Writing an Introduction for a Scientific Paper

Dr. michelle harris, dr. janet batzli, biocore.

This section provides guidelines on how to construct a solid introduction to a scientific paper including background information, study question , biological rationale, hypothesis , and general approach . If the Introduction is done well, there should be no question in the reader’s mind why and on what basis you have posed a specific hypothesis.

Broad Question : based on an initial observation (e.g., “I see a lot of guppies close to the shore. Do guppies like living in shallow water?”). This observation of the natural world may inspire you to investigate background literature or your observation could be based on previous research by others or your own pilot study. Broad questions are not always included in your written text, but are essential for establishing the direction of your research.

Background Information : key issues, concepts, terminology, and definitions needed to understand the biological rationale for the experiment. It often includes a summary of findings from previous, relevant studies. Remember to cite references, be concise, and only include relevant information given your audience and your experimental design. Concisely summarized background information leads to the identification of specific scientific knowledge gaps that still exist. (e.g., “No studies to date have examined whether guppies do indeed spend more time in shallow water.”)

Testable Question : these questions are much more focused than the initial broad question, are specific to the knowledge gap identified, and can be addressed with data. (e.g., “Do guppies spend different amounts of time in water <1 meter deep as compared to their time in water that is >1 meter deep?”)

Biological Rationale : describes the purpose of your experiment distilling what is known and what is not known that defines the knowledge gap that you are addressing. The “BR” provides the logic for your hypothesis and experimental approach, describing the biological mechanism and assumptions that explain why your hypothesis should be true.

The biological rationale is based on your interpretation of the scientific literature, your personal observations, and the underlying assumptions you are making about how you think the system works. If you have written your biological rationale, your reader should see your hypothesis in your introduction section and say to themselves, “Of course, this hypothesis seems very logical based on the rationale presented.”

• A thorough rationale defines your assumptions about the system that have not been revealed in scientific literature or from previous systematic observation. These assumptions drive the direction of your specific hypothesis or general predictions.
• Defining the rationale is probably the most critical task for a writer, as it tells your reader why your research is biologically meaningful. It may help to think about the rationale as an answer to the questions— how is this investigation related to what we know, what assumptions am I making about what we don’t yet know, AND how will this experiment add to our knowledge? *There may or may not be broader implications for your study; be careful not to overstate these (see note on social justifications below).
• Expect to spend time and mental effort on this. You may have to do considerable digging into the scientific literature to define how your experiment fits into what is already known and why it is relevant to pursue.
• Be open to the possibility that as you work with and think about your data, you may develop a deeper, more accurate understanding of the experimental system. You may find the original rationale needs to be revised to reflect your new, more sophisticated understanding.
• As you progress through Biocore and upper level biology courses, your rationale should become more focused and matched with the level of study e ., cellular, biochemical, or physiological mechanisms that underlie the rationale. Achieving this type of understanding takes effort, but it will lead to better communication of your science.

***Special note on avoiding social justifications: You should not overemphasize the relevance of your experiment and the possible connections to large-scale processes. Be realistic and logical —do not overgeneralize or state grand implications that are not sensible given the structure of your experimental system. Not all science is easily applied to improving the human condition. Performing an investigation just for the sake of adding to our scientific knowledge (“pure or basic science”) is just as important as applied science. In fact, basic science often provides the foundation for applied studies.

Hypothesis / Predictions : specific prediction(s) that you will test during your experiment. For manipulative experiments, the hypothesis should include the independent variable (what you manipulate), the dependent variable(s) (what you measure), the organism or system , the direction of your results, and comparison to be made.

If you are doing a systematic observation , your hypothesis presents a variable or set of variables that you predict are important for helping you characterize the system as a whole, or predict differences between components/areas of the system that help you explain how the system functions or changes over time.

Experimental Approach : Briefly gives the reader a general sense of the experiment, the type of data it will yield, and the kind of conclusions you expect to obtain from the data. Do not confuse the experimental approach with the experimental protocol . The experimental protocol consists of the detailed step-by-step procedures and techniques used during the experiment that are to be reported in the Methods and Materials section.

Some Final Tips on Writing an Introduction

• As you progress through the Biocore sequence, for instance, from organismal level of Biocore 301/302 to the cellular level in Biocore 303/304, we expect the contents of your “Introduction” paragraphs to reflect the level of your coursework and previous writing experience. For example, in Biocore 304 (Cell Biology Lab) biological rationale should draw upon assumptions we are making about cellular and biochemical processes.
• Be Concise yet Specific: Remember to be concise and only include relevant information given your audience and your experimental design. As you write, keep asking, “Is this necessary information or is this irrelevant detail?” For example, if you are writing a paper claiming that a certain compound is a competitive inhibitor to the enzyme alkaline phosphatase and acts by binding to the active site, you need to explain (briefly) Michaelis-Menton kinetics and the meaning and significance of Km and Vmax. This explanation is not necessary if you are reporting the dependence of enzyme activity on pH because you do not need to measure Km and Vmax to get an estimate of enzyme activity.
• Another example: if you are writing a paper reporting an increase in Daphnia magna heart rate upon exposure to caffeine you need not describe the reproductive cycle of magna unless it is germane to your results and discussion. Be specific and concrete, especially when making introductory or summary statements.

Where Do You Discuss Pilot Studies? Many times it is important to do pilot studies to help you get familiar with your experimental system or to improve your experimental design. If your pilot study influences your biological rationale or hypothesis, you need to describe it in your Introduction. If your pilot study simply informs the logistics or techniques, but does not influence your rationale, then the description of your pilot study belongs in the Materials and Methods section.

The introduction leads the reader from a general subject area to a particular topic of inquiry. It establishes the scope, context, and significance of the research being conducted by summarizing current understanding and background information about the topic, stating the purpose of the work in the form of the research problem supported by a hypothesis or a set of questions, explaining briefly the methodological approach used to examine the research problem, highlighting the potential outcomes your study can reveal, and outlining the remaining structure and organization of the paper.

Importance of a Good Introduction

Think of the introduction as a mental road map that must answer for the reader these four questions:

• What was I studying?
• Why was this topic important to investigate?
• What did we know about this topic before I did this study?
• How will this study advance new knowledge or new ways of understanding?

According to Reyes, there are three overarching goals of a good introduction: 1) ensure that you summarize prior studies about the topic in a manner that lays a foundation for understanding the research problem; 2) explain how your study specifically addresses gaps in the literature, insufficient consideration of the topic, or other deficiency in the literature; and, 3) note the broader theoretical, empirical, and/or policy contributions and implications of your research.

A well-written introduction is important because, quite simply, you never get a second chance to make a good first impression. The opening paragraphs of your paper will provide your readers with their initial impressions about the logic of your argument, your writing style, the overall quality of your research, and, ultimately, the validity of your findings and conclusions. A vague, disorganized, or error-filled introduction will create a negative impression, whereas, a concise, engaging, and well-written introduction will lead your readers to think highly of your analytical skills, your writing style, and your research approach. All introductions should conclude with a brief paragraph that describes the organization of the rest of the paper.

Structure and Writing Style

I.  Structure and Approach

The introduction is the broad beginning of the paper that answers three important questions for the reader:

• What is this?
• Why should I read it?
• What do you want me to think about / consider doing / react to?

Think of the structure of the introduction as an inverted triangle of information that lays a foundation for understanding the research problem. Organize the information so as to present the more general aspects of the topic early in the introduction, then narrow your analysis to more specific topical information that provides context, finally arriving at your research problem and the rationale for studying it [often written as a series of key questions to be addressed or framed as a hypothesis or set of assumptions to be tested] and, whenever possible, a description of the potential outcomes your study can reveal.

These are general phases associated with writing an introduction: 1.  Establish an area to research by:

• Highlighting the importance of the topic, and/or
• Making general statements about the topic, and/or
• Presenting an overview on current research on the subject.

2.  Identify a research niche by:

• Opposing an existing assumption, and/or
• Revealing a gap in existing research, and/or
• Formulating a research question or problem, and/or
• Continuing a disciplinary tradition.

3.  Place your research within the research niche by:

• Stating the intent of your study,
• Outlining the key characteristics of your study,
• Describing important results, and
• Giving a brief overview of the structure of the paper.

NOTE:   It is often useful to review the introduction late in the writing process. This is appropriate because outcomes are unknown until you've completed the study. After you complete writing the body of the paper, go back and review introductory descriptions of the structure of the paper, the method of data gathering, the reporting and analysis of results, and the conclusion. Reviewing and, if necessary, rewriting the introduction ensures that it correctly matches the overall structure of your final paper.

II.  Delimitations of the Study

Delimitations refer to those characteristics that limit the scope and define the conceptual boundaries of your research . This is determined by the conscious exclusionary and inclusionary decisions you make about how to investigate the research problem. In other words, not only should you tell the reader what it is you are studying and why, but you must also acknowledge why you rejected alternative approaches that could have been used to examine the topic.

Obviously, the first limiting step was the choice of research problem itself. However, implicit are other, related problems that could have been chosen but were rejected. These should be noted in the conclusion of your introduction. For example, a delimitating statement could read, "Although many factors can be understood to impact the likelihood young people will vote, this study will focus on socioeconomic factors related to the need to work full-time while in school." The point is not to document every possible delimiting factor, but to highlight why previously researched issues related to the topic were not addressed.

Examples of delimitating choices would be:

• The key aims and objectives of your study,
• The research questions that you address,
• The variables of interest [i.e., the various factors and features of the phenomenon being studied],
• The method(s) of investigation,
• The time period your study covers, and
• Any relevant alternative theoretical frameworks that could have been adopted.

Review each of these decisions. Not only do you clearly establish what you intend to accomplish in your research, but you should also include a declaration of what the study does not intend to cover. In the latter case, your exclusionary decisions should be based upon criteria understood as, "not interesting"; "not directly relevant"; “too problematic because..."; "not feasible," and the like. Make this reasoning explicit!

NOTE:   Delimitations refer to the initial choices made about the broader, overall design of your study and should not be confused with documenting the limitations of your study discovered after the research has been completed.

ANOTHER NOTE: Do not view delimitating statements as admitting to an inherent failing or shortcoming in your research. They are an accepted element of academic writing intended to keep the reader focused on the research problem by explicitly defining the conceptual boundaries and scope of your study. It addresses any critical questions in the reader's mind of, "Why the hell didn't the author examine this?"

III.  The Narrative Flow

Issues to keep in mind that will help the narrative flow in your introduction :

• Your introduction should clearly identify the subject area of interest . A simple strategy to follow is to use key words from your title in the first few sentences of the introduction. This will help focus the introduction on the topic at the appropriate level and ensures that you get to the subject matter quickly without losing focus, or discussing information that is too general.
• Establish context by providing a brief and balanced review of the pertinent published literature that is available on the subject. The key is to summarize for the reader what is known about the specific research problem before you did your analysis. This part of your introduction should not represent a comprehensive literature review--that comes next. It consists of a general review of the important, foundational research literature [with citations] that establishes a foundation for understanding key elements of the research problem. See the drop-down menu under this tab for " Background Information " regarding types of contexts.
• Clearly state the hypothesis that you investigated . When you are first learning to write in this format it is okay, and actually preferable, to use a past statement like, "The purpose of this study was to...." or "We investigated three possible mechanisms to explain the...."
• Why did you choose this kind of research study or design? Provide a clear statement of the rationale for your approach to the problem studied. This will usually follow your statement of purpose in the last paragraph of the introduction.

IV.  Engaging the Reader

A research problem in the social sciences can come across as dry and uninteresting to anyone unfamiliar with the topic . Therefore, one of the goals of your introduction is to make readers want to read your paper. Here are several strategies you can use to grab the reader's attention:

• Open with a compelling story . Almost all research problems in the social sciences, no matter how obscure or esoteric , are really about the lives of people. Telling a story that humanizes an issue can help illuminate the significance of the problem and help the reader empathize with those affected by the condition being studied.
• Include a strong quotation or a vivid, perhaps unexpected, anecdote . During your review of the literature, make note of any quotes or anecdotes that grab your attention because they can used in your introduction to highlight the research problem in a captivating way.
• Pose a provocative or thought-provoking question . Your research problem should be framed by a set of questions to be addressed or hypotheses to be tested. However, a provocative question can be presented in the beginning of your introduction that challenges an existing assumption or compels the reader to consider an alternative viewpoint that helps establish the significance of your study. 
• Describe a puzzling scenario or incongruity . This involves highlighting an interesting quandary concerning the research problem or describing contradictory findings from prior studies about a topic. Posing what is essentially an unresolved intellectual riddle about the problem can engage the reader's interest in the study.
• Cite a stirring example or case study that illustrates why the research problem is important . Draw upon the findings of others to demonstrate the significance of the problem and to describe how your study builds upon or offers alternatives ways of investigating this prior research.

NOTE:   It is important that you choose only one of the suggested strategies for engaging your readers. This avoids giving an impression that your paper is more flash than substance and does not distract from the substance of your study.

Writing Tip

Avoid the "Dictionary" Introduction

Giving the dictionary definition of words related to the research problem may appear appropriate because it is important to define specific terminology that readers may be unfamiliar with. However, anyone can look a word up in the dictionary and a general dictionary is not a particularly authoritative source because it doesn't take into account the context of your topic and doesn't offer particularly detailed information. Also, placed in the context of a particular discipline, a term or concept may have a different meaning than what is found in a general dictionary. If you feel that you must seek out an authoritative definition, use a subject specific dictionary or encyclopedia [e.g., if you are a sociology student, search for dictionaries of sociology]. A good database for obtaining definitive definitions of concepts or terms is Credo Reference .

Another Writing Tip

When Do I Begin?

A common question asked at the start of any paper is, "Where should I begin?" An equally important question to ask yourself is, "When do I begin?" Research problems in the social sciences rarely rest in isolation from history. Therefore, it is important to lay a foundation for understanding the historical context underpinning the research problem. However, this information should be brief and succinct and begin at a point in time that illustrates the study's overall importance. For example, a study that investigates coffee cultivation and export in West Africa as a key stimulus for local economic growth needs to describe the beginning of exporting coffee in the region and establishing why economic growth is important. You do not need to give a long historical explanation about coffee exports in Africa. If a research problem requires a substantial exploration of the historical context, do this in the literature review section. In your introduction, make note of this as part of the "roadmap" [see below] that you use to describe the organization of your paper.

Yet Another Writing Tip

Always End with a Roadmap

The final paragraph or sentences of your introduction should forecast your main arguments and conclusions and provide a brief description of the rest of the paper [the "roadmap"] that let's the reader know where you are going and what to expect. A roadmap is important because it helps the reader place the research problem within the context of their own perspectives about the topic. In addition, concluding your introduction with an explicit roadmap tells the reader that you have a clear understanding of the structural purpose of your paper. In this way, the roadmap acts as a type of promise to yourself and to your readers that you will follow a consistent and coherent approach to addressing the topic of inquiry. Refer to it often to help keep your writing focused and organized.

Table of Contents

Research Paper Introduction

Research paper introduction is the first section of a research paper that provides an overview of the study, its purpose, and the research question (s) or hypothesis (es) being investigated. It typically includes background information about the topic, a review of previous research in the field, and a statement of the research objectives. The introduction is intended to provide the reader with a clear understanding of the research problem, why it is important, and how the study will contribute to existing knowledge in the field. It also sets the tone for the rest of the paper and helps to establish the author’s credibility and expertise on the subject.

How to Write Research Paper Introduction

Writing an introduction for a research paper can be challenging because it sets the tone for the entire paper. Here are some steps to follow to help you write an effective research paper introduction:

• Start with a hook : Begin your introduction with an attention-grabbing statement, a question, or a surprising fact that will make the reader interested in reading further.
• Provide background information: After the hook, provide background information on the topic. This information should give the reader a general idea of what the topic is about and why it is important.
• State the research problem: Clearly state the research problem or question that the paper addresses. This should be done in a concise and straightforward manner.
• State the research objectives: After stating the research problem, clearly state the research objectives. This will give the reader an idea of what the paper aims to achieve.
• Provide a brief overview of the paper: At the end of the introduction, provide a brief overview of the paper. This should include a summary of the main points that will be discussed in the paper.
• Revise and refine: Finally, revise and refine your introduction to ensure that it is clear, concise, and engaging.

Structure of Research Paper Introduction

The following is a typical structure for a research paper introduction:

• Background Information: This section provides an overview of the topic of the research paper, including relevant background information and any previous research that has been done on the topic. It helps to give the reader a sense of the context for the study.
• Problem Statement: This section identifies the specific problem or issue that the research paper is addressing. It should be clear and concise, and it should articulate the gap in knowledge that the study aims to fill.
• Research Question/Hypothesis : This section states the research question or hypothesis that the study aims to answer. It should be specific and focused, and it should clearly connect to the problem statement.
• Significance of the Study: This section explains why the research is important and what the potential implications of the study are. It should highlight the contribution that the research makes to the field.
• Methodology: This section describes the research methods that were used to conduct the study. It should be detailed enough to allow the reader to understand how the study was conducted and to evaluate the validity of the results.
• Organization of the Paper : This section provides a brief overview of the structure of the research paper. It should give the reader a sense of what to expect in each section of the paper.

Research Paper Introduction Examples

Research Paper Introduction Examples could be:

Example 1: In recent years, the use of artificial intelligence (AI) has become increasingly prevalent in various industries, including healthcare. AI algorithms are being developed to assist with medical diagnoses, treatment recommendations, and patient monitoring. However, as the use of AI in healthcare grows, ethical concerns regarding privacy, bias, and accountability have emerged. This paper aims to explore the ethical implications of AI in healthcare and propose recommendations for addressing these concerns.

Example 2: Climate change is one of the most pressing issues facing our planet today. The increasing concentration of greenhouse gases in the atmosphere has resulted in rising temperatures, changing weather patterns, and other environmental impacts. In this paper, we will review the scientific evidence on climate change, discuss the potential consequences of inaction, and propose solutions for mitigating its effects.

Example 3: The rise of social media has transformed the way we communicate and interact with each other. While social media platforms offer many benefits, including increased connectivity and access to information, they also present numerous challenges. In this paper, we will examine the impact of social media on mental health, privacy, and democracy, and propose solutions for addressing these issues.

Example 4: The use of renewable energy sources has become increasingly important in the face of climate change and environmental degradation. While renewable energy technologies offer many benefits, including reduced greenhouse gas emissions and energy independence, they also present numerous challenges. In this paper, we will assess the current state of renewable energy technology, discuss the economic and political barriers to its adoption, and propose solutions for promoting the widespread use of renewable energy.

Purpose of Research Paper Introduction

The introduction section of a research paper serves several important purposes, including:

• Providing context: The introduction should give readers a general understanding of the topic, including its background, significance, and relevance to the field.
• Presenting the research question or problem: The introduction should clearly state the research question or problem that the paper aims to address. This helps readers understand the purpose of the study and what the author hopes to accomplish.
• Reviewing the literature: The introduction should summarize the current state of knowledge on the topic, highlighting the gaps and limitations in existing research. This shows readers why the study is important and necessary.
• Outlining the scope and objectives of the study: The introduction should describe the scope and objectives of the study, including what aspects of the topic will be covered, what data will be collected, and what methods will be used.
• Previewing the main findings and conclusions : The introduction should provide a brief overview of the main findings and conclusions that the study will present. This helps readers anticipate what they can expect to learn from the paper.

When to Write Research Paper Introduction

The introduction of a research paper is typically written after the research has been conducted and the data has been analyzed. This is because the introduction should provide an overview of the research problem, the purpose of the study, and the research questions or hypotheses that will be investigated.

Once you have a clear understanding of the research problem and the questions that you want to explore, you can begin to write the introduction. It’s important to keep in mind that the introduction should be written in a way that engages the reader and provides a clear rationale for the study. It should also provide context for the research by reviewing relevant literature and explaining how the study fits into the larger field of research.

Advantages of Research Paper Introduction

The introduction of a research paper has several advantages, including:

• Establishing the purpose of the research: The introduction provides an overview of the research problem, question, or hypothesis, and the objectives of the study. This helps to clarify the purpose of the research and provide a roadmap for the reader to follow.
• Providing background information: The introduction also provides background information on the topic, including a review of relevant literature and research. This helps the reader understand the context of the study and how it fits into the broader field of research.
• Demonstrating the significance of the research: The introduction also explains why the research is important and relevant. This helps the reader understand the value of the study and why it is worth reading.
• Setting expectations: The introduction sets the tone for the rest of the paper and prepares the reader for what is to come. This helps the reader understand what to expect and how to approach the paper.
• Grabbing the reader’s attention: A well-written introduction can grab the reader’s attention and make them interested in reading further. This is important because it can help to keep the reader engaged and motivated to read the rest of the paper.
• Creating a strong first impression: The introduction is the first part of the research paper that the reader will see, and it can create a strong first impression. A well-written introduction can make the reader more likely to take the research seriously and view it as credible.
• Establishing the author’s credibility: The introduction can also establish the author’s credibility as a researcher. By providing a clear and thorough overview of the research problem and relevant literature, the author can demonstrate their expertise and knowledge in the field.
• Providing a structure for the paper: The introduction can also provide a structure for the rest of the paper. By outlining the main sections and sub-sections of the paper, the introduction can help the reader navigate the paper and find the information they are looking for.

How to write an introduction for a research paper

Writing an introduction for a research paper can be one of the hardest parts of the writing process. How do you get started? In this post, we discuss the components of an introduction and explore strategies for writing one successfully.

What is an introduction?

The introduction to a research paper provides background information or context on the topic. It also includes the thesis statement and signposts that let the reader know what you will cover in the rest of the paper.

Depending on the type of research paper that you’re writing, you may also include a brief state of the field in your introduction. You might also put that in a separate section, called a literature review. Before you tackle writing your introduction, be sure to consult the assignment guidelines for your paper.

How to write an introduction

An introduction provides an overview of your topic and any background information that your readers need to know in order to understand the context. It generally concludes with an explicit statement of your position on the topic, which is known as your thesis statement.

The opening section

Many papers begin with a hook: a short anecdote or scenario that draws the reader in and gives a hint of what the paper will cover. A hook allows you to capture your reader’s attention and provides an anchor for the context that you will provide in the bulk of the introduction.

Most of your introduction should be taken up with background information, but this doesn’t mean that you should fill your opening section with overly general statements. Instead, provide key pieces of information (like statistics) that a reader would need to know in order to understand your main argument.

The thesis statement

Towards the end of the introduction, you should state your thesis, preferably in the form of "I argue that..." or "This paper argues that..." or a similar phrase. Although it’s called a “thesis statement,” your thesis can be more than one sentence.

Finally, an introduction contains a brief outline or "signposts" of what the rest of the article will cover (also known as forecasting statements). You can use language like, “in what follows,” or “in the rest of the paper,” to signal that you are describing what you’ll do in the remainder of the paper.

Tips for writing an introduction

1. don’t rely on generalizations.

An introduction is not simply filler. It has a very specific function in a research paper: to provide context that leads up to a thesis statement.

You may be tempted to start your paper with generalizations like, “many people believe that...” or, “in our society...,” or a general dictionary definition, because you’re not sure what kind of context to provide. Instead, use specific facts like statistics or historical anecdotes to open your paper.

2. State your thesis directly

Once you’ve provided the appropriate, and specific, background information on your topic, you can move on to stating your thesis. As a rule of thumb, state your thesis as directly as possible. Use phrases like “I argue that..” to indicate that you are laying out your main argument.

3. Include signposts

A strong introduction includes clear signposts that outline what you will cover in the rest of the paper. You can signal this by using words like, “in what follows,” and by describing the steps that you will take to build your argument.

4. Situate your argument within the scholarly conversation

Some types of research papers require a separate literature review in which you explore what others have written about your topic.

Even if you’re not required to have a formal literature review, you should still include at least a paragraph in which you engage with the scholarly debate on your chosen subject. Be sure to include direct quotes from your sources . You can use BibGuru’s citation generator to create accurate in-text citations for your quotes.

This section can come directly before your thesis statement or directly after it. In the former case, your state of the field will function as additional context for your thesis.

Frequently Asked Questions about how to write an introduction for a research paper

A good introduction provides specific background information on your topic, sets up your thesis statement, and includes signposts for what you’ll cover in the rest of the paper.

An introduction should include context, a thesis statement, and signposts.

Do not include generalizations, apologies for not being an expert, or dictionary definitions in your introduction.

The length of your introduction depends on the overall length of your paper. For instance, an introduction for an 8-10 page paper will likely be anywhere from 1-3 pages.

You can choose to start an introduction with a hook, an important statistic, an historical anecdote, or another specific piece of background information.

• If you are writing in a new discipline, you should always make sure to ask about conventions and expectations for introductions, just as you would for any other aspect of the essay. For example, while it may be acceptable to write a two-paragraph (or longer) introduction for your papers in some courses, instructors in other disciplines, such as those in some Government courses, may expect a shorter introduction that includes a preview of the argument that will follow.  
• In some disciplines (Government, Economics, and others), it’s common to offer an overview in the introduction of what points you will make in your essay. In other disciplines, you will not be expected to provide this overview in your introduction.  
• Avoid writing a very general opening sentence. While it may be true that “Since the dawn of time, people have been telling love stories,” it won’t help you explain what’s interesting about your topic.  
• Avoid writing a “funnel” introduction in which you begin with a very broad statement about a topic and move to a narrow statement about that topic. Broad generalizations about a topic will not add to your readers’ understanding of your specific essay topic.  
• Avoid beginning with a dictionary definition of a term or concept you will be writing about. If the concept is complicated or unfamiliar to your readers, you will need to define it in detail later in your essay. If it’s not complicated, you can assume your readers already know the definition.  
• Avoid offering too much detail in your introduction that a reader could better understand later in the paper.

How to Write a Research Introduction

The introduction to a research paper can be the most challenging part of the paper to write. The length of the introduction will vary depending on the type of research paper you are writing. An introduction should announce your topic, provide context and a rationale for your work, before stating your research questions and hypothesis. Well-written introductions set the tone for the paper, catch the reader's interest, and communicate the hypothesis or thesis statement.

Introducing the Topic of the Paper

• In scientific papers this is sometimes known as an "inverted triangle", where you start with the broadest material at the start, before zooming in on the specifics. [2] X Research source
• The sentence "Throughout the 20th century, our views of life on other planets have drastically changed" introduces a topic, but does so in broad terms.
• It provides the reader with an indication of the content of the essay and encourages them to read on.

• For example, if you were writing a paper about the behaviour of mice when exposed to a particular substance, you would include the word "mice", and the scientific name of the relevant compound in the first sentences.
• If you were writing a history paper about the impact of the First World War on gender relations in Britain, you should mention those key words in your first few lines.

• This is especially important if you are attempting to develop a new conceptualization that uses language and terminology your readers may be unfamiliar with.

• If you use an anecdote ensure that is short and highly relevant for your research. It has to function in the same way as an alternative opening, namely to announce the topic of your research paper to your reader.
• For example, if you were writing a sociology paper about re-offending rates among young offenders, you could include a brief story of one person whose story reflects and introduces your topic.
• This kind of approach is generally not appropriate for the introduction to a natural or physical sciences research paper where the writing conventions are different.

Establishing the Context for Your Paper

• It is important to be concise in the introduction, so provide an overview on recent developments in the primary research rather than a lengthy discussion.
• You can follow the "inverted triangle" principle to focus in from the broader themes to those to which you are making a direct contribution with your paper.
• A strong literature review presents important background information to your own research and indicates the importance of the field.

• By making clear reference to existing work you can demonstrate explicitly the specific contribution you are making to move the field forward.
• You can identify a gap in the existing scholarship and explain how you are addressing it and moving understanding forward.

• For example, if you are writing a scientific paper you could stress the merits of the experimental approach or models you have used.
• Stress what is novel in your research and the significance of your new approach, but don't give too much detail in the introduction.
• A stated rationale could be something like: "the study evaluates the previously unknown anti-inflammatory effects of a topical compound in order to evaluate its potential clinical uses".

Specifying Your Research Questions and Hypothesis

• The research question or questions generally come towards the end of the introduction, and should be concise and closely focused.
• The research question might recall some of the key words established in the first few sentences and the title of your paper.
• An example of a research question could be "what were the consequences of the North American Free Trade Agreement on the Mexican export economy?"
• This could be honed further to be specific by referring to a particular element of the Free Trade Agreement and the impact on a particular industry in Mexico, such as clothing manufacture.
• A good research question should shape a problem into a testable hypothesis.

• If possible try to avoid using the word "hypothesis" and rather make this implicit in your writing. This can make your writing appear less formulaic.
• In a scientific paper, giving a clear one-sentence overview of your results and their relation to your hypothesis makes the information clear and accessible. [10] X Trustworthy Source PubMed Central Journal archive from the U.S. National Institutes of Health Go to source
• An example of a hypothesis could be "mice deprived of food for the duration of the study were expected to become more lethargic than those fed normally".

• This is not always necessary and you should pay attention to the writing conventions in your discipline.
• In a natural sciences paper, for example, there is a fairly rigid structure which you will be following.
• A humanities or social science paper will most likely present more opportunities to deviate in how you structure your paper.

How to Write an Introduction for a Research Paper

How to write an introduction for a research paper? Eventually (and with practice) all writers will develop their own strategy for writing the perfect introduction for a research paper. Once you are comfortable with writing, you will probably find your own, but coming up with a good strategy can be tough for beginning writers.

The Purpose of an Introduction

Your opening paragraphs, phrases for introducing thesis statements, research paper introduction examples, using the introduction to map out your research paper.

• First write your thesis.Your thesis should state the main idea in specific terms.
• After you have a working thesis, tackle the body of your paper before you write the rest of the introduction. Each paragraph in the body should explore one specific topic that proves, or summarizes your thesis. Writing is a thinking process. Once you have worked your way through that process by writing the body of the paper, you will have an intimate understanding of how you are supporting your thesis. After you have written the body paragraphs, go back and rewrite your thesis to make it more specific and to connect it to the topics you addressed in the body paragraph.
• Revise your introduction several times, saving each revision. Be sure your introduction previews the topics you are presenting in your paper. One way of doing this is to use keywords from the topic sentences in each paragraph to introduce, or preview, the topics in your introduction.This “preview” will give your reader a context for understanding how you will make your case.
• Experiment by taking different approaches to your thesis with every revision you make. Play with the language in the introduction. Strike a new tone. Go back and compare versions. Then pick the one that works most effectively with the body of your research paper.
• Do not try to pack everything you want to say into your introduction. Just as your introduction should not be too short, it should also not be too long. Your introduction should be about the same length as any other paragraph in your research paper. Let the content—what you have to say—dictate the length.

The first page of your research paper should draw the reader into the text. It is the paper’s most important page and, alas, often the worst written. There are two culprits here and effective ways to cope with both of them.

First, the writer is usually straining too hard to say something terribly BIG and IMPORTANT about the thesis topic. The goal is worthy, but the aim is unrealistically high. The result is often a muddle of vague platitudes rather than a crisp, compelling introduction to the thesis. Want a familiar example? Listen to most graduation speakers. Their goal couldn’t be loftier: to say what education means and to tell an entire football stadium how to live the rest of their lives. The results are usually an avalanche of clichés and sodden prose.

The second culprit is bad timing. The opening and concluding paragraphs are usually written late in the game, after the rest of the thesis is finished and polished. There’s nothing wrong with writing these sections last. It’s usually the right approach since you need to know exactly what you are saying in the substantive middle sections of the thesis before you can introduce them effectively or draw together your findings. But having waited to write the opening and closing sections, you need to review and edit them several times to catch up. Otherwise, you’ll putting the most jagged prose in the most tender spots. Edit and polish your opening paragraphs with extra care. They should draw readers into the paper.

After you’ve done some extra polishing, I suggest a simple test for the introductory section. As an experiment, chop off the first few paragraphs. Let the paper begin on, say, paragraph 2 or even page 2. If you don’t lose much, or actually gain in clarity and pace, then you’ve got a problem.

There are two solutions. One is to start at this new spot, further into the text. After all, that’s where you finally gain traction on your subject. That works best in some cases, and we occasionally suggest it. The alternative, of course, is to write a new opening that doesn’t flop around, saying nothing.

What makes a good opening? Actually, they come in several flavors. One is an intriguing story about your topic. Another is a brief, compelling quote. When you run across them during your reading, set them aside for later use. Don’t be deterred from using them because they “don’t seem academic enough.” They’re fine as long as the rest of the paper doesn’t sound like you did your research in People magazine. The third, and most common, way to begin is by stating your main questions, followed by a brief comment about why they matter.

Whichever opening you choose, it should engage your readers and coax them to continue. Having done that, you should give them a general overview of the project—the main issues you will cover, the material you will use, and your thesis statement (that is, your basic approach to the topic). Finally, at the end of the introductory section, give your readers a brief road map, showing how the paper will unfold. How you do that depends on your topic but here are some general suggestions for phrase choice that may help:

• This analysis will provide …
• This paper analyzes the relationship between …
• This paper presents an analysis of …
• This paper will argue that …
• This topic supports the argument that…
• Research supports the opinion that …
• This paper supports the opinion that …
• An interpretation of the facts indicates …
• The results of this experiment show …
• The results of this research show …

Comparisons/Contrasts

• A comparison will show that …

Quotes, anecdotes, questions, examples, and broad statements—all of them can used successfully to write an introduction for a research paper. It’s instructive to see them in action, in the hands of skilled academic writers.

Let’s begin with David M. Kennedy’s superb history, Freedom from Fear: The American People in Depression and War, 1929–1945 . Kennedy begins each chapter with a quote, followed by his text. The quote above chapter 1 shows President Hoover speaking in 1928 about America’s golden future. The text below it begins with the stock market collapse of 1929. It is a riveting account of just how wrong Hoover was. The text about the Depression is stronger because it contrasts so starkly with the optimistic quotation.

“We in America today are nearer the final triumph over poverty than ever before in the history of any land.”—Herbert Hoover, August 11, 1928 Like an earthquake, the stock market crash of October 1929 cracked startlingly across the United States, the herald of a crisis that was to shake the American way of life to its foundations. The events of the ensuing decade opened a fissure across the landscape of American history no less gaping than that opened by the volley on Lexington Common in April 1775 or by the bombardment of Sumter on another April four score and six years later. The ratcheting ticker machines in the autumn of 1929 did not merely record avalanching stock prices. In time they came also to symbolize the end of an era. (David M. Kennedy, Freedom from Fear: The American People in Depression and War, 1929–1945 . New York: Oxford University Press, 1999, p. 10)

Kennedy has exciting, wrenching material to work with. John Mueller faces the exact opposite problem. In Retreat from Doomsday: The Obsolescence of Major War , he is trying to explain why Great Powers have suddenly stopped fighting each other. For centuries they made war on each other with devastating regularity, killing millions in the process. But now, Mueller thinks, they have not just paused; they have stopped permanently. He is literally trying to explain why “nothing is happening now.” That may be an exciting topic intellectually, it may have great practical significance, but “nothing happened” is not a very promising subject for an exciting opening paragraph. Mueller manages to make it exciting and, at the same time, shows why it matters so much. Here’s his opening, aptly entitled “History’s Greatest Nonevent”:

On May 15, 1984, the major countries of the developed world had managed to remain at peace with each other for the longest continuous stretch of time since the days of the Roman Empire. If a significant battle in a war had been fought on that day, the press would have bristled with it. As usual, however, a landmark crossing in the history of peace caused no stir: the most prominent story in the New York Times that day concerned the saga of a manicurist, a machinist, and a cleaning woman who had just won a big Lotto contest. This book seeks to develop an explanation for what is probably the greatest nonevent in human history. (John Mueller, Retreat from Doomsday: The Obsolescence of Major War . New York: Basic Books, 1989, p. 3)

In the space of a few sentences, Mueller sets up his puzzle and reveals its profound human significance. At the same time, he shows just how easy it is to miss this milestone in the buzz of daily events. Notice how concretely he does that. He doesn’t just say that the New York Times ignored this record setting peace. He offers telling details about what they covered instead: “a manicurist, a machinist, and a cleaning woman who had just won a big Lotto contest.” Likewise, David Kennedy immediately entangles us in concrete events: the stunning stock market crash of 1929. These are powerful openings that capture readers’ interests, establish puzzles, and launch narratives.

Sociologist James Coleman begins in a completely different way, by posing the basic questions he will study. His ambitious book, Foundations of Social Theory , develops a comprehensive theory of social life, so it is entirely appropriate for him to begin with some major questions. But he could just as easily have begun with a compelling story or anecdote. He includes many of them elsewhere in his book. His choice for the opening, though, is to state his major themes plainly and frame them as a paradox. Sociologists, he says, are interested in aggregate behavior—how people act in groups, organizations, or large numbers—yet they mostly examine individuals:

A central problem in social science is that of accounting for the function of some kind of social system. Yet in most social research, observations are not made on the system as a whole, but on some part of it. In fact, the natural unit of observation is the individual person…  This has led to a widening gap between theory and research… (James S. Coleman, Foundations of Social Theory . Cambridge, MA: Harvard University Press, 1990, pp. 1–2)

After expanding on this point, Coleman explains that he will not try to remedy the problem by looking solely at groups or aggregate-level data. That’s a false solution, he says, because aggregates don’t act; individuals do. So the real problem is to show the links between individual actions and aggregate outcomes, between the micro and the macro.

The major problem for explanations of system behavior based on actions and orientations at a level below that of the system [in this case, on individual-level actions] is that of moving from the lower level to the system level. This has been called the micro-to-macro problem, and it is pervasive throughout the social sciences. (Coleman, Foundations of Social Theory , p. 6)

Explaining how to deal with this “micro-to-macro problem” is the central issue of Coleman’s book, and he announces it at the beginning.

Coleman’s theory-driven opening stands at the opposite end of the spectrum from engaging stories or anecdotes, which are designed to lure the reader into the narrative and ease the path to a more analytic treatment later in the text. Take, for example, the opening sentences of Robert L. Herbert’s sweeping study Impressionism: Art, Leisure, and Parisian Society : “When Henry Tuckerman came to Paris in 1867, one of the thousands of Americans attracted there by the huge international exposition, he was bowled over by the extraordinary changes since his previous visit twenty years before.” (Robert L. Herbert, Impressionism: Art, Leisure, and Parisian Society . New Haven, CT: Yale University Press, 1988, p. 1.) Herbert fills in the evocative details to set the stage for his analysis of the emerging Impressionist art movement and its connection to Parisian society and leisure in this period.

David Bromwich writes about Wordsworth, a poet so familiar to students of English literature that it is hard to see him afresh, before his great achievements, when he was just a young outsider starting to write. To draw us into Wordsworth’s early work, Bromwich wants us to set aside our entrenched images of the famous mature poet and see him as he was in the 1790s, as a beginning writer on the margins of society. He accomplishes this ambitious task in the opening sentences of Disowned by Memory: Wordsworth’s Poetry of the 1790s :

Wordsworth turned to poetry after the revolution to remind himself that he was still a human being. It was a curious solution, to a difficulty many would not have felt. The whole interest of his predicament is that he did feel it. Yet Wordsworth is now so established an eminence—his name so firmly fixed with readers as a moralist of self-trust emanating from complete self-security—that it may seem perverse to imagine him as a criminal seeking expiation. Still, that is a picture we get from The Borderers and, at a longer distance, from “Tintern Abbey.” (David Bromwich, Disowned by Memory: Wordsworth’s Poetry of the 1790s . Chicago: University of Chicago Press, 1998, p. 1)

That’s a wonderful opening! Look at how much Bromwich accomplishes in just a few words. He not only prepares the way for analyzing Wordsworth’s early poetry; he juxtaposes the anguished young man who wrote it to the self-confident, distinguished figure he became—the eminent man we can’t help remembering as we read his early poetry.

Let us highlight a couple of other points in this passage because they illustrate some intelligent writing choices. First, look at the odd comma in this sentence: “It was a curious solution, to a difficulty many would not have felt.” Any standard grammar book would say that comma is wrong and should be omitted. Why did Bromwich insert it? Because he’s a fine writer, thinking of his sentence rhythm and the point he wants to make. The comma does exactly what it should. It makes us pause, breaking the sentence into two parts, each with an interesting point. One is that Wordsworth felt a difficulty others would not have; the other is that he solved it in a distinctive way. It would be easy for readers to glide over this double message, so Bromwich has inserted a speed bump to slow us down. Most of the time, you should follow grammatical rules, like those about commas, but you should bend them when it serves a good purpose. That’s what the writer does here.

The second small point is the phrase “after the revolution” in the first sentence: “Wordsworth turned to poetry after the revolution to remind himself that he was still a human being.” Why doesn’t Bromwich say “after the French Revolution”? Because he has judged his book’s audience. He is writing for specialists who already know which revolution is reverberating through English life in the 1790s. It is the French Revolution, not the earlier loss of the American colonies. If Bromwich were writing for a much broader audience—say, the New York Times Book Review—he would probably insert the extra word to avoid confusion.

The message “Know your audience” applies to all writers. Don’t talk down to them by assuming they can’t get dressed in the morning. Don’t strut around showing off your book learnin’ by tossing in arcane facts and esoteric language for its own sake. Neither will win over readers.

Bromwich, Herbert, and Coleman open their works in different ways, but their choices work well for their different texts. Your task is to decide what kind of opening will work best for yours. Don’t let that happen by default, by grabbing the first idea you happen upon. Consider a couple of different ways of opening your thesis and then choose the one you prefer. Give yourself some options, think them over, then make an informed choice.

Whether you begin with a story, puzzle, or broad statement, the next part of the introduction should pose your main questions and establish your argument. This is your thesis statement—your viewpoint along with the supporting reasons and evidence. It should be articulated plainly so readers understand full well what your paper is about and what it will argue.

After that, give your readers a road map of what’s to come. That’s normally done at the end of the introductory section (or, in a book, at the end of the introductory chapter). Here’s John J. Mearsheimer presenting such a road map in The Tragedy of Great Power Politics . He not only tells us the order of upcoming chapters, he explains why he’s chosen that order and which chapters are most important:

The Plan of the Book The rest of the chapters in this book are concerned mainly with answering the six big questions about power which I identified earlier. Chapter 2, which is probably the most important chapter in the book, lays out my theory of why states compete for power and why they pursue hegemony. In Chapters 3 and 4, I define power and explain how to measure it. I do this in order to lay the groundwork for testing my theory… (John J. Mearsheimer, The Tragedy of Great Power Politics . New York: W. W. Norton, 2001, p. 27)

As this excerpt makes clear, Mearsheimer has already laid out his “six big questions” in the introduction. Now he’s showing us the path ahead, the path to answering those questions.

At the end of the introduction, give your readers a road map of what’s to come. Tell them what the upcoming sections will be and why they are arranged in this particular order.

After having written your introduction it’s time to move to the biggest part: body of a research paper.

How to write an introduction section of a scientific article?

An article primarily includes the following sections: introduction, materials and methods, results, discussion, and conclusion. Before writing the introduction, the main steps, the heading and the familiarity level of the readers should be considered. Writing should begin when the experimental system and the equipment are available. The introduction section comprises the first portion of the manuscript, and it should be written using the simple present tense. Additionally, abbreviations and explanations are included in this section. The main goal of the introduction is to convey basic information to the readers without obligating them to investigate previous publications and to provide clues as to the results of the present study. To do this, the subject of the article should be thoroughly reviewed, and the aim of the study should be clearly stated immediately after discussing the basic references. In this review, we aim to convey the principles of writing the introduction section of a manuscript to residents and young investigators who have just begun to write a manuscript.

Introduction

When entering a gate of a magnificent city we can make a prediction about the splendor, pomposity, history, and civilization we will encounter in the city. Occasionally, gates do not give even a glimpse of the city, and it can mislead the visitors about inner sections of the city. Introduction sections of the articles are like gates of a city. It is a presentation aiming at introducing itself to the readers, and attracting their attention. Attractiveness, clarity, piquancy, and analytical capacity of the presentation will urge the reader to read the subsequent sections of the article. On the other hand as is understood from the motto of antique Greek poet Euripides “a bad beginning makes a bad ending”, ‘Introduction’ section of a scientific article is important in that it can reveal the conclusion of the article. [ 1 ]

It is useful to analyze the issues to be considered in the ‘Introduction’ section under 3 headings. Firstly, information should be provided about the general topic of the article in the light of the current literature which paves the way for the disclosure of the objective of the manuscript. Then the specific subject matter, and the issue to be focused on should be dealt with, the problem should be brought forth, and fundamental references related to the topic should be discussed. Finally, our recommendations for solution should be described, in other words our aim should be communicated. When these steps are followed in that order, the reader can track the problem, and its solution from his/her own perspective under the light of current literature. Otherwise, even a perfect study presented in a non-systematized, confused design will lose the chance of reading. Indeed inadequate information, inability to clarify the problem, and sometimes concealing the solution will keep the reader who has a desire to attain new information away from reading the manuscript. [ 1 – 3 ]

First of all, explanation of the topic in the light of the current literature should be made in clear, and precise terms as if the reader is completely ignorant of the subject. In this section, establishment of a warm rapport between the reader, and the manuscript is aimed. Since frantic plunging into the problem or the solution will push the reader into the dilemma of either screening the literature about the subject matter or refraining from reading the article. Updated, and robust information should be presented in the ‘Introduction’ section.

Then main topic of our manuscript, and the encountered problem should be analyzed in the light of the current literature following a short instance of brain exercise. At this point the problems should be reduced to one issue as far as possible. Of course, there might be more than one problem, however this new issue, and its solution should be the subject matter of another article. Problems should be expressed clearly. If targets are more numerous, and complex, solutions will be more than one, and confusing.

Finally, the last paragraphs of the ‘Introduction’ section should include the solution in which we will describe the information we generated, and related data. Our sentences which arouse curiosity in the readers should not be left unanswered. The reader who thinks to obtain the most effective information in no time while reading a scientific article should not be smothered with mysterious sentences, and word plays, and the readers should not be left alone to arrive at a conclusion by themselves. If we have contrary expectations, then we might write an article which won’t have any reader. A clearly expressed or recommended solutions to an explicitly revealed problem is also very important for the integrity of the ‘Introduction’ section. [ 1 – 5 ]

We can summarize our arguments with the following example ( Figure 1 ). The introduction section of the exemplary article is written in simple present tense which includes abbreviations, acronyms, and their explanations. Based on our statements above we can divide the introduction section into 3 parts. In the first paragraph, miniaturization, and evolvement of pediatric endourological instruments, and competitions among PNL, ESWL, and URS in the treatment of urinary system stone disease are described, in other words the background is prepared. In the second paragraph, a newly defined system which facilitates intrarenal access in PNL procedure has been described. Besides basic references related to the subject matter have been given, and their outcomes have been indicated. In other words, fundamental references concerning main subject have been discussed. In the last paragraph the aim of the researchers to investigate the outcomes, and safety of the application of this new method in the light of current information has been indicated.

An exemplary introduction section of an article

Apart from the abovementioned information about the introduction section of a scientific article we will summarize a few major issues in brief headings

Important points which one should take heed of:

• Abbreviations should be given following their explanations in the ‘Introduction’ section (their explanations in the summary does not count)
• Simple present tense should be used.
• References should be selected from updated publication with a higher impact factor, and prestigous source books.
• Avoid mysterious, and confounding expressions, construct clear sentences aiming at problematic issues, and their solutions.
• The sentences should be attractive, tempting, and comjprehensible.
• Firstly general, then subject-specific information should be given. Finally our aim should be clearly explained.

How Long Should a Research Paper Be?

How Long Should A Research Paper Be? An Overview

In short, research paper's average length can range from 1,500 words for research proposals and case studies - all the way to 100,000 words for large dissertations.

Research, by its nature of being complex, requires a careful and thorough elucidation of facts, notions, information, and the like - which is all reflected in its most optimal length.

Thus, one of the critical points that you need to focus on when writing either a complex research paper or a less complex research paper is your objective and how you can relay the latter in a particular context. Say you are writing a book review. Since you will only need to synthesize information from other sources to solidify your claim about a certain topic, you will perhaps use paraphrasing techniques, which offer a relatively lower word count when compared to a full-blown descriptive research paper.

Even when both types of research differ in word counts, they can effectively attain their objectives, given the different contexts in which they are written and constructed. 

Certainly, when asked about how long is a research paper, it surely depends on the objective or the type of research you will be using. Carrying out these objectives will warrant you to do certain paper writing tasks and techniques that are not necessarily long or short when you compare them to other research types. 

At Studyfy, we care for the attainment of your research objectives. We understand that achieving such will contribute to the success of your research completion. While maintaining the ideal word count for a research paper, you are in a meaningful position to understand the various elements that can enrich your paper, even if it looks overwhelming.

How Long Should the Introduction of a Research Paper Be?

The research introduction section most likely occupies approximately 30-40% of the entire research paper.

The introduction of a regular academic paper can total 1750-2000 words depending on the research type and complexity of the research niche or topic. That is why, in writing this section, you must enrich the content of your paper while maintaining readability and coherence for the benefit of your readers.

The introduction houses the background of the study. This is the part of the paper where the entire context of the paper is established. We all know that the research context is important as it helps the readers understand why the paper is even conducted in the first place. Thus, the impression of having a well-established context can only be found in the introduction. Now that we know the gravity of creating a good introduction, let us now ask how long this section should be.

Generally speaking, the paper’s introduction is the longest among all the sections. Aside from establishing the context, the introduction must house the historical underpinnings of the study (important for case studies and ethnographic research), salient information about all the variables in the study (including their relationship with other variables), and related literature and studies that can provide insight into the novelty and peculiarities of the current research project.

To better understand the general composition of your research introduction, you may refer to the breakdown of this section below:

• Context Establishment and Introduction of Key Terms. In this subsection, you will articulate the background (historical, social, economic, psychological, etc.) of the study, including the ecosystem and the niche of your study interest. Furthermore, key terms found as variables in your study must be properly defined operationally and theoretically, if necessary. This comprises 20% of the introduction, or about 350-500 words.
• Related Literature and Studies. This is the subsection where you will criticize and integrate existing literature and studies to highlight the research gap that you intend to fill in. This comprises 25% of the introduction or about 450-600 words.
• Thesis statement. This part of the introduction can only be a paragraph or a couple of sentences, as this needs to be straightforward in relaying the identified research gap of the researchers. This comprises 5% of the introduction or about 90-100 words.
• Objectives or Research Questions. This subsection should outline the aims of the study, especially highlighting the inquiries that concern the relationship between the variables and how the research will progress to fill in the identified gaps. This comprises 5% of the introduction or about 90-100 words.

Theoretical and/or Conceptual Framework. These frameworks, when better assisted with a visual representation, guide the entire research process and provide a structure for understanding the relationship between the variables in the study. This comprises 10% of the introduction or about 180-200 words.

Elements of Good Research Writing Process– While Maintaining the Ideal Word Count!

• Clarity of Purpose . All types of writing, whether long or short, have its clarity of purpose as the heart of the text. In research, it is manifested through the inclusion of a research question or hypothesis. A good research paper does not repeat these elements without a purpose in mind. Though they can be emphasized throughout the development of the paper, the manner of doing it must be in a logical and purposeful way. 

To guide you in writing process of doing so, you can ask yourself the following questions:

• Is the research question or hypothesis clearly stated?
• Does the introduction provide a clear overview of the purpose of the study?
• Does the purpose of the study repeat purposefully in the latter sections of the paper?
• Does the purpose of the study repeat logically in the latter sections of the paper?

2. Literature Review . When appending related literature and studies to your paper, the question must not revolve around whether you have supplied a lot of these pieces of information, making your article wordy and ideal. While the literature review adds a significant ‘chunk’ to your paper, with some paper formats even allotting a specific section for it, we must carefully consider what and how we can integrate them. It subsequently entails a critical analysis of a piece of literature or study and logically places it beside information that you desire to contest. As they say, a good literature review identifies knowledge gaps, highlights the author’s familiarity with the topic, and provides an overview of the research areas that show a disparity of agreement. In order to have these characteristics, you can ask yourself the following questions:

• Have I integrated relevant literature in my review?
• Have I placed it logically within a specific piece of information based on my presumption?
• Do they identify a concept or piece of information that is otherwise unknown to the field?
• Have I critically analyzed existing research to identify the research gap?

3. Logical Flow. Research will not be whole without its parts. Researchers must know how to tie everything together and ensure that each part is functional in itself and supplements with other parts. When dealing with a large body of text, the logical flow of the paper might be a considerable concern. Along with the confusion brought about by the wordiness and complexity of the topic, your readers might get lost because of incoherence and inconsistencies with the presentation of ideas, leading to them not reading your paper any further. Thus, while ensuring that you get the word count that you want, you might want to ask yourself these questions first:

• Does the introduction progress logically from the general background to the specific research question?
• Do the transition devices between sections and individual paragraphs of the body facilitate a smooth flow of ideas?
• Is there a clear hierarchy of ideas, with each paragraph contributing to the overall argument?
• Have I organized ideas in a way that makes the document easy to track?
• Have I pursued a logical sequence of presenting information?

4. Language Use and Style. Developing an academic language throughout your paper and maintaining a formal style of paper writing are all the more important in research writing process, and mind you, it can also help you increase your word count in a sustainable way! Incorporating this form of language and style into your paper entails more than just adding incoherent or overly manufactured words that may be viewed as fillers.

Strategies and known practices are said to hit multiple objectives without compromising the quality of the paper. You may expand your points by providing detailed explanations, introducing sufficient pieces of evidence that supports your claims, addressing counterargument through the presentation of related literature or studies, or clarifying complex concepts through chunking. To better understand these techniques, some of these questions might be helpful for you:

• Is the language clear and concise?
• Have I avoided unnecessary jargon or complex sentences or paragraphs?
• Have I avoided repetition or redundancy in the document?
• Have I expanded on key points by providing more detailed explanations and examples?
• Have I discussed nuances, variations, or exceptions to your results?
• Have I clarified some complex concepts or theories by chunking them into more detailed explanations?

How Long Should a Paragraph Be in a Research Paper?

For the research paper introduction section, a typical paragraph count will be 12-15, excluding the literature review section. Each subsection has 1-2 individual paragraphs. The mentioned section, on the other hand, can have paragraphs totaling 10-20. The conclusion section, on the other hand, is considered ideal if it has 5-7 paragraphs. 

The paragraph count differs from one research type to another and even from one paper section to another. While it is worth deciding how long should a paragraph be in a research paper, it is more important to take note of the importance of ideas that should be included in each paragraph within a certain section. Take the review of the literature section as an example. The number of literature in the paper is said to be equal to the number of paragraphs allotted for the section. The reason lies in the uniformity of importance these pieces of literature hold, provided that they are closely associated with the research gap. 

Do you feel like you need to pay for a research paper in hopes of finding a model article with the right paragraph count? Look no further, as Studyfy has its in-house research paper writing service that houses professionals and experts for your academic paper writing help. Its reasonable price– no deadline markup nor additional hidden charges– is tantamount to the expertise each writer has put into their work.

How Long Should a Conclusion Be in a Research Paper?

A concluding section, then, must only comprise 5% of the total word count of the paper, translating to approximately 400 words. This measly allocation may put you into a flimsy situation, especially if you do not know how to manage your vocabulary well and you keep on adding filler words that can sacrifice the importance of this section. Ditch the nonsense and construct your conclusion in a concise yet enriching way.

In concluding a research paper, it is important to always synthesize the big chunks of information examined in the data analysis and discussion. As worn out as the reader may look after reaching this point, the conclusion must act as a “mellow point” for them, entrusting them only with important pointers of the study. Sometimes, the conclusion part of the paper, even though less wordy than its preceding sections, may be difficult to construct, as you still need to have a basis– a scaffold– to refer to, and synthesizing, just like analyzing and evaluating data, is just as hard and laborious.

Through its superb essay writing services , plus applying top-notch quality assurance to academic papers like research articles, Studyfy can help you achieve the best for last with an effective, meaningful, and content-rich conclusion. Your readers will not think twice about using your study as a model for their own works!

How Long is a Research Paper in terms of its Various Types?

As mentioned in the first part of the article, the word count of an academic paper is dependent on the type of research you wish to conduct. While the general word count has been given, we cannot deny the fact that this threshold is only an estimation. There might be a time when you are tasked to create a research article that is different from a standard IMRAD-structured (Introduction, Methodology, Results, Analysis, Discussion) research paper. You are in for a treat, as we will provide you with a cheat sheet for the word count of several types of write-ups in the realm of research:

Research Proposal

Specific Purpose/s: A preliminary outline that contains the research question, minimal literature review, methodology, and significance of the research undertaking.

"Word Count Range: 1500-3000 words"

Review Article

Specific Purpose/s: Review bodies of literature about an overarching topic or niche, analyze a particular section, synthesize according to certain themes, and identify knowledge gaps from the findings.

"Word Count Range: 5000-10,000 words"

Meta-Analysis

Specific Purpose/s: Involves the use of statistical analyses of multiple studies to provide a quantitative synthesis of the evidence.

"Word Count Range: 5000-15,000 words"

Specific Purpose/s: Presents an in-depth and intrusive analysis of a specific case, one which aims to illustrate a broader concept or novel phenomenon.

"Word Count Range: 1500-5000 words"

Conference Paper

Specific Purpose/s: Presents a brief introduction, salient research findings, and implications connected to a given theme by a conference or colloquium.

"Word Count Range: 2000-5000 words"

Dissertation

Specific Purpose/s: Regarded as a terminal scholarly requirement for doctorate students, this is an in-depth discussion of an otherwise original research finding, often written in chapters. It contributes significantly to the body of knowledge of a particular study of interest.

"Word Count Range: 50,000-100,000 words (depending on the institution)"

Are you contemplating buying research papers of different types? Studyfy got your back! Its roster of writers and editing experts leaves no space for errors, ensuring that both quality and quantity– that’s right: content and word count are not compromised. The variety of expertise within ensures that all research and scholarly works are delivered to your liking. Pay less– no hidden charges and markups while you enjoy the best quality of writing with Studyfy.

Frequently Asked Questions

How long is the introduction in a research paper.

AThe introduction takes up about 30-40% of the entire paper since the context and research background should be specified and further discussed. For a general academic paper with 4000 words, the introduction must be approximately 1500 words. You can do the math for the rest!

How long is a research paper, considering that there are many of them?

There is no one-size-fits-all guideline in determining the word count of a plethora of research papers in the world. Although there is an accepted word count range for each research type (as presented in the previous section), there are several factors that should likewise be considered in determining the word count: specific guidelines set by the institution you are working with, the complexity of the topic, audience, and depth of analysis. 

Do I have to include all of the prescribed subsections of the introduction to increase the word count?

While the prescribed subsections have significant functions in the research paper introduction, some of them are not required to be included. The decisions depend on the type of research you wish to conduct and the external guidelines that you might need to follow. Some disciplines, such as social sciences, require a research article to have a theoretical framework, whereas others do not. Some research papers follow the standard IMRAD paper format that infuses the literature review section into the introduction, while the Germanic Thesis paper format, for example, regards the former as a separate section.

How do I increase my word count without compromising the quality of my research paper?

The dilemma of choosing quality over quantity has long been debunked: you do not have to choose in the first place. All you need is a set of writing strategies and techniques that will target those two birds using one stone. You may provide more detail to some ambiguous or novel terms. You can add additional works of literature to some concepts that promote abstraction. You may include examples or empirical pieces of evidence to create a more concrete representation of a concept or theory. Lastly, you may use subheadings to efficiently allocate word count for your chosen discussion topics.

Why is it important to track the word count of a research paper?

There are various reasons why we need to do it. Some institutions that publish scholarly journals follow certain guidelines in word count as one of the primary requirements. A specified limit enables researchers to allocate the number of words to several sections of their writing efficiently. Most institutions also use paper length as a predictor of publication cost. The longer the word count is, the costlier the publication will be. Lastly, reading engagement is affected by word count, as readers tend to shy away from reading an article that is long, boring, and insubstantial. 

Can a writing service help me achieve my goals of writing within the right word count range?

Certainly! Studyfy offers several academic services, including writing services and research papers for sale . Understanding your various writing needs, writers can cater to the needed style, word count, formatting, and any other aspects so that you can have the best quality write-up without having to fear extra charges and big markups.

How Long Should a Research Paper Be? Data from 61,519 Examples

I analyzed a random sample of 61,519 full-text research papers, uploaded to PubMed Central between the years 2016 and 2021, in order to answer the questions:

What is the typical overall length of a research paper? and how long should each section be?

I used the BioC API to download the data (see the References section below).

Here’s a summary of the key findings

1- The median length of a research paper is 4,133 words (equivalent to 166 sentences or 34 paragraphs), excluding the abstract and references, with 90% of papers being between 2,023 and 8,284 words.

2- A typical article is divided in the following way:

• Introduction section: 14.6% of the total word count.
• Methods section: 29.7% of the total word count.
• Results section: 26.2% of the total word count.
• Discussion section: 29.4% of the total word count.

Notice that the Materials and methods is the longest section of a professionally written article. So always write this section in enough depth to provide the readers with the necessary details that allow them to replicate your study if they wanted to without requiring further information.

Overall length of a research paper

Let’s start by looking at the maximum word count allowed in some of the well-known journals. Note that the numbers reported in this table include the Abstract , Figure legends and References unless otherwise specified:

[1] excluding figure legends [2] excluding references

⚠ Note A review paper is either a systematic review or a meta-analysis, and an original research paper refers to either an observational or an experimental study conducted by the authors themselves.

Notice the large variability between these journals: The maximum number of words allowed ranges between 3,000 and 9,000 words.

Next, let’s look at our data.

Here’s a table that describes the length of a research paper in our sample:

90% of research papers have a word count between 2,023 and 8,284. So it will be a little weird to see a word count outside of this range.

Our data also agree that a typical review paper is a little bit longer than a typical original research paper but not by much (3,858 vs 3,708 words).

Length of each section in a research article

The median article with an IMRaD structure (i.e. contains the following sections: Introduction , Methods , Results and Discussion ) is in general characterized by a short 553 words introduction. And the methods, results and discussion sections are about twice the size of the introduction:

8 Key Elements of a Research Paper Structure + Free Template (2024)

Table of contents

Brinda Gulati

Welcome to the twilight zone of research writing. You’ve got your thesis statement and research evidence, and before you write the first draft, you need a wireframe — a structure on which your research paper can stand tall. 

When you’re looking to share your research with the wider scientific community, your discoveries and breakthroughs are important, yes. But what’s more important is that you’re able to communicate your research in an accessible format. For this, you need to publish your paper in journals. And to have your research published in a journal, you need to know how to structure a research paper.

Here, you’ll find a template of a research paper structure, a section-by-section breakdown of the eight structural elements, and actionable insights from three published researchers.

Let’s begin!

Why is the Structure of a Research Paper Important?

A research paper built on a solid structure is the literary equivalent of calcium supplements for weak bones.

Richard Smith of BMJ says, “...no amount of clever language can compensate for a weak structure."

There’s space for your voice and creativity in your research, but without a structure, your paper is as good as a beached whale — stranded and bloated.

A well-structured research paper:

• Communicates your credibility as a student scholar in the wider academic community.
• Facilitates accessibility for readers who may not be in your field but are interested in your research.
• Promotes clear communication between disciplines, thereby eliminating “concept transfer” as a rate-limiting step in scientific cross-pollination.
• Increases your chances of getting published!

Research Paper Structure Template

Why Was My Research Paper Rejected?

A desk rejection hurts — sometimes more than stubbing your pinky toe against a table.

Oftentimes, journals will reject your research paper before sending it off for peer review if the architecture of your manuscript is shoddy. 

The JAMA Internal Medicine , for example, rejected 78% of the manuscripts it received in 2017 without review. Among the top 10 reasons? Poor presentation and poor English . (We’ve got fixes for both here, don’t you worry.)

5 Common Mistakes in a Research Paper Structure

• Choppy transitions : Missing or abrupt transitions between sections disrupt the flow of your paper. Read our guide on transition words here. 
• Long headings : Long headings can take away from your main points. Be concise and informative, using parallel structure throughout.
• Disjointed thoughts : Make sure your paragraphs flow logically from one another and support your central point.
• Misformatting : An inconsistent or incorrect layout can make your paper look unprofessional and hard to read. For font, spacing, margins, and section headings, strictly follow your target journal's guidelines.
• Disordered floating elements : Ill-placed and unlabeled tables, figures, and appendices can disrupt your paper's structure. Label, caption, and reference all floating elements in the main text.

What Is the Structure of a Research Paper? 

The structure of a research paper closely resembles the shape of a diamond flowing from the general ➞ specific ➞ general. 

We’ll follow the IMRaD ( I ntroduction , M ethods , R esults , and D iscussion) format within the overarching “context-content-conclusion” approach:

➞ The context sets the stage for the paper where you tell your readers, “This is what we already know, and here’s why my research matters.”

➞ The content is the meat of the paper where you present your methods, results, and discussion. This is the IMRad (Introduction, Methods, Results, and Discussion) format — the most popular way to organize the body of a research paper. 

➞ The conclusion is where you bring it home — “Here’s what we’ve learned, and here’s where it plays out in the grand scheme of things.”

Now, let’s see what this means section by section.

1. Research Paper Title

A research paper title is read first, and read the most. 

The title serves two purposes: informing readers and attracting attention . Therefore, your research paper title should be clear, descriptive, and concise . If you can, avoid technical jargon and abbreviations. Your goal is to get as many readers as possible.

In fact, research articles with shorter titles describing the results are cited more often . 

An impactful title is usually 10 words long, plus or minus three words. 

For example:

• "Mortality in Puerto Rico after Hurricane Maria" (word count = 7)
• “A Review of Practical Techniques For the Diagnosis of Malaria” (word count = 10)

2. Research Paper Abstract

In an abstract, you have to answer the two whats :

• What has been done?
• What are the main findings?

The abstract is the elevator pitch for your research. Is your paper worth reading? Convince the reader here. 

✏️ NOTE : According to different journals’ guidelines, sometimes the title page and abstract section are on the same page. 

An abstract ranges from 200-300 words and doubles down on the relevance and significance of your research. Succinctly.  

This is your chance to make a second first impression. 

If you’re stuck with a blob of text and can’t seem to cut it down, a smart AI elf like Wordtune can help you write a concise abstract! The AI research assistant also offers suggestions for improved clarity and grammar so your elevator pitch doesn’t fall by the wayside.

3. Introduction Section

What does it do.

Asks the central research question.

Pre-Writing Questions For the Introduction Section

The introduction section of your research paper explains the scope, context, and importance of your project. 

I talked to Swagatama Mukherjee , a published researcher and graduate student in Neuro-Oncology studying Glioblastoma Progression. For the Introduction, she says, focus on answering three key questions:

• What isn’t known in the field? 
• How is that knowledge gap holding us back?
• How does your research focus on answering this problem?

When Should You Write It?

Write it last. As you go along filling in the body of your research paper, you may find that the writing is evolving in a different direction than when you first started. 

Organizing the Introduction

Visualize the introduction as an upside-down triangle when considering the overall outline of this section. You'll need to give a broad introduction to the topic, provide background information, and then narrow it down to specific research. Finally, you'll need a focused research question, hypothesis, or thesis statement. The move is from general ➞ specific.

✨️ BONUS TIP: Use the famous CARS model by John Swales to nail this upside-down triangle. 

4. methods section.

Describes what was done to answer the research question, and how.

Write it first . Just list everything you’ve done, and go from there. How did you assign participants into groups? What kind of questionnaires have you used? How did you analyze your data? 

Write as if the reader were following an instruction manual on how to duplicate your research methodology to the letter. 

Organizing the Methods Section

Here, you’re telling the story of your research. 

Write in as much detail as possible, and in the chronological order of the experiments. Follow the order of the results, so your readers can track the gradual development of your research. Use headings and subheadings to visually format the section.

This skeleton isn’t set in stone. The exact headings will be determined by your field of study and the journal you’re submitting to. 

✨️ BONUS TIP : Drowning in research? Ask Wordtune to summarize your PDFs for you!

5. results section .

Reports the findings of your study in connection to your research question.

Write the section only after you've written a draft of your Methods section, and before the Discussion.

This section is the star of your research paper. But don't get carried away just yet. Focus on factual, unbiased information only. Tell the reader how you're going to change the world in the next section. The Results section is strictly a no-opinions zone.

How To Organize Your Results 

A tried-and-true structure for presenting your findings is to outline your results based on the research questions outlined in the figures.

Whenever you address a research question, include the data that directly relates to that question.

What does this mean? Let’s look at an example:

Here's a sample research question:

How does the use of social media affect the academic performance of college students?

Make a statement based on the data:

College students who spent more than 3 hours per day on social media had significantly lower GPAs compared to those who spent less than 1 hour per day (M=2.8 vs. M=3.4; see Fig. 2).

You can elaborate on this finding with secondary information:

The negative impact of social media use on academic performance was more pronounced among freshmen and sophomores compared to juniors and seniors ((F>25), (S>20), (J>15), and (Sr>10); see Fig. 4).

Finally, caption your figures in the same way — use the data and your research question to construct contextual phrases. The phrases should give your readers a framework for understanding the data: 

Figure 4. Percentage of college students reporting a negative impact of social media on academic performance, by year in school.

Dos and Don’ts For The Results Section

6. discussion section.

Explains the importance and implications of your findings, both in your specific area of research, as well as in a broader context. 

Pre-Writing Questions For the Discussion Section

• What is the relationship between these results and the original question in the Introduction section?
• How do your results compare with those of previous research? Are they supportive, extending, or contradictory to existing knowledge?
• What is the potential impact of your findings on theory, practice, or policy in your field?
• Are there any strengths or weaknesses in your study design, methods, or analysis? Can these factors affect how you interpret your results?
• Based on your findings, what are the next steps or directions for research? Have you got any new questions or hypotheses?

Before the Introduction section, and after the Results section. 

Based on the pre-writing questions, five main elements can help you structure your Discussion section paragraph by paragraph:

• Summary : Restate your research question/problem and summarize your major findings.
• Interpretations : Identify patterns, contextualize your findings, explain unexpected results, and discuss if and how your results satisfied your hypotheses.
• Implications: Explore if your findings challenge or support existing research, share new insights, and discuss the consequences in theory or practice.
• Limitations : Acknowledge what your results couldn’t achieve because of research design or methodological choices.
• Recommendations : Give concrete ideas about how further research can be conducted to explore new avenues in your field of study. 

Dos and Don’ts For the Discussion Section

Aritra Chatterjee , a licensed clinical psychologist and published mental health researcher, advises, “If your findings are not what you expected, disclose this honestly. That’s what good research is about.”

7. Acknowledgments

Expresses gratitude to mentors, colleagues, and funding sources who’ve helped your research.

Write this section after all the parts of IMRaD are done to reflect on your research journey without getting distracted midway. 

After a lot of scientific writing, you might get stumped trying to write a few lines to say thanks. Don’t let this be the reason for a late or no-submission.

Wordtune can make a rough draft for you. 

All you then have to do is edit the AI-generated content to suit your voice, and replace any text placeholders as needed:

8. References

Lists all the works/sources used in your research with proper citations. 

The two most important aspects of referencing are: 

• Following the correct format; and 
• Properly citing the sources. 

Keep a working document of the works you’ve referenced as you go along, but leave the finishing touches for last after you’ve completed the body of your research paper — the IMRaD.

Tips For Writing the References Section

The error rate of references in several scientific disciplines is 25%-54% . 

Don’t want to be a part of this statistic? We got you.

• Choose quality over quantity : While it's tempting to pad your bibliography to seem more scholarly, this is a rookie mistake.   Samantha Summers , a museum professional based in Canada, is a published researcher in Medieval History and Critical Philanthropy studies. According to her, “Adding in a citation just to lengthen your bibliography and without engaging deeply with the cited work doesn’t make for good writing.” We ought to listen to her advice — she has three Master’s degrees to her name for a reason. 
• Select the correct referencing guide : Always cross-check with your chosen journal’s or institution’s preference for either Harvard, MLA, APA, Chicago, or IEEE. 
• Include recent studies and research : Aim to cite academically ripe sources — not overripe. Research from the past half-decade or so is ideal, whereas studies from the 80s or 90s run a higher risk of being stale. 
• Use a reliable reference manager software : Swagatama recommends several free resources that have helped her get her research organized and published — Zotero and Mendeley are top contenders, followed by EndNote . 

By the end, your References section will look something like this:

How to Write the First Draft of a Research Paper with Paperpal? 

Do you encounter writer’s block during the first draft of a research paper? Crafting a clear outline from your initial ideas and notes can feel like a daunting first hurdle. Many researchers and students struggle with the initial stages of research paper writing. Uncertainties about content structure, information selection, and weaving complex findings into a cohesive narrative can lead to staring at a blank page.

• AI-generated outlines with a personalized approach 
• Identify gaps to strengthen your research paper 
• Step 1: Creating a research paper outline  
• Step 2: Breaking down the outline into sections  
• Step 3: Drafting the research paper  

A glimpse into academic forums and social media gives a clear picture that many researchers across the world go through similar problems while writing the first draft of a research paper. Where to begin? What should I write? How to begin? How to compile 2-3+ years of research into a 2500 or 5000-word research paper? If you’re grappling with these concerns, do not worry. You’re not alone.   

Researchers face a mountain of work when it comes to writing papers. Paperpal decided to tackle this challenge and, in the process, discovered some fascinating writing habits: 

• Start verbally: Some researchers find their flow by talking through their ideas first. They record themselves or brainstorm with a friend, then use these spoken notes as a springboard for their draft. 
• Write on the go: Others prioritize keeping their thoughts flowing freely. They write in bursts, leaving the structuring and editing for later. 
• Divide and Conquer: For some, especially new researchers, a structured approach works best. They break the paper into sections, focusing on building each one in detail before assembling the final draft. 
• Outlines: Many researchers swear by outlines. Outlines provide a roadmap, complete with headings, subheadings, and key points. This saves time in the long run by eliminating the need for major restructuring later. You can focus on polishing the language and adding academic vocabulary during the final edit . 

Inspired by the outline method, Paperpal set out to create a tool that would give researchers a head start. This led to the development of Paperpal’s AI-generated outlines, which build a rough skeleton for your draft, allowing you to flesh out each section with confidence.

It needs to clarify:

• What exactly you’re planning to study,
• Why the subject is research-worthy,
• What you will do to achieve the set research goals.

In other words, a concept paper is a brief summary of the larger project . It helps students identify gaps and weaknesses in their research rationale and develop a consistent justification for the planned study.

In terms of its purpose, a concept paper is similar to a research proposal , as it describes a research focus and enables early feedback from the supervising committee. Based on these insights, the student can refine the planned study’s structure and gain more confidence in their research.

Concept Paper vs. Research Proposal

As we’ve just noted, there are many similarities between a research proposal and a concept paper. To make sure you don't confuse them, take a look at their main distinctions:

Concept Paper

Research Proposal

What Questions Should Be Addressed in a Concept Paper?

A concept paper should answer the following essential questions:

• What problem are you addressing?
• Which stakeholders may find this issue significant?
• How will you achieve the research objectives?
• What research methods will you use?
• What are the benefits of your research project?
• What metric will you use to evaluate your study success?
• Who will participate in the research process?

✍️ How to Write a Concept Paper?

A concept paper is an excellent way of presenting your ideas persuasively and professionally. There is no rigid template or outline regarding this paper’s structure. However, certain conventions still exist.

Experts recommend including the following elements in your paper to increase your chances of successful application:

• Decide on the purpose . The “why” question should come first when writing a concept paper, as it will lay the basis for your research rationale. You should identify your objectives and determine the audiences for whom they are relevant.
• Select a sound topic . While a purpose is a broad rationale for the project, a topic gives it a narrow focus and makes the research doable. Your topic may specify a location, population, or particular research approach that makes the project original.
• Come up with a title . Now that you have a topic, shape it into an attention-grabbing and exciting title. Make it intriguing to motivate the reviewers to read the whole text. We recommend using our handy title generator to streamline this task.
• Research and gather data . Next comes the detailed research on the chosen topic. Check what other scholars have found on the subject and how they approached the study. Using this evidence, you will be able to identify reliable sources.
• State the issue . The initial research will expose the gaps and problems requiring attention. These gaps may be reformulated as an issue you will address in the forthcoming research project.
• Define your goals . With a clear research topic and purpose in mind, you can formulate a list of concrete goals to address in the study. You may use the SMART tactic to develop actionable goals.
• Provide research questions . Based on the purpose and objectives, develop a list of research questions and hypotheses. A research question is a query you pose at the beginning of the study. You then answer it with the help of data collected during research.
• Write a literature review . The next step is a preliminary literature review . This part should contain key works of scholars in your field, core topics they discuss, and the findings they cover.
• State the methodology . Another vital part of any concept paper is the research design you’re proposing. Make a detailed plan that will include the research type (qualitative or quantitative), your theoretical framework, data collection tools , approaches, the populations of your interest, etc.
• Create a timeline . The timing of your research also matters when it comes to financing. That’s why you should give a realistic schedule of all important research steps to show how much time you will need to attain all objectives.
• Include references . Giving credit to other scholars’ intellectual work is at the heart of professional academic conduct. Make sure to indicate all external sources on which you relied when composing the paper. Our citation maker can help with popular styles like APA, MLA, or Chicago.

How Long Is a Concept Paper?

There is no one-size-fits-all rule for determining your concept paper’s length. Typically, reviewers expect to see anywhere from one to five pages of text (most often 2-3 pages) in these assignments. Yet, some funding applications require longer and more detailed concept justifications – up to 20 pages.

What Are Good Research Question Examples?

When developing a concept paper, you should find an area that matches your professional interests and is within your competency. Here are some examples of research questions that will stimulate critical thinking:

• How is acid rain connected to local diesel vehicle use?
• How can the process of 5G network integration be accelerated in Texas?
• What are the legal constraints of surrogate mother service promotion in Alabama?

💡 Concept Paper Tips

Following our professional tips and recommendations, you can quickly improve your concept paper writing skills. Here are a couple of tricks to help you achieve the best results:

• Be direct . The choice of language and structuring of your material can make a real difference. It is important to sound confident and straightforward to get your message to potential funders or partners.
• Add credible statistics . If possible, use statistics and numbers to support your project’s relevance. Also, consider mentioning how you will monitor progress toward planned objectives.
• Don’t write too much . Staying within the word count is essential. Nobody would read a concept paper that’s 10+ pages long if the initial request were to write three papers at most.
• Maintain a professional tone . A professional tone inspires confidence and forms an opinion of you as a serious researcher. It also demonstrates your respect for the subject matter.
• Provide visual aids . Illustrations can help you clarify complex ideas, improve understanding, and make your proposal more memorable for the reader.
• Don’t skip the revision stage . Editing and proofreading your content is an opportunity to strengthen its impact and improve the audience’s impression. Funders are unlikely to consider your idea if it’s presented in poorly written text with punctuation and grammatical errors .

We do hope that our free concept paper maker will help you complete your academic assignment quickly and efficiently. If you liked the article, don’t forget to share it with friends. We also recommend using our handy research question generator for your future tasks!

High-confidence placement of low-occupancy fragments into electron density using the anomalous signal of sulfur and halogen atoms

a School of Pharmacy, University College London, 29-39 Brunswick Square, London WC1N 1AX, United Kingdom, b Pharmacognosy and Pharmaceutical Chemistry Department, College of Pharmacy, Taibah University, Al-Madinah Al-Mounawarah 30078, Saudi Arabia, c European Molecular Biology Laboratory, 38000 Grenoble, France, and d Diamond Light Source, Harwell Science and Innovation Campus, Chilton, Didcot OX11 0DE, United Kingdom * Correspondence e-mail: [email protected] , [email protected] , [email protected]

Fragment-based drug design using X-ray crystallography is a powerful technique to enable the development of new lead compounds, or probe molecules, against biological targets. This study addresses the need to determine fragment binding orientations for low-occupancy fragments with incomplete electron density, an essential step before further development of the molecule. Halogen atoms play multiple roles in drug discovery due to their unique combination of electronegativity, steric effects and hydrophobic properties. Fragments incorporating halogen atoms serve as promising starting points in hit-to-lead development as they often establish halogen bonds with target proteins, potentially enhancing binding affinity and selectivity, as well as counteracting drug resistance. Here, the aim was to unambiguously identify the binding orientations of fragment hits for SARS-CoV-2 nonstructural protein 1 (nsp1) which contain a combination of sulfur and/or chlorine, bromine and iodine substituents. The binding orientations of carefully selected nsp1 analogue hits were focused on by employing their anomalous scattering combined with Pan-Dataset Density Analysis ( PanDDA ). Anomalous difference Fourier maps derived from the diffraction data collected at both standard and long-wavelength X-rays were compared. The discrepancies observed in the maps of iodine-containing fragments collected at different energies were attributed to site-specific radiation-damage stemming from the strong X-ray absorption of I atoms, which is likely to cause cleavage of the C—I bond. A reliable and effective data-collection strategy to unambiguously determine the binding orientations of low-occupancy fragments containing sulfur and/or halogen atoms while mitigating radiation damage is presented.

Keywords: SARS-CoV-2 nsp1 ; fragment-based drug discovery ; fragment orientations ; anomalous scattering ; PanDDA ; halogens ; COVID-19 ; low occupancy ; radiation damage .

PDB references: nsp1–1E7, 8rf2 ; nsp1–7G3, 8rf3 ; nsp1–9D4, 8rf4 ; nsp1–11A7, 8rf5 ; nsp1–11A7_AL5, 8rf6 ; nsp1–11A7_AL6, 8rf8 ; nsp1–7H2_AL1, 8rfc ; nsp1–7H2_AL2, 8rfd ; nsp1–6A6, 8rff

In this study, we describe our approach to the high- confidence placement of fragments binding to SARS-CoV-2 nsp1 that contain S and/or halogen atoms (Cl, Br and I) into electron density using anomalous diffraction. We chose SARS-CoV-2 nsp1 as a model system because its crystals routinely diffract to high resolution, fragments can easily be soaked in without compromising crystal quality and several hundred data sets are at our disposal. For our investigation, we selected fragments that had already displayed low occupancy and incomplete electron density. The effectiveness of anomalous difference Fourier maps and PanDDA in the placement of these low-occupancy fragments into incomplete electron density was investigated. Furthermore, a study was conducted to determine how site-specific radiation damage develops with X-ray absorption during the collection of diffraction data, exemplified by an iodine-containing fragment. Finally, we demonstrate that the integration of anomalous difference Fourier maps and PanDDA offers a reliable and effective strategy for fitting fragments into challenging electron density with a high degree of confidence.

2.1. Expression, purification and crystallization of SARS-CoV-2 nsp1 10–126

Fragment hits 6A6, 1E7, 7G3, 9D4 and 11A7 were obtained from the Maybridge Ro3 library (Thermo Fisher Scientific, United Kingdom), while fragment hits 7H2_AL1, 7H2_AL2, 11A7_AL5 and 11A7_AL6 were purchased from Molport (Beacon, New York, USA), with a purity nominally exceeding 95%. The compounds were dissolved in DMSO-d 6 (Sigma, St Louis, Missouri, USA; CAS No. 2206-27-1) at a concentration of 200 m M . Each stock (2 µl) was mixed with 8 µl crystallization condition, resulting in a fragment concentration of 40 m M in the crystallization condition, which also contained 20% DMSO-d 6 . Fragments or DMSO-d 6 solutions (1.5 µl) were added to the approximately 1 µl volume of the crystallization drop, resulting in a final fragment concentration of 24 m M containing approximately 12% DMSO-d 6 . These drops were incubated at room temperature for 4–5 h. No additional cryoprotection was necessary as 25%( w / v ) polyethylene glycol 3350 was present in the crystallization condition. The crystals were harvested using loops, cryocooled in liquid nitrogen and stored in pucks for sample shipment.

FBDD has emerged as a powerful strategy for developing novel lead compounds and advancing drug development. However, FBDD also presents challenges that differentiate it from traditional small-molecule drug-discovery approaches. A fundamental aspect is the markedly weak binding affinity of fragments for their targets, which is typically in the low-millimolar range. Additionally, the fragments are small, simple and typically incorporate at least one aromatic ring, therefore having fewer rotatable bonds, which renders them planar and quasi-symmetric. These intrinsic features introduce additional complexities in determining their binding orientations.

Radiation-damage effects in data collection for fragments containing bromine and iodine have rarely been considered. Anomalous data have also rarely been applied to simultaneously determine the binding modes of fragments containing S and halogen atoms. This study of data-collection strategies for fragments containing S and/or halogenated atoms or substituents suggest that a carefully designed strategy for data collection is necessary depending on the purpose of the study. For the identification of fragment hits containing iodine, a low dose during data collection is recommended to avoid site-specific radiation damage, in particular when the X-ray energy is close to the iodine absorption edge. For the determination of binding orientations of fragments containing both S/Cl and halogen atoms, the incident X-ray energy should be above and close to the sulfur/chlorine absorption edge to ensure that the anomalous signals of both can be observed for unambiguous manual fragment placement.

In conclusion, this study has shown how the challenge of determining the binding orientation(s) for low-occupancy and difficult-to-fit fragments can successfully be addressed for sulfur- and/or halogen-containing fragments. This method is poised to significantly improve the efficacy and success rate of FBDD during rational drug design.

Accurate landslide displacement prediction is an important component to realize landslide warning. For the displacement prediction of landslides, how to improve the prediction accuracy has been the focus on such research problems. Therefore, in this paper, the TS-SSA-LSTM landslide displacement prediction model is proposed as an example for landslides in Anxi County, Quanzhou City, Fujian Province. First, the cumulative displacement is decomposed into trend and period terms by time series. Then, the MIC coefficients are utilized for correlation test to screen the input terms of the prediction model. Then, the prediction models of trend and period terms are established by LSTM model, and SSA algorithm is introduced in this process for optimization. Finally, after obtaining the prediction results of the trend and period terms, the displacement data are reconstructed according to the basic theory of time series to obtain the final displacement prediction results. By comparing the RMSE, MAE and R \(^2\) of the TS-SSA-LSTM landslide displacement model with those of the traditional RNN and LSTM landslide displacement models, it is shown that the established landslide displacement prediction models have higher accuracy and stability. From the prediction results of TS-SSA-LSTM, the deviation from it and the real monitoring value is small and the fitting degree is high, which indicates that the TS-SSA-LSTM types proposed to this paper can effectively predict the displacement change of the landslide in the study case.
