Research Process

These pages offer an introduction to the research process at a very general level.

What is a ‘gap in the literature’?

The gap, also considered the missing piece or pieces in the research literature, is the area that has not yet been explored or is under-explored. This could be a population or sample (size, type, location, etc.), research method, data collection and/or analysis, or other research variables or conditions. For a more detailed definition, see the following:

How do you identify the gaps?

Conducting an exhaustive literature review is your first step. As you search for journal articles, you will need to read critically across the breadth of the literature to identify these gaps. You goal should be to find a ‘space’ or opening for contributing new research. The first step is gathering a broad range of research articles on your topic. You may want to look for research that approaches the topic from a variety of methods – qualitative, quantitative, or mixed methods. SAGE Research Methods Online, accessible on the Library’s A-Z Databases page, is an excellent source for learning about research methodology.

Using the search technique called nesting, you can add these words to your search and limit to the abstract of the articles to quickly identify research that uses different methods. To learn more strategies and how to take advantage of advanced search features in article databases, see the Library’s Research Methodology page.

Where can you locate research gaps?

As you begin to gather the literature, you will want to critically read for what has, and has not, been learned from the research. Use the Discussion and Future Research sections of the articles to understand what the researchers have found and where they point out future or additional research areas.

See this example below:

Continue to ask critical questions of your topic – who, what, when, where and how – about the population or setting, conditions or variables, methods or analysis, and measurement or outcomes. Also consider what has not been explored in the study and what may be a possible ‘gap’ or opening for your potential research and contribution to the topic. Use organizational tools such as charts or Venn diagrams to map out the research you find from scholarly articles. These methods may be helpful to organize what information you have found and what is shared among the literature, as well as to identify what areas may be missing in the research.

For additional examples, try a Roadrunner Search using this search string: ("Literature review") AND (gap*)
