2. How to write a literature review?
When writing a literature review, you can't just tell others what I have read, and you are opposed to saying no comments. It is necessary to explain the researchers' views on the research situation, provide some explanations for the conclusions of different studies, and transfer from one question to another logically and smoothly, and make it a guide for their broader or deeper research. It is necessary to clearly show that the research in the investigated field is not sufficient and needs to be expanded, and the need for further research in this field is put forward. Literature review should show the necessity of in-depth descriptive research. Perhaps a phenomenon has not been studied by qualitative methods, but in fact it is appropriate and useful to conduct qualitative research.
Although the literature should be quoted appropriately, don't make the literature review into a list of cited materials; Organize the literature review around the key points related to the problem, and don't just organize it in chronological order. There should be a conclusion at the end of this part, summarizing the previous investigation and synthesizing the key contents.
