Secondly, choose appropriate research methods. The main research methods are: observation, investigation and experiment. Thirdly, it is to analyze the problem and study the causes of the problem. Explain clearly how you intend to deal with this problem. This is your research method.

research methods can be used from the perspective of teachers to solve the problems existing in the subject and get the most appropriate research results. That is, using the existing research methods, the research content is explained in a targeted and systematic way, including in-depth understanding of the problem, definition of concepts, research assumptions and general connections. At the same time, we can also extract typical cases in the study to support the research conclusions and make readers have new thoughts and associations. This paper gives a comprehensive description of the correct viewpoints, theoretical derivation process and substance obtained in the research, and puts forward new insights and new breakthroughs in this field.
