what is research gaps ?

Research gaps
If you are working on original research, you will want to identify a need for your research somewhere close to the beginning of your paper. Why? Because you will want to show the reader that you are not duplicating existing research.In other words: this paper is worth reading! This is best done by surveying the current research and then identifying a gap that you are going to fill.  

A common sequence for introductions in an academic journal article is- 

1. Establish the field: Identify the broad problem and state its importance.
2. Summarize previous research: State what is significant in what has already been written.
3. Create a research space: Describe the gap you propose to fill in the existing research literature. This then creates an opportunity for you to make a contribution to the research in the area.
4. Introduce your research project: Establish your research thesis or questions.
(The above headings derive from a scheme proposed by Swales, 1981, quoted in Bruce, 1995).

In the following example notice how the writer pays a complement to existing work ('There have been a number of valuable studies of self-employment...') and then identifies the gap ('However, none of these studies provides...')
Research Gap identified: A study of the changes over the last decade.

There have been a number of valuable studies of self-employment using cross-section data (Rees and Shah, 1986; Blanch flower and Oswald, 1993; Taylor, 1996), all of which present evidence on a number of employment and personal characteristics on the sector. However, none of these studies provides a picture of the changes over the last decade or forecasts the trends in self-employment as the recession of 1990 took hold.

Research Gap identified: The effects of pit closure on women's lives.

While there has been some research on the general impact of female unemployment (Coyle,1984; Popay,1985), little has been written about the effects of pit closure on women's lives.
