(1) Thematic style
Organize and discuss the topics you want to study, and put all related issues under different headings. After sorting out and analyzing, connect the different headings.
(2) chronological order.
Starting from the earliest information, we can describe the historical evolution, the former situation and the future development trend vertically, so we can clearly see the ins and outs of this topic and describe the development direction of the topic in a hierarchical way. Before searching and downloading documents, we should also follow the following.
Principle:
● See the abstract for the topic and the full text for the abstract.
● There are documents that you want to trace back in the article, and you have not checked the references.
●pub med will also list the highly similar documents below and screen them according to 12.
Writing steps of Literature Review:
First, an overview of existing literature
In the following two common orders:
1. Thematic order: it is suitable for a wide range of literature reviews covering multiple topics.
2. chronological order: suitable for summarizing the historical evolution and development of a theme.
Second, demonstrate the Research Gap
1. Identify the limitations of previous studies: summarize and summarize previous studies and find out the shortcomings, which may be the limitations of research methods, research objects and research scope.
2. Put forward your own research questions: put forward questions that can fill the gaps in previous studies and solve existing problems.
3. Combining the above two points, we can prove the existence of Research Gap.
III. Conclusion
1. point out the Research Gap: point out its importance and possible impact, and also give suggestions and future research directions.
2. Emphasize the contribution: clearly point out the contribution made by this literature review.
3. Summary: Summarize the issues or topics studied in the literature review concisely and provide answers or conclusions.
Literature review Pay attention to lightning protection points:
(1) don’t write what you see. To write a literature review, you must first sort out your notes to find out the connection between documents, introduce, summarize, point out the shortcomings and the connection with your own articles;
Don’t write your own subjective evaluation directly, but learn to critically evaluate an argument with other people’s views. In this process, I play the role of an observer and interpreter of academic disputes;
④ Don’t write Literature review as a general esay/paper, and focus on expressing your own opinions, but summarize the literature.
⑤ Look for typical documents, and don’t analyze some irrelevant documents, which have little to do with topic, which will make the whole literature review seem meaningless.
