How to Write the Rationale for a Research Paper

• Research Process
• Peer Review

A research rationale answers the big SO WHAT? that every adviser, peer reviewer, and editor has in mind when they critique your work. A compelling research rationale increases the chances of your paper being published or your grant proposal being funded. In this article, we look at the purpose of a research rationale, its components and key characteristics, and how to create an effective research rationale.

Updated on September 19, 2022

The rationale for your research is the reason why you decided to conduct the study in the first place. The motivation for asking the question. The knowledge gap. This is often the most significant part of your publication. It justifies the study's purpose, novelty, and significance for science or society. It's a critical part of standard research articles as well as funding proposals.

Essentially, the research rationale answers the big SO WHAT? that every (good) adviser, peer reviewer, and editor has in mind when they critique your work.

A compelling research rationale increases the chances of your paper being published or your grant proposal being funded. In this article, we look at:

• the purpose of a research rationale
• its components and key characteristics
• how to create an effective research rationale

What is a research rationale?

Think of a research rationale as a set of reasons that explain why a study is necessary and important based on its background. It's also known as the justification of the study, rationale, or thesis statement.

Essentially, you want to convince your reader that you're not reciting what other people have already said and that your opinion hasn't appeared out of thin air. You've done the background reading and identified a knowledge gap that this rationale now explains.

A research rationale is usually written toward the end of the introduction. You'll see this section clearly in high-impact-factor international journals like Nature and Science. At the end of the introduction there's always a phrase that begins with something like, "here we show..." or "in this paper we show..." This text is part of a logical sequence of information, typically (but not necessarily) provided in this order:

Here's an example from a study by Cataldo et al. (2021) on the impact of social media on teenagers' lives.

Note how the research background, gap, rationale, and objectives logically blend into each other.

The authors chose to put the research aims before the rationale. This is not a problem though. They still achieve a logical sequence. This helps the reader follow their thinking and convinces them about their research's foundation.

Elements of a research rationale

We saw that the research rationale follows logically from the research background and literature review/observation and leads into your study's aims and objectives.

This might sound somewhat abstract. A helpful way to formulate a research rationale is to answer the question, “Why is this study necessary and important?”

Generally, that something has never been done before should not be your only motivation. Use it only If you can give the reader valid evidence why we should learn more about this specific phenomenon.

A well-written introduction covers three key elements:

• What's the background to the research?
• What has been done before (information relevant to this particular study, but NOT a literature review)?
• Research rationale

Now, let's see how you might answer the question.

1. This study complements scientific knowledge and understanding

Discuss the shortcomings of previous studies and explain how'll correct them. Your short review can identify:

• Methodological limitations . The methodology (research design, research approach or sampling) employed in previous works is somewhat flawed.

Example : Here , the authors claim that previous studies have failed to explore the role of apathy “as a predictor of functional decline in healthy older adults” (Burhan et al., 2021). At the same time, we know a lot about other age-related neuropsychiatric disorders, like depression.

Their study is necessary, then, “to increase our understanding of the cognitive, clinical, and neural correlates of apathy and deconstruct its underlying mechanisms.” (Burhan et al., 2021).

• Contextual limitations . External factors have changed and this has minimized or removed the relevance of previous research.

Example : You want to do an empirical study to evaluate the effects of the COVID-19 pandemic on the number of tourists visiting Sicily. Previous studies might have measured tourism determinants in Sicily, but they preceded COVID-19.

• Conceptual limitations . Previous studies are too bound to a specific ideology or a theoretical framework.

Example : The work of English novelist E. M. Forster has been extensively researched for its social, political, and aesthetic dimensions. After the 1990s, younger scholars wanted to read his novels as an example of gay fiction. They justified the need to do so based on previous studies' reliance on homophobic ideology.

This kind of rationale is most common in basic/theoretical research.

2. This study can help solve a specific problem

Here, you base your rationale on a process that has a problem or is not satisfactory.

For example, patients complain about low-quality hospital care on weekends (staff shortages, inadequate attention, etc.). No one has looked into this (there is a lack of data). So, you explore if the reported problems are true and what can be done to address them. This is a knowledge gap.

Or you set out to explore a specific practice. You might want to study the pros and cons of several entry strategies into the Japanese food market.

It's vital to explain the problem in detail and stress the practical benefits of its solution. In the first example, the practical implications are recommendations to improve healthcare provision.

In the second example, the impact of your research is to inform the decision-making of businesses wanting to enter the Japanese food market.

This kind of rationale is more common in applied/practical research.

3. You're the best person to conduct this study

It's a bonus if you can show that you're uniquely positioned to deliver this study, especially if you're writing a funding proposal .

For an anthropologist wanting to explore gender norms in Ethiopia, this could be that they speak Amharic (Ethiopia's official language) and have already lived in the country for a few years (ethnographic experience).

Or if you want to conduct an interdisciplinary research project, consider partnering up with collaborators whose expertise complements your own. Scientists from different fields might bring different skills and a fresh perspective or have access to the latest tech and equipment. Teaming up with reputable collaborators justifies the need for a study by increasing its credibility and likely impact.

When is the research rationale written?

You can write your research rationale before, or after, conducting the study.

In the first case, when you might have a new research idea, and you're applying for funding to implement it.

Or you're preparing a call for papers for a journal special issue or a conference. Here , for instance, the authors seek to collect studies on the impact of apathy on age-related neuropsychiatric disorders.

In the second case, you have completed the study and are writing a research paper for publication. Looking back, you explain why you did the study in question and how it worked out.

Although the research rationale is part of the introduction, it's best to write it at the end. Stand back from your study and look at it in the big picture. At this point, it's easier to convince your reader why your study was both necessary and important.

How long should a research rationale be?

The length of the research rationale is not fixed. Ideally, this will be determined by the guidelines (of your journal, sponsor etc.).

The prestigious journal Nature , for instance, calls for articles to be no more than 6 or 8 pages, depending on the content. The introduction should be around 200 words, and, as mentioned, two to three sentences serve as a brief account of the background and rationale of the study, and come at the end of the introduction.

If you're not provided guidelines, consider these factors:

• Research document : In a thesis or book-length study, the research rationale will be longer than in a journal article. For example, the background and rationale of this book exploring the collective memory of World War I cover more than ten pages.
• Research question : Research into a new sub-field may call for a longer or more detailed justification than a study that plugs a gap in literature.

Which verb tenses to use in the research rationale?

It's best to use the present tense. Though in a research proposal, the research rationale is likely written in the future tense, as you're describing the intended or expected outcomes of the research project (the gaps it will fill, the problems it will solve).

How to Write the Rationale of the Study in Research (Examples)

What is the Rationale of the Study?

The rationale of the study is the justification for taking on a given study. It explains the reason the study was conducted or should be conducted. This means the study rationale should explain to the reader or examiner why the study is/was necessary. It is also sometimes called the “purpose” or “justification” of a study. While this is not difficult to grasp in itself, you might wonder how the rationale of the study is different from your research question or from the statement of the problem of your study, and how it fits into the rest of your thesis or research paper. 

The rationale of the study links the background of the study to your specific research question and justifies the need for the latter on the basis of the former. In brief, you first provide and discuss existing data on the topic, and then you tell the reader, based on the background evidence you just presented, where you identified gaps or issues and why you think it is important to address those. The problem statement, lastly, is the formulation of the specific research question you choose to investigate, following logically from your rationale, and the approach you are planning to use to do that.

Table of Contents:

How to write a rationale for a research paper , how do you justify the need for a research study.

• Study Rationale Example: Where Does It Go In Your Paper?

The basis for writing a research rationale is preliminary data or a clear description of an observation. If you are doing basic/theoretical research, then a literature review will help you identify gaps in current knowledge. In applied/practical research, you base your rationale on an existing issue with a certain process (e.g., vaccine proof registration) or practice (e.g., patient treatment) that is well documented and needs to be addressed. By presenting the reader with earlier evidence or observations, you can (and have to) convince them that you are not just repeating what other people have already done or said and that your ideas are not coming out of thin air. 

Once you have explained where you are coming from, you should justify the need for doing additional research–this is essentially the rationale of your study. Finally, when you have convinced the reader of the purpose of your work, you can end your introduction section with the statement of the problem of your research that contains clear aims and objectives and also briefly describes (and justifies) your methodological approach. 

When is the Rationale for Research Written?

The author can present the study rationale both before and after the research is conducted. 

• Before conducting research : The study rationale is a central component of the research proposal . It represents the plan of your work, constructed before the study is actually executed.
• Once research has been conducted : After the study is completed, the rationale is presented in a research article or  PhD dissertation  to explain why you focused on this specific research question. When writing the study rationale for this purpose, the author should link the rationale of the research to the aims and outcomes of the study.

What to Include in the Study Rationale

Although every study rationale is different and discusses different specific elements of a study’s method or approach, there are some elements that should be included to write a good rationale. Make sure to touch on the following:

• A summary of conclusions from your review of the relevant literature
• What is currently unknown (gaps in knowledge)
• Inconclusive or contested results  from previous studies on the same or similar topic
• The necessity to improve or build on previous research, such as to improve methodology or utilize newer techniques and/or technologies

There are different types of limitations that you can use to justify the need for your study. In applied/practical research, the justification for investigating something is always that an existing process/practice has a problem or is not satisfactory. Let’s say, for example, that people in a certain country/city/community commonly complain about hospital care on weekends (not enough staff, not enough attention, no decisions being made), but you looked into it and realized that nobody ever investigated whether these perceived problems are actually based on objective shortages/non-availabilities of care or whether the lower numbers of patients who are treated during weekends are commensurate with the provided services.

In this case, “lack of data” is your justification for digging deeper into the problem. Or, if it is obvious that there is a shortage of staff and provided services on weekends, you could decide to investigate which of the usual procedures are skipped during weekends as a result and what the negative consequences are. 

In basic/theoretical research, lack of knowledge is of course a common and accepted justification for additional research—but make sure that it is not your only motivation. “Nobody has ever done this” is only a convincing reason for a study if you explain to the reader why you think we should know more about this specific phenomenon. If there is earlier research but you think it has limitations, then those can usually be classified into “methodological”, “contextual”, and “conceptual” limitations. To identify such limitations, you can ask specific questions and let those questions guide you when you explain to the reader why your study was necessary:

Methodological limitations

• Did earlier studies try but failed to measure/identify a specific phenomenon?
• Was earlier research based on incorrect conceptualizations of variables?
• Were earlier studies based on questionable operationalizations of key concepts?
• Did earlier studies use questionable or inappropriate research designs?

Contextual limitations

• Have recent changes in the studied problem made previous studies irrelevant?
• Are you studying a new/particular context that previous findings do not apply to?

Conceptual limitations

• Do previous findings only make sense within a specific framework or ideology?

Study Rationale Examples

Let’s look at an example from one of our earlier articles on the statement of the problem to clarify how your rationale fits into your introduction section. This is a very short introduction for a practical research study on the challenges of online learning. Your introduction might be much longer (especially the context/background section), and this example does not contain any sources (which you will have to provide for all claims you make and all earlier studies you cite)—but please pay attention to how the background presentation , rationale, and problem statement blend into each other in a logical way so that the reader can follow and has no reason to question your motivation or the foundation of your research.

Background presentation

Since the beginning of the Covid pandemic, most educational institutions around the world have transitioned to a fully online study model, at least during peak times of infections and social distancing measures. This transition has not been easy and even two years into the pandemic, problems with online teaching and studying persist (reference needed) . 

While the increasing gap between those with access to technology and equipment and those without access has been determined to be one of the main challenges (reference needed) , others claim that online learning offers more opportunities for many students by breaking down barriers of location and distance (reference needed) .  

Rationale of the study

Since teachers and students cannot wait for circumstances to go back to normal, the measures that schools and universities have implemented during the last two years, their advantages and disadvantages, and the impact of those measures on students’ progress, satisfaction, and well-being need to be understood so that improvements can be made and demographics that have been left behind can receive the support they need as soon as possible.

Statement of the problem

To identify what changes in the learning environment were considered the most challenging and how those changes relate to a variety of student outcome measures, we conducted surveys and interviews among teachers and students at ten institutions of higher education in four different major cities, two in the US (New York and Chicago), one in South Korea (Seoul), and one in the UK (London). Responses were analyzed with a focus on different student demographics and how they might have been affected differently by the current situation.

How long is a study rationale?

In a research article bound for journal publication, your rationale should not be longer than a few sentences (no longer than one brief paragraph). A  dissertation or thesis  usually allows for a longer description; depending on the length and nature of your document, this could be up to a couple of paragraphs in length. A completely novel or unconventional approach might warrant a longer and more detailed justification than an approach that slightly deviates from well-established methods and approaches.

How do you Write the Rationale for Research?

• By DiscoverPhDs
• October 21, 2020

What is the Rationale of Research?

The term rationale of research means the reason for performing the research study in question. In writing your rational you should able to convey why there was a need for your study to be carried out. It’s an important part of your research paper that should explain how your research was novel and explain why it was significant; this helps the reader understand why your research question needed to be addressed in your research paper, term paper or other research report.

The rationale for research is also sometimes referred to as the justification for the study. When writing your rational, first begin by introducing and explaining what other researchers have published on within your research field.

Having explained the work of previous literature and prior research, include discussion about where the gaps in knowledge are in your field. Use these to define potential research questions that need answering and explain the importance of addressing these unanswered questions.

The rationale conveys to the reader of your publication exactly why your research topic was needed and why it was significant . Having defined your research rationale, you would then go on to define your hypothesis and your research objectives.

Final Comments

Defining the rationale research, is a key part of the research process and academic writing in any research project. You use this in your research paper to firstly explain the research problem within your dissertation topic. This gives you the research justification you need to define your research question and what the expected outcomes may be.

Rationale for Research: Writing Tips & Examples

The rationale for research justifies the need for a study and its potential contributions. It highlights gaps in existing knowledge and aims to fill those gaps. A well-crafted rationale increases the chances of publication success and funding approval. The rationale typically follows a logical sequence from literature review to research objectives. Its length varies based on the type of research document, ranging from a few sentences to several pages .

📘 Guidelines for Writing the Rationale for Research

📏 length.

• Scope : The length of the rationale can vary depending on the overall length of the research proposal or paper .
• Detail : Typically, the rationale should be concise and focused, ranging from a few sentences to a page or two(typically 4-10 sentences ).
• Purpose : Aim to provide enough detail to justify the importance and relevance of the study without being overly lengthy or repetitive.

📍 Position

• Placement : The rationale is usually positioned early in the research proposal or paper, often following the introduction or background section.
• Sequence : It should come after the research question or hypothesis has been clearly stated, as the rationale aims to justify why the research question is important and worth investigating.
• Integration : In some cases, the rationale may be integrated into the introduction or background section, rather than being a separate section.

🔗 Transition Words

• Function : Transition words help to connect ideas and create a logical flow in the rationale.
• Contrast/Gaps : “However,” “Despite,” “While,” “Although”
• Logical Connection : “Therefore,” “Thus,” “Consequently,” “As a result”
• Addition of Points : “Moreover,” “Furthermore,” “In addition”
• Purposeful Action : “To address this gap,” “To fill this need,” “To bridge this gap”

📝 Example of a Well-Drafted Rationale

• “Despite the growing prevalence of obesity among children, current interventions have shown limited long-term effectiveness. [Transition: However,] recent studies suggest that family-based interventions targeting both diet and physical activity may be more promising. [Transition: Therefore,] the proposed study aims to investigate the effectiveness of a novel family-based intervention program for treating childhood obesity, which combines nutrition education, physical activity promotion, and parent-child bonding activities. [Transition: Moreover,] the study will assess the long-term maintenance of weight loss and lifestyle changes, which has been a major challenge in previous interventions. [Transition: To address this gap,] the findings of this study could inform the development of more effective and sustainable interventions for childhood obesity, ultimately improving the health and well-being of children and their families.”

In this example, the rationale is concise (one paragraph), positioned after the background information on childhood obesity, and uses transition words ( however, therefore, moreover, to address this gap ) to create a logical flow and connection between ideas.

Rationale for Research Practices: Good vs. Bad

Rationale for Research-Good Research Practices Across Disciplines

Let’s go deeper into writing a good research rationale. You’ll learn the structure, important parts, and ways to make a strong point. This guide helps both seasoned researchers and beginners. You’ll learn to make your research matter and interest your readers with its significance .

What is a Rationale for Research?

knowledge gap the study wants to fill and its possible contribution to literature .

Overview of the Research Rationale

A solid research rationale starts with careful literature review analysis. This step identifies areas where the knowledge base is incomplete. It makes sure the new research does something novel. 1 The rationale sums up key points from previous studies. It talks about what we’re still not sure about or which results are mixed. It shows how the new study will add to what’s already known.

Significance and Novelty of Research

The research rationale underlines the study’s significance and novelty . It should explain the practical and theoretical benefits the study offers. 2 Take, for example, Cataldo et al.’s (2021) research on social media and teens. This study might discuss its real-world impacts and its input to theories about teen and tech use. 2

Rationales can also show a study’s practical benefits .Like, Burhan et al. (2021) could explain how their study on apathy aids with new elderly care interventions .

When is the Rationale for Research Written?

The rationale for research is key at different times in research. It’s crucial early on or after a study ends. At each point, it has a specific role.

Before the Research: Research Proposal

Before starting a research project, the rationale for research is vital. It’s a big part of the research proposal . Here, the rationale lays out the study’s plan, goals, and significance .

After the Research: Research Paper or Dissertation

After the study is over, the rationale for research goes in the final research paper or dissertation . It explains why the research focused on certain aims and how the results fit the bigger picture.

It doesn’t matter if it’s early or late, the rationale for research is crucial. It shows why the study matters, making readers see its worth for the field.

Basis for Writing the Research Rationale

Creating a strong research rationale starts with a detailed literature review . This means deeply looking into past studies. It helps you spot where there’s not enough information in the current knowledge about your topic.By carefully checking what’s already known, a literature review ensures your study will add something new. It won’t just repeat what others have done before. 1

Literature Review

A thorough literature review is key to solid research reasoning. It lets you pull together the main points from studies that have gone before. This way, you really understand what is known about your study area. 1 This stop you from covering old ground but also shows what needs more looking into. This sets up your research to bring a fresh perspective. 3

Identifying Gaps in Knowledge

Finding where there is still knowledge to be found is one big goal of the literature review . These gaps might be due to different or unclear findings, study restrictions, or lack of research for certain groups. 1 By recognizing these knowledge gaps , your study becomes important. It tries to answer key questions and push the field forward. 3

Avoiding Duplication

Another goal is to make sure you’re not just repeating what’s already known. The literature review is crucial in this. It shows you what’s been done already and lets you check your approach to be unique. 1 This step helps avoid doing work that’s already been covered. It opens the door for new ideas, building on existing knowledge.

Length of the Research Rationale

The length of the research rationale in a research proposal or article is typically a few sentences 1 . But for a thesis or dissertation , it could be a couple of paragraphs.

How long the research rationale length is can change. It depends on the field or how new and unusual the idea is 1 . A very new idea might need more explaining than something continuing existing research 2 .

The prestigious journal Nature specifies that articles should ideally be no more than 6 to 8 pages long, with the introduction being around 200 words including a brief account of the background and rationale of the study.

In some cases like a thesis or a lengthy book study, the research rationale can be quite long. It might even be more than ten pages, depending on the details.

The length of the research rationale is often set by the journal or sponsor’s rules 2 .

Basic Elements of the Research Rationale

A well-crafted research rationale sets the stage for a successful study. It justifies the investigation with solid reasons. This reason should show the importance and originality of the work you want to do.

Literature Review Conclusions

It’s critical to summarize what’s already known in your field. This summary helps put your study in context. It also helps you see what needs to be researched further, known as research gaps and knowledge gaps .

Knowledge Gaps

Looking at past studies should show where we need more information. These areas without enough data give a good reason to continue researching. By finding and talking about these knowledge gaps , you can make sure your study brings something new.

Controversial or Inconclusive Findings

Sometimes, past research doesn’t give clear answers. It might even have different or uncertain results. In these cases, your study could help by clarifying or solving these issues.

Building on Previous Research

Your research should aim to add to what we already know. It can be about any new questions, updating old ideas, or using new technology for more insights. This approach shows the value in your work.

By combining these essential elements, your research’s foundation becomes strong. It makes a clear case for the study’s unique contribution and importance .

Example of a Research Rationale

Abc xyz is a new microalgae species found in fish tanks. It’s getting attention for lots of carotenoids and a special carotenoid profile . Although Abc xyz algae have worried fish farmers, some studies show they could help aquaculture .

In this genus, only a few microalgal species have been studied for carotenoid content . So far, they haven’t found great sources of these healthy compounds. 4 Studying Abc xyz’s carotenoid profile will help us find new and useful carotenoids. They could be a great natural source for aquaculture . 4

Every research rationale should mention previous findings, gaps in knowledge, and new research questions. This is to update what we know and make it better.

A research rationale can be over ten pages in a thesis . It depends on the topic’s depth. 2 Dissertations might have even longer explanations, maybe a few paragraphs.

• Preliminary data from a literature review helps make the study’s reasons clear. It also stops us from repeating things we already know.
• Research that brings together different fields can be very powerful. It makes the work more trustworthy and important.
• Working with well-known partners makes our studies more reliable. It also helps show why our research is needed.

Importance of Describing the Research Rationale

Explaining why you are doing research is key. It shows the big picture and new ideas of your project. When you tell people why you’re studying something, it makes them see how important and needed your work is. It’s important to share your research’s purpose clearly.

Why you are researching something is really important, especially in a research proposal . But, keep it short, a few sentences are enough. However, for a thesis or dissertation , you might get to talk more about it. You could use a couple of paragraphs to explain in more detail.

To build a strong research rationale , start with a deep look at the literature. Studying what’s already out there helps you find where new studies are needed. This way, your research can truly add something new and not just repeat what others have done.

A solid research rationale should talk about key findings from the literature, points not yet looked into, and areas where old studies don’t agree. It should also explain why more research in this area is needed.

Showing the need for your research makes it more important and valuable. By clearly explaining why your work is needed, you increase its chance of getting recognized by researchers.

Writing a Clear and Concise Rationale

To explain your research’s purpose and what it means, crafting a clear and short rationale is key. The problem-solution-rationale model is a good way to do this. First, point out the problem or issue. Then, suggest a solution. Finally, show why that solution is the right one.

Problem-Solution-Rationale Model

The model makes your ideas clear and logical. Start by clearly stating the problem or gap in knowledge. Then, talk about your solution. This could be a new approach or method. At the end, explain why your choice is the best to solve the problem.

Language for Signaling Rationale

Using certain phrases can show your rationale clearly. Phrases like “in order to,” “for the following reasons,” and “the reason this was done” work well. They make your argument stronger and easier to follow.

A good rationale for research is brief but persuasive. It highlights why your work matters. Using the problem-solution-rationale model and clear language can make your rationale effective. This is important for starting off your research on the right foot. 3

Justifying the Rationale

Showing a strong rationale justification is vital for your research to make an impact. It proves why your study matters and what it can offer the world. By explaining your study’s purpose clearly, you can highlight its big role in advancing what we know.

Showing Importance and Significance

To make your research’s rationale stand out, talk about its importance using phrases like “This was important because…” This shows how your study led to important results or met specific needs, making your work more valuable.

Say something like, “This was significant because it explored a topic not studied enough, which is key for moving our understanding forward. Or, “The importance was in challenging common beliefs, giving a new view on the issue we looked into.”

Writing a rationale

How to write a rationale.

What is a rationale?

A rationale is when you are asked to give the reasoning or justification for an action or a choice you make.

There is a focus on the ‘ why ’ in a rationale: why you chose to do something, study or focus on something. It is a set of statements of purpose and significance and often addresses a gap or a need.

A rationale in Australian academic writing is rarely a whole task by itself.  It is often a part of a bigger task. For example, a part of a lesson plan might be to provide a rationale for why you chose to teach particular content or use a certain resource or activity, or you may be asked to provide a rationale as to why you chose a particular theory to apply or a concept to support.

You may be called upon to provide a rationale:

prior to an action or decision; why you plan to do something and how, or

• after you have acted or decided something; reflecting, looking back, why you did something and how it worked or not.

You can use language to signal you are clearly providing a rationale in your writing. You can link your rationale to learning outcomes or aims for a lesson, activity or assessment task.

A model: problem-solution-rationale

A rationale can be provided by offering longer essay-based support for why it is important to do something in a certain way – in that sense, a whole paper can be a rationale.

However, a more specific or focused way of thinking about a rationale is how we can overtly show we are justifying our choices with the language we use.

One way of doing this is to consider the problem or issue requiring attention, the solution and then the rationale or justification for the solution (the ‘why’). This sets the rationale (the reason) within a context.

A diagnostic assessment determined that the students required more attention to addition and subtraction of mixed fractions. This activity intends to address this problem by having the children engage with the task with blocks before it is done with figures. The reason I chose to do this is because students have higher comprehension levels when presented with visual or tangible representations of abstract problems (Benson, 2016). I also did this as I wanted to allow the children to ‘play’ with maths, to see that it can be a fun activity and in doing so, to breakdown some of the ‘anti-mathematics prejudices’ that Gaines (2017, p. 4) talks about.

The important thing here is the language used to signal the rationale , in this case:

The reason I chose to do this is because … and I also did this as …

Another problem / solution / rationale example:

Scaffolding is the support provided by the teacher or a significant other, such as a classmate, which helps students in learning (Gibbons, 2015). Some students were having difficulty with the language at entry while others, particularly those who had completed the pre-tasks, had few problems. Therefore, in order to address this disparity in level and understanding, mixed-ability pairs were created where the more competent student helped the other. On reflection, this was an effective way to run the activity for two reasons : it allowed peer-to-peer teaching which solidified both students’ understanding; and it scaffolded the support in a way that allowed me to roam the room lending advice to pairs as needed.

The language used to signal our rationale in this example:

in order to and for two reasons …

Language to signal rationale

in order to

the reason this was done/chosen …

for the following reason(s) …

for two/three reasons …

Language for further justification - showing importance

This was important / significant because …

This meant that I could…

This enabled me to …

… which enabled / allowed me to…

… which pointed to / highlighted that / showed me that …

The key thing to remember about rationale writing is to stand back from the writing, look at it in a big picture sense and ask yourself, ‘ Have I explained why? ’ If that is clearly articulated, you have provided a rationale.

How to Write a Rationale: A Guide for Research and Beyond

Ever found yourself scratching your head, wondering how to justify your choice of a research topic or project? You’re not alone! Writing a rationale, which essentially means explaining the ‘why’ behind your decisions, is crucial to any research process. It’s like the secret sauce that adds flavour to your research recipe. So, the only thing you need to know is how to write a rationale.

What is a Rationale?

A rationale in research is essentially the foundation of your study. It serves as the justification for undertaking a particular research project. At its core, the rationale explains why the research was conducted or needs to be conducted, thus addressing a specific knowledge gap or research question.

Here’s a breakdown of the key elements involved in crafting a rationale:

Linking Background to Research Question: 

The rationale should connect the background of the study to your specific research question. It involves presenting and discussing existing data on your topic, identifying gaps or issues in the current understanding, and explaining why addressing them is important​.

Objectives and Significance: 

Your rationale should clearly outline your research objectives – what you hope to discover or achieve through the study. It should also emphasize the subject’s significance in your field and explain why more or better research is needed​.

Methodological Approach: 

The rationale should briefly describe your proposed research method , whether qualitative (descriptive) or quantitative (experimental), and justify this choice​.

Justifying the Need for Research: 

The rationale isn’t just about what you’re doing and why it’s necessary. It can involve highlighting methodological, contextual, or conceptual limitations in previous studies and explaining how your research aims to overcome these limitations. Essentially, you’re making a case for why your research fills a crucial gap in existing knowledge​​.

Presenting Before and After Research: 

Interestingly, the rationale can be presented before and after the research. Before the research, it forms a central part of the research proposal, setting out the plan for the work. After the research, it’s presented in a research article or dissertation to explain the focus on a specific research question and link it to the study’s aims and outcomes​.

Elements to Include: 

A good rationale should include a summary of conclusions from your literature review, identify what is currently unknown, discuss inconclusive or contested results from previous studies, and emphasize the necessity to improve or build on previous research​.

Creating a rationale is a vital part of the research process, as it not only sets the stage for your study but also convinces readers of the value and necessity of your work.

How to Write a Rationale:

Writing a rationale for your research is crucial in conducting and presenting your study. It involves explaining why your research is necessary and important. Here’s a guide to help you craft a compelling rationale:

Identify the Problem or Knowledge Gap: 

Begin by clearly stating the issue or gap in knowledge that your research aims to address. Explain why this problem is important and merits investigation. It is the foundation of your rationale and sets the stage for the need for your research.​

Review the Literature: 

Conduct a thorough review of existing literature on your topic. It helps you understand what research has already been done and what gaps or open questions exist. Your rationale should build on this background by highlighting these gaps and emphasizing the importance of addressing them​​​​.

Define Your Research Questions/Hypotheses: 

Based on your understanding of the problem and literature review, clearly state the research questions or hypotheses that your study aims to explore. These should logically stem from the identified gaps or issues.

Explain Your Research Approach: 

Describe the methods you will use for your research, including data collection and analysis techniques. Justify why these methods are appropriate for addressing your research questions or hypotheses​​.

Discuss the Potential Impact of Your Research:  Explain the significance of your study. Consider both theoretical contributions and practical implications. For instance, how does your research advance existing knowledge? Does it have real-world applications? Is it relevant to a specific field or community?​

Consider Ethical Considerations: 

If your research involves human or animal subjects, discuss the ethical aspects and how you plan to conduct your study responsibly​.

Contextualise Your Study: 

Justify the relevance of your research by explaining how it fits into the broader context. Connect your study to current trends, societal needs, or academic discussions​​.

Support with Evidence: 

Provide evidence or examples that underscore the need for your research. It could include citing relevant studies, statistics, or scenarios that illustrate the problem or gap your research addresses​.

Methodological, Contextual, and Conceptual Limitations: 

Address any limitations of previous research and how your study aims to overcome them. It can include methodological flaws in previous studies, changes in external factors that make past research less relevant, or the need to study a phenomenon within a new conceptual framework​.

Placement in Your Paper: 

Typically, the rationale is written toward the end of the introduction section of your paper, providing a logical lead-in to your research questions and methodology​​.

By following these steps and considering your audience’s perspective, you can write a strong and compelling rationale that clearly communicates the significance and necessity of your research project.

Frequently Asked Questions:

What makes a good research rationale.

A good rationale clearly identifies a gap in existing knowledge, builds on previous research, and outlines why your study is necessary and significant.

How detailed should my literature review be in the rationale?

Your literature review should be comprehensive enough to highlight the gaps your research aims to fill, but it should not overshadow the rationale itself.

Conclusion: 

A well-crafted rationale is your ticket to making your research stand out. It’s about bridging gaps, challenging norms, and paving the way for new discoveries. So go ahead, make your rationale the cornerstone of your research narrative!

Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.

Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).

This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.

I honestly can't wait to work in many more projects together!

How to write the Rationale for your research

By charlesworth author services.

The rationale for one’s research is the justification for undertaking a given study. It states the reason(s) why a researcher chooses to focus on the topic in question, including what the significance is and what gaps the research intends to fill. In short, it is an explanation that rationalises the need for the study. The rationale is typically followed by a hypothesis/ research question (s) and the study objectives.

When is the rationale for research written?

The rationale of a study can be presented both before and after the research is conducted. 

• Before : The rationale is a crucial part of your research proposal , representing the plan of your work as formulated before you execute your study.
• After : Once the study is completed, the rationale is presented in a research paper or dissertation to explain why you focused on the particular question. In this instance, you would link the rationale of your research project to the study aims and outcomes.

Basis for writing the research rationale

The study rationale is predominantly based on preliminary data . A literature review will help you identify gaps in the current knowledge base and also ensure that you avoid duplicating what has already been done. You can then formulate the justification for your study from the existing literature on the subject and the perceived outcomes of the proposed study.

Length of the research rationale

In a research proposal or research article, the rationale would not take up more than a few sentences . A thesis or dissertation would allow for a longer description, which could even run into a couple of paragraphs . The length might even depend on the field of study or nature of the experiment. For instance, a completely novel or unconventional approach might warrant a longer and more detailed justification.

Basic elements of the research rationale

Every research rationale should include some mention or discussion of the following: 

• An overview of your conclusions from your literature review
• Gaps in current knowledge
• Inconclusive or controversial findings from previous studies
• The need to build on previous research (e.g. unanswered questions, the need to update concepts in light of new findings and/or new technical advancements). 

Example of a research rationale

Note: This uses a fictional study.

Abc xyz is a newly identified microalgal species isolated from fish tanks. While Abc xyz algal blooms have been seen as a threat to pisciculture, some studies have hinted at their unusually high carotenoid content and unique carotenoid profile. Carotenoid profiling has been carried out only in a handful of microalgal species from this genus, and the search for microalgae rich in bioactive carotenoids has not yielded promising candidates so far. This in-depth examination of the carotenoid profile of Abc xyz will help identify and quantify novel and potentially useful carotenoids from an untapped aquaculture resource .

In conclusion

It is important to describe the rationale of your research in order to put the significance and novelty of your specific research project into perspective. Once you have successfully articulated the reason(s) for your research, you will have convinced readers of the importance of your work!
