and progress.

Recent events show that there has never been a more crucial time for critical thinking. A global onslaught of misinformation, social media saturation, partisan politics, and science skepticism continuously challenge how information is shared, understood, and how it influences the decisions people make.

Research from the Reboot Foundation and others show that an overwhelming majority of the population recognizes the importance of critical thinking skills in today’s modern society. From parents to employers, there is near unanimous support for the teaching of critical skills in American classrooms, yet new national survey data shows schools may not be teaching those skills often enough.

A new Reboot paper, Teaching Critical Thinking in K-12: When There’s A Will But Not Always A Way , examines the U.S. Department of Education’s National Assessment of Educational Progress (NAEP) and found that the teaching of critical thinking skills is inconsistent across states and tends to drop as students get older.

Among some of the key findings from NAEP:

• While 86 percent of 4th grade teachers said they put “quite a bit” or “a lot of emphasis” on deductive reasoning, that figure fell to only 39 percent of teachers in 8th grade. Deductive reasoning is one of the key skills in critical thinking, as it requires students to take a logical approach to turning general ideas into specific conclusions.
• At the state level, the analysis found that only seven states had at least 50 percent of their 8th grade teachers report that they place “quite a bit or a lot of emphasis” on teaching their students to engage in deductive reasoning.

While the numbers themselves are cause for concern, the age range at which these statistics are being reported is equally concerning. Research shows that while critical thinking skills can be learned at any stage of life, the teen years are an opportune time to engage young people as their brains are developing strong cognitive abilities.

These years are exactly when students should be building a strong foundation of critical thinking competencies that can last a lifetime. Developmental psychologists have noted that beginning at around age 13, adolescents can begin to acquire and apply formal logical rules and processes, if they are shown how. Yet the data shows that schools are largely failing to capitalize on this period, despite a desire by many educators to do so.

Per NAEP, nearly 90% of 4th grade teachers nationally said they put “quite a bit” or “a lot of emphasis” on deductive reasoning, only for that figure to fall to less than 40% of teachers in 8th grade – what issues are contributing to the drastic drop?

In 2020, Reboot surveyed teachers and found that many teachers harbored misconceptions about how to best teach critical thinking. The survey found that, among teachers, 42 percent reported that students should learn basic facts first, then engage in critical thinking practice, while an additional 16 percent said that they believed basic facts and critical thinking should be taught separately. This line of thinking is wrong, as research strongly suggests that critical thinking skills are best acquired in combination with the teaching of basic facts in a subject area.

This commonly-held misconception about when and how to teach critical thinking skills might be a clue as to why deductive reasoning instruction seems to tail off as students get older and take more specialized, content-driven classes. This might be made worse by the fact that eighth grade is a crucial year for many schools to show success under their state accountability measures.

In many states, students cannot move on to high school if they fail state exams in eighth grade. And things such as teacher pay, school funding and other “high-stakes” accountability measures often hinge on student performance in that grade. This pressure forces schools and teachers to focus on preparing their eighth graders for state exams in lieu of a more well-rounded educational experience. Indeed, our 2020 survey of teachers revealed that 55 percent believed that the emphasis on standardized testing made it more difficult to incorporate critical thinking instruction in their classrooms.

Reboot and others are working to identify ways teachers can implement critical thinking skills education into their curriculums more simply and efficiently. Among the stepping stones toward broader adoption are:

• A shared standard or consensus around critical thinking education that could contribute to more uniform and equitable teaching of these key skills nationwide.
• An easier way to broach critical thinking for a wide-ranging group of students. New research by Reboot and researchers from Indiana University explores innovative, inexpensive and scalable ways to teach critical thinking skills. The research found that educators and others can teach and hone essential critical thinking skills using a simple method that is easy to implement across diverse groups of students.

So even as the recent data from NAEP is disappointing on skills like deductive reasoning, it also shows where improvement needs to occur. What remains to be seen is the nation’s commitment to advancing critical thinking skills and its support for the educators, administrators and stakeholders working to knock down the challenges being faced. As NAEP and other surveys show, there is indeed a will to move forward with critical thinking skills education among teachers. Dedicated resources and consistent collaboration will be crucial to finding “the way.”

Why Is Critical Thinking Important? A Survival Guide

Updated: June 19, 2024

Published: April 2, 2020

Why is critical thinking important? The decisions that you make affect your quality of life. And if you want to ensure that you live your best, most successful and happy life, you’re going to want to make conscious choices. That can be done with a simple thing known as critical thinking. Here’s how to improve your critical thinking skills and make decisions that you won’t regret.

What Is Critical Thinking?

You’ve surely heard of critical thinking, but you might not be entirely sure what it really means, and that’s because there are many definitions. For the most part, however, we think of critical thinking as the process of analyzing facts in order to form a judgment. Basically, it’s thinking about thinking.

How Has The Definition Evolved Over Time?

The first time critical thinking was documented is believed to be in the teachings of Socrates , recorded by Plato. But throughout history, the definition has changed.

Today it is best understood by philosophers and psychologists and it’s believed to be a highly complex concept. Some insightful modern-day critical thinking definitions include :

• “Reasonable, reflective thinking that is focused on deciding what to believe or do.”
• “Deciding what’s true and what you should do.”

The Importance Of Critical Thinking

Why is critical thinking important? Good question! Here are a few undeniable reasons why it’s crucial to have these skills.

1. Critical Thinking Is Universal

Critical thinking is a domain-general thinking skill. What does this mean? It means that no matter what path or profession you pursue, these skills will always be relevant and will always be beneficial to your success. They are not specific to any field.

2. Crucial For The Economy

Our future depends on technology, information, and innovation. Critical thinking is needed for our fast-growing economies, to solve problems as quickly and as effectively as possible.

3. Improves Language & Presentation Skills

In order to best express ourselves, we need to know how to think clearly and systematically — meaning practice critical thinking! Critical thinking also means knowing how to break down texts, and in turn, improve our ability to comprehend.

4. Promotes Creativity

By practicing critical thinking, we are allowing ourselves not only to solve problems but also to come up with new and creative ideas to do so. Critical thinking allows us to analyze these ideas and adjust them accordingly.

5. Important For Self-Reflection

Without critical thinking, how can we really live a meaningful life? We need this skill to self-reflect and justify our ways of life and opinions. Critical thinking provides us with the tools to evaluate ourselves in the way that we need to.

6. The Basis Of Science & Democracy

In order to have a democracy and to prove scientific facts, we need critical thinking in the world. Theories must be backed up with knowledge. In order for a society to effectively function, its citizens need to establish opinions about what’s right and wrong (by using critical thinking!).

Benefits Of Critical Thinking

We know that critical thinking is good for society as a whole, but what are some benefits of critical thinking on an individual level? Why is critical thinking important for us?

1. Key For Career Success

Critical thinking is crucial for many career paths. Not just for scientists, but lawyers , doctors, reporters, engineers , accountants, and analysts (among many others) all have to use critical thinking in their positions. In fact, according to the World Economic Forum, critical thinking is one of the most desirable skills to have in the workforce, as it helps analyze information, think outside the box, solve problems with innovative solutions, and plan systematically.

2. Better Decision Making

There’s no doubt about it — critical thinkers make the best choices. Critical thinking helps us deal with everyday problems as they come our way, and very often this thought process is even done subconsciously. It helps us think independently and trust our gut feeling.

3. Can Make You Happier!

While this often goes unnoticed, being in touch with yourself and having a deep understanding of why you think the way you think can really make you happier. Critical thinking can help you better understand yourself, and in turn, help you avoid any kind of negative or limiting beliefs, and focus more on your strengths. Being able to share your thoughts can increase your quality of life.

4. Form Well-Informed Opinions

There is no shortage of information coming at us from all angles. And that’s exactly why we need to use our critical thinking skills and decide for ourselves what to believe. Critical thinking allows us to ensure that our opinions are based on the facts, and help us sort through all that extra noise.

5. Better Citizens

One of the most inspiring critical thinking quotes is by former US president Thomas Jefferson: “An educated citizenry is a vital requisite for our survival as a free people.” What Jefferson is stressing to us here is that critical thinkers make better citizens, as they are able to see the entire picture without getting sucked into biases and propaganda.

6. Improves Relationships

While you may be convinced that being a critical thinker is bound to cause you problems in relationships, this really couldn’t be less true! Being a critical thinker can allow you to better understand the perspective of others, and can help you become more open-minded towards different views.

7. Promotes Curiosity

Critical thinkers are constantly curious about all kinds of things in life, and tend to have a wide range of interests. Critical thinking means constantly asking questions and wanting to know more, about why, what, who, where, when, and everything else that can help them make sense of a situation or concept, never taking anything at face value.

8. Allows For Creativity

Critical thinkers are also highly creative thinkers, and see themselves as limitless when it comes to possibilities. They are constantly looking to take things further, which is crucial in the workforce.

9. Enhances Problem Solving Skills

Those with critical thinking skills tend to solve problems as part of their natural instinct. Critical thinkers are patient and committed to solving the problem, similar to Albert Einstein, one of the best critical thinking examples, who said “It’s not that I’m so smart; it’s just that I stay with problems longer.” Critical thinkers’ enhanced problem-solving skills makes them better at their jobs and better at solving the world’s biggest problems. Like Einstein, they have the potential to literally change the world.

10. An Activity For The Mind

Just like our muscles, in order for them to be strong, our mind also needs to be exercised and challenged. It’s safe to say that critical thinking is almost like an activity for the mind — and it needs to be practiced. Critical thinking encourages the development of many crucial skills such as logical thinking, decision making, and open-mindness.

11. Creates Independence

When we think critically, we think on our own as we trust ourselves more. Critical thinking is key to creating independence, and encouraging students to make their own decisions and form their own opinions.

12. Crucial Life Skill

Critical thinking is crucial not just for learning, but for life overall! Education isn’t just a way to prepare ourselves for life, but it’s pretty much life itself. Learning is a lifelong process that we go through each and every day.

How to Think Critically

Now that you know the benefits of thinking critically, how do you actually do it?

How To Improve Your Critical Thinking

• Define Your Question: When it comes to critical thinking, it’s important to always keep your goal in mind. Know what you’re trying to achieve, and then figure out how to best get there.
• Gather Reliable Information: Make sure that you’re using sources you can trust — biases aside. That’s how a real critical thinker operates!
• Ask The Right Questions: We all know the importance of questions, but be sure that you’re asking the right questions that are going to get you to your answer.
• Look Short & Long Term: When coming up with solutions, think about both the short- and long-term consequences. Both of them are significant in the equation.
• Explore All Sides: There is never just one simple answer, and nothing is black or white. Explore all options and think outside of the box before you come to any conclusions.

How Is Critical Thinking Developed At School?

Critical thinking is developed in nearly everything we do. However, much of this important skill is encouraged to be practiced at school, and rightfully so! Critical thinking goes beyond just thinking clearly — it’s also about thinking for yourself.

When a teacher asks a question in class, students are given the chance to answer for themselves and think critically about what they learned and what they believe to be accurate. When students work in groups and are forced to engage in discussion, this is also a great chance to expand their thinking and use their critical thinking skills.

How Does Critical Thinking Apply To Your Career?

Once you’ve finished school and entered the workforce, your critical thinking journey only expands and grows from here!

Impress Your Employer

Employers value employees who are critical thinkers, ask questions, offer creative ideas, and are always ready to offer innovation against the competition. No matter what your position or role in a company may be, critical thinking will always give you the power to stand out and make a difference.

Careers That Require Critical Thinking

Some of many examples of careers that require critical thinking include:

• Human resources specialist
• Marketing associate
• Business analyst

Truth be told however, it’s probably harder to come up with a professional field that doesn’t require any critical thinking!

What is someone with critical thinking skills capable of doing.

Someone with critical thinking skills is able to think rationally and clearly about what they should or not believe. They are capable of engaging in their own thoughts, and doing some reflection in order to come to a well-informed conclusion.

A critical thinker understands the connections between ideas, and is able to construct arguments based on facts, as well as find mistakes in reasoning.

The Process Of Critical Thinking

The process of critical thinking is highly systematic.

What Are Your Goals?

Critical thinking starts by defining your goals, and knowing what you are ultimately trying to achieve.

Once you know what you are trying to conclude, you can foresee your solution to the problem and play it out in your head from all perspectives.

What Does The Future Of Critical Thinking Hold?

The future of critical thinking is the equivalent of the future of jobs. In 2020, critical thinking was ranked as the 2nd top skill (following complex problem solving) by the World Economic Forum .

We are dealing with constant unprecedented changes, and what success is today, might not be considered success tomorrow — making critical thinking a key skill for the future workforce.

Why Is Critical Thinking So Important?

Why is critical thinking important? Critical thinking is more than just important! It’s one of the most crucial cognitive skills one can develop.

By practicing well-thought-out thinking, both your thoughts and decisions can make a positive change in your life, on both a professional and personal level. You can hugely improve your life by working on your critical thinking skills as often as you can.

The blood microbiome is probably not real.

• Add to calendar
• Tweet Widget

Up until recently, if bacteria were detected in your blood you would be in a world of trouble. Blood was long considered to be sterile, meaning free of viable microorganisms like bacteria. When disease-causing bacteria spread to the blood, they can cause a life-threatening septic shock.

But the use of DNA sequencing technology has allowed researchers to more easily detect something that had been reported as early as the late 1960s: bacteria can be found in the blood and not cause disease.

As we begin to map out and understand the complex microbial ecosystem that lives in our gut and elsewhere in the body, we contemplate an important question: is there such a thing as a blood microbiome?

Detecting a fingerprint in the blood

Our large intestine is not sterile; it is teeming with bacteria. But there are parts of the body that were long thought to be devoid of microorganisms. The brain. Bones. A variety of internal fluids, like our synovial fluid and peritoneal fluid. And, importantly, the blood.

Blood is made up of a liquid called plasma filled with red blood cells, whose main function is to carry oxygen to our cells. It also transports white blood cells, important to monitor for and fight off infections, as well as platelets, involved in clotting. 

In the 1960s, a team of Italian researchers published  multiple papers  describing “mycoplasm-like forms”—meaning shapes that look like a particular type of bacteria that often contaminate cells cultured in the lab—in the blood of healthy people. This finding was confirmed in 1977 by a different team, which reported that  four out of the 60 blood samples  they had drawn from healthy volunteers showed bacteria growing in them. These types of tests, however, were rudimentary compared to what we have access to now. In the 2000s, they were mostly supplanted by DNA testing.

While we can sequence the entire DNA of any bacteria found in the blood, the technique most often used is 16S rRNA gene sequencing. I have always admired physicists’ penchant for quirky names: gluons, neutrinos, and charm quarks. Molecular biologists, by comparison, tend to be more sober. Yes, we have genes like  Sonic hedgehog  and proteins called scramblases; usually, though, we have to contend with the dryness of “16S rRNA.” You see, RNA is a molecule with many uses. Messenger RNA (or mRNA) acts as a disposable copy of a gene, a template for the production of a specific protein. Transfer RNA (or tRNA) actually brings the building blocks of a protein to where they are being assembled. And ribosomal RNA (or rRNA) is the main component of the giant protein factories in our cells known as ribosomes. One of its subunits is made up of, among others, a particular string of RNA known as the 16S rRNA.

The cool thing about the gene that codes for this 16S rRNA molecule is that it is very old and it mutates at a slow rate. By reading its precise sequence, scientists can tell which species it belongs to. Most of the studies of the putative blood microbiome use this technique to tell which species of bacteria are present in the blood being tested. The limitation of this test, however, is that dead bacteria have DNA too. The fact that DNA from the 16S rRNA gene of a precise bacterial species was detected in someone’s blood does not mean these bacteria were alive. For there to be a microbiome in the blood, these microorganisms need to live.

Which brings us to another important point of discussion. In order for scientists to agree that a blood microbiome exists, they first need to decide on the definition of a microbiome, and this is still a point of contention. In 2020, while companies were more than happy to sell hyped-up services testing your gut microbiome and claiming to interpret what it meant for your health, actual experts in the field met to agree on just what the word meant. “We are lacking,” they  wrote , “a clear commonly agreed definition of the term ‘microbiome’.” For example, do viruses qualify? A microbiome implies life but viruses live on the edge, pun intended: they have the genetic blueprint for life yet they cannot reproduce on their own.

These experts proposed that the word “microbiome” should refer to the sum of two things: the microbiota, meaning the living microorganisms themselves, and their theatre of activity. It’s like saying that the Earth is not simply the life forms it houses, but also all of their individual components, and the traces they leave behind, and the environmental conditions in which they thrive or die. The microbiome is made up of bacteria and other microorganisms, yes, but also their proteins, lipids, sugars, and DNA and RNA molecules, as well as the signalling molecules and toxins that get exchanged within their theatre. (This is where viruses were sorted, by the way: not as part of the living microbiota but as belonging to the theatre of activity of the microbiome.)

The microbiome is a community, and this community has a distinct habitat.

So, what does the evidence say? Is our blood truly host to a thriving community of microorganisms or is something else going on?

Transient and sporadic

Initial studies of the alleged blood microbiome were  small . The amounts of bacteria that were being reported based on DNA sequencing were tiny. If this microbiome existed, it seemed sparse, more  “asteroid field in real life”  than “asteroid field in the movies.”

An issue looming over this early research is that of contamination. If bacteria are detected in a blood sample, were they really in the blood… or did they contaminate supplies along the way? When blood is drawn, the skin, which has its own microbiome, is punctured. The area is usually swabbed with alcohol to kill bacteria, and the supplies used should be sterile, but suffice to say that from the blood draw to the DNA extraction to the DNA amplification to the sequencing of this DNA, bacteria can be introduced into the system. In fact, it is such common knowledge that certain bacteria are found inside of the laboratory kits used by scientists that this ecosystem has its own name: the kitome. One way to rule out these contaminants is to simultaneously run negative controls alongside samples every step of the way, to make sure that these negative controls are indeed free of bacteria. But early papers rarely reported when controls were used.

Last year, results from what purports to be the largest study ever into the question of whether the blood microbiome exists were  published in  Nature Microbiology . A total of 9,770 healthy individuals were tested. The conclusion? Yes, some bacteria could be found in their blood, but the evidence contradicted the claim of an ecosystem. In 84% of the samples tested, no bacteria were detected. In most of the other samples, only one species was found. In an ecosystem, you would expect to see species appearing together repeatedly, but this was not the case here. And the species they found most often in their samples were known to contaminate these types of laboratory experiments.

So, what were the few bacteria found in the blood and not recognized as contaminants doing there in the first place if they were not part of a healthy microbiome? The authors lean toward an alternative explanation that had been floated for many years: these bacteria are transient. They end up in the blood from other parts of the body, either because of some minor leak or through their active transportation into the blood by agents such as dendritic cells. Like pedestrians wandering off onto the highway, these bacteria do not normally live in the blood but they can be seen there when we look at the right moment.

Putting the diagnostic cart before the horse

This blood microbiome story could end here and simply be an interesting example of scientific research homing in on a curious finding, testing a hypothesis, and ultimately refuting it (or at the very least providing strong evidence against it). But given the incentives of modern research and the social-media spotlight cast on the academic literature, there are two slightly worrying angles here that merit discussion.

Scientists are more and more incentivized to find practical applications for their research. It’s not enough, for example, to study bacteria that survive at incredibly high temperatures; we must be assured that the  DNA replication enzyme  these bacteria possess will one day be used in laboratories all over the world to conduct research, identify criminals, and test samples for the presence of a pandemic-causing coronavirus.

In researching this topic, I came across many papers claiming the existence of “blood microbiome signatures” for certain diseases that are not known to be infectious. We are thus not talking about infections leaking in the blood and causing sepsis. I saw reports of signatures for  cardiovascular disease ,  liver disease ,  heart attacks , even for  gastrointestinal disease  in dogs .  The idea is that these signatures could soon be turned into (profitable) diagnostic tests. The problem, of course, is that these studies are based on the hypothesis that a blood microbiome is real; that its equilibrium can be affected by disease; and that these changes can be reliably detected and interpreted.

But if the blood microbiome is imaginary, we are just chasing ghosts. This is not unlike the time that scientists were publishing signatures of microRNAs in the blood for every possible cancer. When I looked at the published literature in grad school, I realized that the multiple signatures reported for a single cancer  barely overlapped . They were just chance findings. Compare enough variables in a small sample set and you will find what appears to be an association.

My second concern is that the transitory leakage of bacteria into the blood, as evidenced by the recent  Nature Microbiology  paper, will be used as confirmation of a pseudoscientific entity: leaky gut syndrome. At the end of their paper, the researchers  hypothesize  that these bacteria end up in the blood because the integrity of certain barriers in the body are compromised during disease or during periods of stress. The “net” in our gut gets a bit porous, and some of our colon’s bacteria end up in circulation, though they are not causing disease as far as we can tell. A form of leaky gut is known to exist  in certain intestinal diseases , likely to be a consequence and not a cause. But leaky gut syndrome, favoured by non-evidence-based practitioners, does not appear to be real, yet many websites portray it as the one true cause of all diseases, a real epidemic. Nuanced scientific findings have a history of being stolen, distorted, and toyed with by fake doctors to give credence to their pet theories. Though I have yet to see examples of it, I suspect work done on this hypothesized blood microbiome will similarly get weaponized.

You have been warned.

Take-home message: - Our blood was long considered to be sterile, meaning free of viable microbes, unless a dangerous infection leaked into it, causing sepsis - Studies have provided evidence for the presence of bacteria in the blood of some healthy humans, leading to the hypothesis that, much like in our gut, our blood is host to a microbiome - The largest study ever done on the topic provided strong evidence against this hypothesis. It seems that when non-disease-causing bacteria find themselves in our blood, it is temporary and occasional

Fall 2024 Semester

Undergraduate courses.

Composition courses that offer many sections (ENGL 101, 201, 277 and 379) are not listed on this schedule unless they are tailored to specific thematic content or particularly appropriate for specific programs and majors.

• 100-200 level

ENGL 151.S01: Introduction to English Studies

Tuesday and Thursday, 11 a.m.-12:15 p.m.

Sharon Smith

ENGL 151 serves as an introduction to both the English major and the discipline of English studies. In this class, you will develop the thinking, reading, writing and research practices that define both the major and the discipline. Much of the semester will be devoted to honing your literary analysis skills, and we will study and discuss texts from several different genres—poetry, short fiction, the novel, drama and film—as well as some literary criticism. As we do so, we will explore the language of the discipline, and you will learn a variety of key literary terms and concepts. In addition, you will develop your skills as both a writer and researcher within the discipline of English.

ENGL 201.ST1 Composition II: The Mind/Body Connection

In this section of English 201, students will use research and writing to learn more about problems that are important to them and articulate ways to address those problems. The course will focus specifically on issues related to the mind, the body and the relationship between them. The topics we will discuss during the course will include the correlation between social media and body image; the efficacy of sex education programs; the degree to which beliefs about race and gender influence school dress codes; and the unique mental and physical challenges faced by college students today. In this course, you will be learning about different approaches to argumentation, analyzing the arguments of others and constructing your own arguments. At the same time, you will be honing your skills as a researcher and developing your abilities as a persuasive and effective writer.

ENGL 201.S10 Composition II: Environmental Writing   

Monday/Wednesday/Friday 1-1:50 p.m.

Gwen Horsley

English 201 will help students develop the ability to think critically and analytically and to write effectively for other university courses and careers. This course will provide opportunities to develop analytical skills that will help students become critical readers and effective writers. Specifically, in this class, students will:

• Focus on the relationships between world environments, land, animals and humankind.
• Read various essays by environmental, conservational and regional authors.
• Produce student writings. 

Students will improve their writing skills by reading essays and applying techniques they witness in others’ work and those learned in class. This class is also a course in logical and creative thought. Students will write about humankind’s place in the world and our influence on the land and animals, places that hold special meaning to them or have influenced their lives and stories of their own families and their places and passions in the world. Students will practice writing in an informed and persuasive manner, in language that engages and enlivens readers by using vivid verbs and avoiding unnecessary passives, nominalizations and expletive constructions.

Students will prepare writing assignments based on readings and discussions of essays included in "Literature and the Environment " and other sources. They may use "The St. Martin’s Handbook," as well as other sources, to review grammar, punctuation, mechanics and usage as needed.

ENGL 201.13 Composition II: Writing the Environment

Tuesday and Thursday 9:30-10:45 a.m.

Paul Baggett

For generations, environmentalists have relied on the power of prose to change the minds and habits of their contemporaries. In the wake of fires, floods, storms and droughts, environmental writing has gained a new sense of urgency, with authors joining activists in their efforts to educate the public about the grim realities of climate change. But do they make a difference? Have reports of present and future disasters so saturated our airwaves that we no longer hear them? How do writers make us care about the planet amidst all the noise? In this course, students will examine the various rhetorical strategies employed by some of today’s leading environmental writers and filmmakers. And while analyzing their different arguments, students also will strengthen their own strategies of argumentation as they research and develop essays that explore a range of environmental concerns.

ENGL 201 Composition II: Food Writing

S17 Tuesday and Thursday 12:30-1:45 p.m.

S18 Tuesday and Thursday 2-3:15 p.m.

Jodi Andrews

In this composition class, students will critically analyze essays about food, food systems and environments, food cultures, the intersections of personal choice, market forces and policy and the values underneath these forces. Students will learn to better read like writers, noting authors’ purpose, audience organizational moves, sentence-level punctuation and diction. We will read a variety of essays including research-intensive arguments and personal narratives which intersect with one of our most primal needs as humans: food consumption. Students will rhetorically analyze texts, conduct advanced research, reflect on the writing process and write essays utilizing intentional rhetorical strategies. Through doing this work, students will practice the writing moves valued in every discipline: argument, evidence, concision, engaging prose and the essential research skills for the 21st century.

ENGL 221.S01 British Literature I

Michael S. Nagy

English 221 is a survey of early British literature from its inception in the Old English period with works such as "Beowulf" and the “Battle of Maldon,” through the Middle Ages and the incomparable writings of Geoffrey Chaucer and the Gawain - poet, to the Renaissance and beyond. Students will explore the historical and cultural contexts in which all assigned reading materials were written, and they will bring that information to bear on class discussion. Likely themes that this class will cover include heroism, humor, honor, religion, heresy and moral relativity. Students will write one research paper in this class and sit for two formal exams: a midterm covering everything up to that point in the semester, and a comprehensive final. Probable texts include the following:

ENGL 240.S01 Juvenile Literature Elementary-5th Grade

Monday, Wednesday and Friday noon-12:50 p.m.

April Myrick

A survey of the history of literature written for children and adolescents, and a consideration of the various types of juvenile literature. Text selection will focus on the themes of imagination and breaking boundaries.

ENGL 240.ST1 Juvenile Literature Elementary-5th Grade

Randi Anderson

In English 240 students will develop the skills to interpret and evaluate various genres of literature for juvenile readers. This particular section will focus on various works of literature at approximately the K-5 grade level. We will read a large range of works that fall into this category, as well as information on the history, development and genre of juvenile literature.

Readings for this course include classical works such as "Hatchet," "Little Women", "The Lion, the Witch and the Wardrobe" and "Brown Girl Dreaming," as well as newer works like "Storm in the Barn," "Anne Frank’s Diary: A Graphic Adaptation," "Lumberjanes," and a variety of picture books. These readings will be paired with chapters from "Reading Children’s Literature: A Critical Introduction " to help develop understanding of various genres, themes and concepts that are both related to juvenile literature and also present in our readings.

In addition to exposing students to various genres of writing (poetry, historical fiction, non-fiction, fantasy, picture books, graphic novels, etc.) this course will also allow students to engage in a discussion of larger themes present in these works such as censorship, race and gender. Students’ understanding of these works and concepts will be developed through readings, research, discussion posts, exams and writing assignments designed to get students to practice analyzing poetry, picture books, informational books and transitional/easy readers.

ENGL 241.S01: American Literature I

Tuesday and Thursday 12:30-1:45 p.m.

This course provides a broad, historical survey of American literature from the early colonial period to the Civil War. Ranging across historical periods and literary genres—including early accounts of contact and discovery, narratives of captivity and slavery, poetry of revolution, essays on gender equality and stories of industrial exploitation—this class examines how subjects such as colonialism, nationhood, religion, slavery, westward expansion, race, gender and democracy continue to influence how Americans see themselves and their society.

Required Texts

ENGL 283.S01 Introduction to Creative Writing

Steven Wingate

Students will explore the various forms of creative writing (fiction, nonfiction and poetry) not one at a time in a survey format—as if there were decisive walls of separation between then—but as intensely related genres that share much of their creative DNA. Through close reading and work on personal texts, students will address the decisions that writers in any genre must face on voice, rhetorical position, relationship to audience, etc. Students will produce and revise portfolios of original creative work developed from prompts and research. This course fulfills the same SGR #2 requirements ENGL 201; note that the course will involve a research project. Successful completion of ENGL 101 (including by test or dual credit) is a prerequisite.

ENGL 283.S02 Introduction to Creative Writing

Jodilyn Andrews

This course introduces students to the craft of writing, with readings and practice in at least two genres (including fiction, poetry and drama).

ENGL 283.ST1 Introduction to Creative Writing

Amber Jensen, M.A., M.F.A.

This course explores creative writing as a way of encountering the world, research as a component of the creative writing process, elements of craft and their rhetorical effect and drafting, workshop and revision as integral parts of writing polished literary creative work. Student writers will engage in the research practices that inform the writing of literature and in the composing strategies and writing process writers use to create literary texts. Through their reading and writing of fiction, poetry and creative nonfiction, students will learn about craft elements, find examples of those craft elements in published works and apply these elements in their own creative work, developed through weekly writing activities, small group and large group workshop and conferences with the instructor. Work will be submitted, along with a learning reflection and revision plan in each genre and will then be revised and submitted as a final portfolio at the end of the semester to demonstrate continued growth in the creation of polished literary writing.

AIS/ENGL 447.S01: American Indian Literature of the Present 

Thursdays 3-6 p.m.

This course introduces students to contemporary works by authors from various Indigenous nations. Students examine these works to enhance their historical understanding of Indigenous peoples, discover the variety of literary forms used by those who identify as Indigenous writers, and consider the cultural and political significance of these varieties of expression. Topics and questions to be explored include:

• Genre: What makes Indigenous literature indigenous?
• Political and Cultural Sovereignty: Why have an emphasis on tribal specificity and calls for “literary separatism” emerged in recent decades, and what are some of the critical conversations surrounding such particularized perspectives?
• Gender and Sexuality: What are the intersecting concerns of Indigenous Studies and Women, Gender and Sexuality Studies, and how might these research fields inform one another?
• Trans-Indigeneity: What might we learn by comparing works across different Indigenous traditions, and what challenges do such comparisons present?
• Aesthetics: How do Indigenous writers understand the dynamics between tradition and creativity?
• Visual Forms: What questions or concerns do visual representations (television and film) by or about Indigenous peoples present?

ENGL 472.S01: Film Criticism

Tuesdays 2-4:50 p.m.

Jason McEntee

Do you have an appreciation for, and enjoy watching, movies? Do you want to study movies in a genre-oriented format (such as those we typically call the Western, the screwball comedy, the science fiction or the crime/gangster, to name a few)? Do you want to explore the different critical approaches for talking and writing about movies (such as auteur, feminist, genre or reception)?

In this class, you will examine movies through viewing and defining different genres while, at the same time, studying and utilizing different styles of film criticism. You will share your discoveries in both class discussions and short writings. The final project will be a formal written piece of film criticism based on our work throughout the semester. The course satisfies requirements and electives for all English majors and minors, including both the Film Studies and Professional Writing minors. (Note: Viewing of movies outside of class required and may require rental and/or streaming service fees.)

ENGL 476.ST1: Fiction

In this workshop-based creative writing course, students will develop original fiction based on strong attention to the fundamentals of literary storytelling: full-bodied characters, robust story lines, palpable environments and unique voices. We will pay particular attention to process awareness, to the integrity of the sentence, and to authors' commitments to their characters and the places in which their stories unfold. Some workshop experience is helpful, as student peer critique will be an important element of the class.

ENGL 479.01 Capstone: The Gothic

Wednesday 3-5:50 p.m.

With the publication of Horace Walpole’s "The Castle of Otranto " in 1764, the Gothic officially came into being. Dark tales of physical violence and psychological terror, the Gothic incorporates elements such as distressed heroes and heroines pursued by tyrannical villains; gloomy estates with dark corridors, secret passageways and mysterious chambers; haunting dreams, troubling prophecies and disturbing premonitions; abduction, imprisonment and murder; and a varied assortment of corpses, apparitions and “monsters.” In this course, we will trace the development of Gothic literature—and some film—from the eighteenth-century to the present time. As we do so, we will consider how the Gothic engages philosophical beliefs about the beautiful and sublime; shapes psychological understandings of human beings’ encounters with horror, terror, the fantastic and the uncanny; and intervenes in the social and historical contexts in which it was written. We’ll consider, for example, how the Gothic undermines ideals related to domesticity and marriage through representations of domestic abuse, toxicity and gaslighting. In addition, we’ll discuss Gothic texts that center the injustices of slavery and racism. As many Gothic texts suggest, the true horrors of human existence often have less to do with inexplicable supernatural phenomena than with the realities of the world in which we live. 

ENGL 485.S01: Undergraduate Writing Center Learning Assistants 

Flexible Scheduling

Nathan Serfling

Since their beginnings in the 1920s and 30s, writing centers have come to serve numerous functions: as hubs for writing across the curriculum initiatives, sites to develop and deliver workshops and resource centers for faculty as well as students, among other functions. But the primary function of writing centers has necessarily and rightfully remained the tutoring of student writers. This course will immerse you in that function in two parts. During the first four weeks, you will explore writing center praxis—that is, the dialogic interplay of theory and practice related to writing center work. This part of the course will orient you to writing center history, key theoretical tenets and practical aspects of writing center tutoring. Once we have developed and practiced this foundation, you will begin work in the writing center as a tutor, responsible for assisting a wide variety of student clients with numerous writing tasks. Through this work, you will learn to actively engage with student clients in the revision of a text, respond to different student needs and abilities, work with a variety of writing tasks and rhetorical situations, and develop a richer sense of writing as a complex and negotiated social process.

Graduate Courses

Engl 572.s01: film criticism, engl 576.st1 fiction.

In this workshop-based creative writing course, students will develop original fiction based on strong attention to the fundamentals of literary storytelling: full-bodied characters, robust story lines, palpable environments and unique voices. We will pay particular attention to process awareness, to the integrity of the sentence and to authors' commitments to their characters and the places in which their stories unfold. Some workshop experience is helpful, as student peer critique will be an important element of the class.

ENGL 605.S01 Seminar in Teaching Composition

Thursdays 1-3:50 p.m.

This course will provide you with a foundation in the pedagogies and theories (and their attendant histories) of writing instruction, a foundation that will prepare you to teach your own writing courses at SDSU and elsewhere. As you will discover through our course, though, writing instruction does not come with any prescribed set of “best” practices. Rather, writing pedagogies stem from and continue to evolve because of various and largely unsettled conversations about what constitutes effective writing and effective writing instruction. Part of becoming a practicing writing instructor, then, is studying these conversations to develop a sense of what “good writing” and “effective writing instruction” might mean for you in our particular program and how you might adapt that understanding to different programs and contexts.

As we read about, discuss and research writing instruction, we will address a variety of practical and theoretical topics. The practical focus will allow us to attend to topics relevant to your immediate classroom practices: designing a curriculum and various types of assignments, delivering the course content and assessing student work, among others. Our theoretical topics will begin to reveal the underpinnings of these various practical matters, including their historical, rhetorical, social and political contexts. In other words, we will investigate the praxis—the dialogic interaction of practice and theory—of writing pedagogy. As a result, this course aims to prepare you not only as a writing teacher but also as a nascent writing studies/writing pedagogy scholar.

At the end of this course, you should be able to engage effectively in the classroom practices described above and participate in academic conversations about writing pedagogy, both orally and in writing. Assessment of these outcomes will be based primarily on the various writing assignments you submit and to a smaller degree on your participation in class discussions and activities.

ENGL 726.S01: The New Woman, 1880–1900s 

Thursdays 3–5:50 p.m.

Katherine Malone

This course explores the rise of the New Woman at the end of the nineteenth century. The label New Woman referred to independent women who rebelled against social conventions. Often depicted riding bicycles, smoking cigarettes and wearing masculine clothing, these early feminists challenged gender roles and sought broader opportunities for women’s employment and self-determination. We will read provocative fiction and nonfiction by New Women writers and their critics, including authors such as Sarah Grand, Mona Caird, George Egerton, Amy Levy, Ella Hepworth Dixon, Grant Allen and George Gissing. We will analyze these exciting texts through a range of critical lenses and within the historical context of imperialism, scientific and technological innovation, the growth of the periodical press and discourse about race, class and gender. In addition to writing an argumentative seminar paper, students will complete short research assignments and lead discussion.

ENGL 792.ST1 Women in War: Female Authors and Characters in Contemporary War Lit

In this course, we will explore the voices of female authors and characters in contemporary literature of war. Drawing from various literary theories, our readings and discussion will explore the contributions of these voices to the evolving literature of war through archetypal and feminist criticism. We will read a variety of short works (both theoretical and creative) and complete works such as (selections subject to change): "Eyes Right" by Tracy Crow, "Plenty of Time When We Get Home" by Kayla Williams, "You Know When the Men are Gone" by Siobhan Fallon, "Still, Come Home" by Katie Schultz and "The Fine Art of Camouflage" by Lauren Johnson.

Health Lesson: Learning About Bones

Information on this page is mapped to national science and health education standards and is for students in grades 4 through 6 who are learning about the human body. Teachers may also use these resources to inform their lesson plans.

On This Page

• For Students : Find all classroom materials and activities about bones

For Students

What would your body be like without bones ? Bones give your body shape, help you move, protect your organs, and more! On this page, you can learn about bones, what happens when they get hurt, and how to keep them healthy.

What are bones?

Bones are the tissues —groups of cells that work together—that make up your skeleton. Bones might remind you of dead things or fossils, but the bones in your body are alive. They grow and change all the time!

Bones keep your body healthy in many ways. They:

• Support and hold up your body . Without bones your body would be a squishy blob on the ground.
• Help you move . Muscles work together with bones to move your body around.
• Protect your organs . Some bones shield your organs from injury. For example, your ribs protect your heart and lungs, and your skull protects your brain.
• Make blood cells . Some types of bone have a jelly-like material inside called bone marrow (MEH-row) . New blood cells are made inside the bone marrow!
• Store energy . Some types of bone, like the leg bones, contain cells that store fat and release it when your body needs energy.
• Store minerals and vitamin D . Bones can store minerals like calcium and phosphorus, and vitamin D, and release them when your body needs them.  

What are bones made of?

Bones are made mostly of a protein called collagen (KAA-luh-jn) and a mineral called calcium phosphate (KAL-see-uhm FAA-sfayt) . Together, these materials make your bones strong and flexible.

Bones have three layers:

• The periosteum (peh-ree-ow-STEE-uhm) is a thin membrane covering the bone that contains nerves and blood vessels.
• Compact bone is the dense and hard outer layer of the bone that you see when you look at a skeleton.
• Cancellous (KAN-suh-luhs) bone is inside the compact bone. It is full of holes and looks a little like a sponge. Bone marrow fills in the holes of the sponge.

Bones are held together at the joints by ligaments (LI-guh-muhnts) , a type of tissue that is like a strong rubber band. Learn more about joints , which are made up of ligaments and other types of tissue.

Try this experiment at home to learn what makes bones strong and flexible at the same time! Be sure to wash your hands with soap and water after touching the bones!

How do bones grow?

As you get older and grow taller, your bones grow, too! There are special zones of bones that grow with you called growth plates .

Did You Know?

A baby is born with about 300 bones. Many of them eventually fuse (grow together) to form the 206 bones that adults have.

Bone tissue is constantly changing in a process called remodeling . All the time, old or damaged bone tissue is broken down, and new bone tissue is made to replace it. When you’re young, new bone is made faster than old bone is broken down, which means that your bones get denser and stronger. In most people, the amount of bone tissue in the skeleton peaks by their mid- to late 20s.

• The bone cells that break down old bone are called osteoclasts (AA-stee-uh-klasts) .
• The bone cells that make new bone are called osteoblasts (AA-stee-uh-blasts) .

As you age, old bone tissue is broken down faster than new bone is made. For some people, the bones become weaker and easier to break. This condition is called osteoporosis (aa-stee-ow-opr-OW-suhs) .

Doctors have special names for the ways bones can break. Learn about the different types of fractures with this activity !

What happens when bones break?

Broken bones are also called fractures (FRAK-chrz) . The break can go through only part of the bone or completely through it.

It hurts to break a bone! There might also be swelling and bruising. If you are injured and go to the doctor, the doctor may take pictures of your bone with x-rays to see if it is broken. If you do have a broken bone, the doctor may put on a cast, splint, or brace to keep the bone from moving around as it heals, and to make sure it heals correctly. Sometimes, bones move so much when they break that the doctor has to “set the bone”—put it back in the right place before putting a cast, splint, or brace on it.

How much force does it take to break a bone? Try this experiment at home with chicken bones to find out!

Most broken bones heal within a few months. First, your body forms a blood clot around the break to protect it and deliver the cells that will heal it. Next, a healing zone called a callus (KA-luhs) forms around the break. It joins the bones together. At first, the callus is soft, but it gets harder and stronger as the bone heals.

What is scoliosis ?

Your backbone, also called your spine, is actually made of many small bones called vertebrae (VUR-tuh-bray) that form a line. Scoliosis (skow-lee-OW-suhs) happens when the spine bones are curved instead of being straight.

Most of the time, people get scoliosis as pre-teens or teenagers. By going to the doctor and getting treated when needed, people with scoliosis can have healthy, active lives.

Small curves usually don’t cause problems. If a doctor notices you have a curved spine, they may just check it every once in a while, to make sure the curve doesn’t get worse. Really big curves or small curves that get worse can cause health problems. In these cases, doctors treat scoliosis with a back brace or surgery.

Doctors don’t know what causes scoliosis, but they do know that having a parent who had scoliosis makes it more likely that you will have it, too.

How can I help keep my bones healthy?

Avoid bone injuries..

Wear the right equipment to protect your bones. Always wear a helmet to protect your skull while biking, scootering, skateboarding, or skating. You can also wear elbow and knee pads to protect your arms and legs.

When playing sports like football, soccer, lacrosse, or ice hockey, always wear all the right equipment. Make sure the safety gear fits you, or else it might not do its job.

When you’re in the car, remember to buckle your seatbelt.

Get plenty of physical activity every day. Your bones respond to exercise by making new bone tissue, which helps keep them strong.

To keep bones healthy, do activities that put weight on your bones. Playing basketball, kickball, walking, jumping rope, and dancing are good examples.

Eat well to keep your bones healthy.

Calcium and vitamin D . Remember that bones are made of a mineral called calcium phosphate? To keep bones strong, you need to get that calcium from food or supplements . You can get calcium from milk, cheese, and yogurt. Leafy green vegetables like broccoli, brussels sprouts, and kale are also important sources of calcium.

Vitamin D helps your body absorb the calcium in the foods you eat. You can get vitamin D from certain foods , like eggs, fish, and special types of orange juice, milk, and cereals that have vitamin D added to them.

Eat a balanced diet . Try to eat a combination of fruits, vegetables, whole grains, lean protein, and low-fat dairy.  Eating a variety of foods and being active every day helps keep your body healthy and strong. While you need both muscle and fat for your body to work properly, in general, having more healthy muscle tissue helps keep your bones healthy.
