Learn to Demonstrate a Research Gap in Dissertation Chapter 2
Stuck on dissertation chapter 2? Learn to identify and demonstrate a clear research gap in your literature review chapter with examples and a free checklist.
Introduction
If you are thinking, “I am stuck at Chapter 2,” you are not alone. Many doctoral candidates struggle with dissertation chapter 2, especially when trying to clearly demonstrate a research gap. The literature review chapter is not just a summary of existing studies—it is the intellectual foundation that justifies your entire dissertation.
Your committee is not asking you to rewrite what other scholars have said. They want you to:
- Critically analyze existing research
- Identify patterns and contradictions
- Highlight limitations
- Clearly demonstrate what is missing
That “missing piece” is your research gap.

H2: Annotated Section 1 – Understanding the Purpose of Dissertation Chapter 2
What should be written in Dissertation Chapter 2?
Dissertation chapter 2 is your literature review chapter, and its purpose is to:
- Establish theoretical foundations
- Review prior empirical research
- Identify methodological trends
- Reveal inconsistencies or unresolved issues
- Demonstrate a clearly defined research gap
If your committee says, “I don’t see the gap,” it usually means one of three things:
- You summarized instead of synthesized
- You did not compare studies
- You failed to articulate what is missing
What Is a Research Gap?
A research gap is:
- An unanswered question
- A limitation in methodology
- A population that has not been studied
- A conflicting finding not resolved
- A theoretical framework not applied in a specific context
In dissertation chapter 2, your goal is not just to find a gap — it is to demonstrate it logically and convincingly.
Annotated Example (Weak vs Strong Gap Demonstration)
Weak Example (Summary Only):
Smith (2020) studied leadership styles in small businesses. Johnson (2021) examined employee engagement in startups. Brown (2022) explored innovation performance in SMEs.
This is a summary. There is no synthesis. No gap.
Stronger Example (Synthesis + Gap Identification):
While Smith (2020) examined leadership styles in small businesses and Johnson (2021) investigated employee engagement in startups, neither study explored how transformational leadership influences innovation performance in minority-owned SMEs. Additionally, Brown (2022) focused on innovation outcomes but did not assess leadership style as a predictor variable. Therefore, limited research examines the intersection of transformational leadership and innovation performance within minority-owned SMEs.
Now the research gap is visible.
The Structure of a Strong Literature Review Chapter
Your literature review chapter should include:
- Theoretical framework discussion
- Thematic organization
- Critical comparison
- Methodological critique
- Identified research gap
A strong dissertation chapter 2 reads like an argument, not a book report.
H2: Annotated Section 2 – Step-by-Step Process to Demonstrate a Research Gap
If you are stuck at chapter 2, follow this systematic method.
Step 1: Conduct Comprehensive Database Searches
Use high-quality academic databases such as:
EXTERNAL_LINK_1_HERE – Scopus (Research Database Access):
https://www.scopus.com
Scopus allows you to:
- Identify high-impact journals
- Analyze citation patterns
- Track emerging research trends
- Review abstracts before downloading full papers
You should search using combinations of:
- Primary construct
- Context
- Population
- Methodology
Example search query:
“Transformational leadership” AND “innovation performance” AND “SMEs”
Step 2: Organize by Themes, Not Authors
In dissertation chapter 2, do not organize by individual authors. Instead, organize by themes:
- Theme 1: Leadership Theories
- Theme 2: Innovation Performance Models
- Theme 3: SME Organizational Context
- Theme 4: Empirical Studies Combining Variables
The gap becomes visible when you compare themes side-by-side.
Step 3: Identify Patterns and Contradictions
Ask:
- Are findings consistent?
- Are certain populations underrepresented?
- Are methods outdated?
- Are geographic regions missing?
- Are theoretical lenses limited?
Your gap often appears when:
- Most studies are quantitative, but qualitative insight is missing
- Most research focuses on large corporations instead of SMEs
- Studies are U.S.-centric but ignore global markets
Step 4: Use “However” and “Although” Strategically
Your language matters in dissertation chapter 2.
Use phrases like:
- However, limited research examines…
- Although prior studies have explored…, few have considered…
- Despite extensive research on…, little attention has been given to…
- Existing literature fails to address…
These transitions signal critical thinking.
Step 5: Connect the Gap to Your Study
A research gap must lead directly to:
- Your research questions
- Your hypotheses (if quantitative)
- Your conceptual framework
Example:
Given the limited research examining transformational leadership and innovation performance in minority-owned SMEs, this study seeks to explore…
That is alignment.
H2: Tips – How to Avoid Common Chapter 2 Mistakes
If you are stuck at chapter 2, you may be making one of these common mistakes.
Mistake 1: Writing a Summary Instead of a Synthesis
Your literature review chapter must compare, contrast, and critique — not summarize.
Mistake 2: Claiming a Gap Without Evidence
Never say:
“There is little research…”
Instead, show it through citation analysis.
Mistake 3: Choosing a Gap That Is Too Broad
Bad Gap:
“There is limited research on leadership.”
That is inaccurate.
Better Gap:
“Limited research examines transformational leadership’s impact on innovation performance in minority-owned SMEs within emerging economies.”
Specific = defensible.
Mistake 4: Ignoring Recent Studies
Most committees expect literature within the last 5–7 years unless foundational.
Use Scopus filters to ensure recency.
