Research Gap Statement Generator

How to Use the Research Gap Statement Generator

1. 1. Choose the gap type. Pick the one that best describes what is missing — studies conflict, a question is unasked, a group is left out — and read its one-line description. If two fit, run the tool twice and keep the stronger statement.
2. 2. State what research has established. Write a clause that completes “Research has established that…”, with a citation. This sets up the “however” that follows.
3. 3. Name the gap and say why it matters. The label and placeholder change with the type. Then say what the gap prevents: a gap nobody needs filled is not a reason to do a study.
4. 4. State what you will do. Start with a verb, and add a setting if you have one. Copy the statements, and keep your search notes in the last box for your methods.

How a Gap Statement Works

John Swales’ Create-a-Research-Space model, summarised in the USC library’s guide to the CARS model, describes an introduction in three moves: establish the territory, with the importance of the topic and a review of earlier work; establish a niche; and occupy the niche. A niche can be established by counter-claiming, indicating a gap, raising a question, or continuing a tradition. The generator’s three sentences are those moves in miniature: territory (“Research has established that…”), niche (“However…”), and consequence (“This matters because…”), with the purpose statement occupying the niche.

Seven Types of Research Gap

The types follow the taxonomy of seven gaps in Miles (2017), a doctoral-workshop paper that builds on Robinson and colleagues (2011) and Müller-Bloch and Kranz (2015). The categories overlap, and later authors have questioned how sharply some can be told apart, so choose the one that helps you say what is missing and do not agonise over the label.

Worked Example: A Population Gap

“Try an example” loads a population gap in the study of peer tutoring used elsewhere on this site. The citation and the search record are placeholders. These are the two statements the tool writes, 80 words in all:

Each of the writer’s clauses sits inside a fixed frame, so every sentence is the writer’s claim in the tool’s connecting words. The tool cannot tell whether the gap is real. That is what the last box is for: a gap is only as good as the search behind it.

Common Mistakes with Research Gaps

• “No study has ever examined…” One overlooked paper disproves it. Write “few studies” or document your search, and see the checklist’s flag.
• A gap that nobody needs filled. Missing is not the same as worth knowing. The consequence sentence is there to make you say why it matters.
• Confusing the gap with the problem. The problem is what goes wrong in the world; the gap is what research has not yet told us about it. The Problem Statement Generator covers the first.
• A purpose that does not answer the gap. Read the two statements together: if the purpose could follow any gap, it is not tied to this one.
• Claiming to fill the whole gap. One study narrows a gap. Say what part of it yours addresses.

Frequently Asked Questions

What is a research gap?

A research gap is something the existing literature does not yet tell us: an unanswered question, conflicting findings, a group or setting that was not studied, a method that limits what can be shown, or a claim that has not been tested. It becomes a justification for a study only when filling it matters.

How do you write a research gap statement?

Say what is established, introduce the gap with a contrast word such as “however”, say why the gap matters, and then state your purpose. The generator follows that order, which mirrors the first three moves of Swales’ model of an article introduction.

How do I find a research gap?

Read recent reviews and the limitations and future-research sections of key papers, then search for what they say is missing. Track the citations of the central studies, and note who and what is not represented. The Literature Review Matrix Generator helps you compare studies side by side.

What is the difference between a research gap and a research problem?

The problem is the practical or scholarly issue that needs addressing; the gap is what existing research has not yet established about it. A problem statement describes the first and a gap statement the second, and many introductions need both.

What is the difference between a gap statement and a purpose statement?

The gap statement says what is missing and why it matters. The purpose statement says what your study will do about it, usually in a single sentence that begins with a verb. Together they form the bridge between the literature review and your research question.

How do I prove that a research gap exists?

You show the search that did not find the answer: databases, search terms, date range and screening. Reviewers may check, so keep the record. A claim that nothing has been written is easy to disprove, while “few studies” with a documented search is easy to defend.
