How to resolve the literature gap from literature review?
Feb 05, 2024
Focusing on a research journey can be an impossible task as one delves into the vast expanse of existing literature. Yet, pinpointing problems in this vast sea of knowledge can prove to be quite difficult. In this blog post, we'll look into effective techniques for addressing gaps in your literature review, so that your research can make a valuable contribution to your field.
What is Research Gap?
A research gap refers to a deficiency, unexplored area, or unanswered question in the existing body of knowledge within a particular field of study. It represents a space or void in the current literature where further investigation, analysis, or exploration is needed. Identifying and addressing research gaps is a crucial aspect of academic research as it allows researchers to contribute new insights, knowledge, or solutions, thereby advancing the understanding of a subject or field.
Researchers typically identify research gaps during the literature review phase of their study. This involves reviewing existing literature to understand what is already known about a topic and pinpointing areas where there is insufficient information, conflicting findings, or where no research has been conducted. Addressing these gaps becomes the focus of the new research, allowing the study to contribute to the scholarly conversation and expand the current understanding of the subject matter.
For example, let’s say your research aims to identify the cause (or causes) of a particular disease. Upon reviewing the literature, you may find that there’s a body of research that points toward cigarette smoking as a key factor – but at the same time, a large body of research that finds no link between smoking and the disease. In that case, you may have something of a research gap that warrants further investigation.
Now that we’ve defined what a research gap is – an unanswered question or unresolved problem
– let’s look at a few different types of research gaps.
- The classic literature gap
- The disagreement gap
- The contextual gap, and
- The methodological gap
The Classic Literature Gap:
Definition: The classic literature gap is a term used to describe a scenario where there is a noticeable absence of thorough or fundamental research on a specific subject or matter.
Characteristics: There is often a lack of widely recognized, important writings that thoroughly delve into and establish a strong basis for comprehending the topic.
Significance: Identifying a classic literature gap indicates the need for foundational research to establish a strong base of knowledge in the area.
The Disagreement Gap:
Definition: The variation arises when the current body of literature presents contrasting results, explanations, or perspectives on a particular aspect of a subject.
Characteristics: There is a gap in the research where researchers have differing opinions and inconsistencies regarding important aspects, results, or theories in this subject.
Significance: Addressing the disagreement gap may involve resolving conflicting evidence, clarifying methodologies, or synthesizing diverse perspectives to contribute to a more cohesive understanding.
