When to Write an Introduction?

It is suggested by most of the researchers that the introduction section should be written just after the literature section and before the conclusion section as shown in Fig 2. Fig 2 denotes the order of writing all sections in a research paper. It is obvious to write this section in the below way because once you are aware of all literature then you can easily know the pitfall in that area.

  • The length of the introduction in the research paper depends upon the size of the research paper. If the research paper is from 5 to 7 pages of length, then the introduction can be ranging from 1 to 2 pages.
  • The content size inside the introduction section is shown in Fig 3. The major content in the introduction section is of background literature. The summary of the topic and summary of research work have almost the same content size. Lastly, the organization of paper is mentioned. A standard introduction section is of 4 paragraphs. Although it depends upon the researcher's understanding.

How to Write an Introduction?

The process of writing an introduction may vary from researcher to researcher. But an efficient introduction section must include at least four paragraphs. Each paragraph must target some important issues that a reader wants to know. Those issues are explained in the below table. 
  • The first paragraph introduces the research topic and research area. 
  • The second paragraph provides background information. It must cite the major limitations in those areas. 
  • The third paragraph must explain the main reason for doing that research by mentioning the importance and plan of the research. This paragraph should also include a thesis statement (hypothesis). 
  • The last (fourth) paragraph provides the structure of the research paper.
1. Introduce the research area and research topic: First of all, you have to briefly explain your broad research area. Then explain your research topic with its applications. This indirectly depicts the importance of your research topic. This explanation should be complete as well as brief.
2. Provide background information: Explain the background literature related to your research topic by specifically indicating the demerits/ gaps in the literature. Explain these gaps in the literature as these gaps needed to be targeted as the goal of the research work.
3. Provide a rationale for your work: Provide your reason to perform this research. Here you need to target the gaps in the previous literature and tell why these gaps needed to be filled.
4. Tell the importance of your research to the readers: Here you need to discuss the importance of your research work. Explain your reason why you are performing this research and how this research is helpful to mankind or human. Show the significance of your research.
5. Briefly explain the plan of research: Here you need to briefly explain your plan of action that you will perform to attain the goals of the objective. This plan of action should be explained in brief.
6. State your hypothesis: In the last, the explanation of proposed research should be made on the basis of limited evidence as a starting point for further investigation.
7. Organization of the research paper: Explain the organization/ structure of further sections of a complete research paper.


  • Explain the research area and research problem properly.
  • The content of the introduction should be original and fresh. It should not be copy-paste.
  • Explain all key terms/ abbreviations used in the research paper in this section only.
  • The length of the introduction is important. It should be decided as per the research paper size.
  • The connection between the limitation of background and proposed solution should be logically correct.
  • Do not explain too much. Try to maintain the content concisely.
  • The introduction should be interesting so that the new readers get engaged.
  • Use simple and well-written language.
  • All the content discussed in the introduction should be properly structured and well organized.
