Before writing a thesis, we should collect information, including research work and reading relevant literature, and make a certain analysis of the research object. Summarize your own views and discuss around the central idea.

The topic selection only determines a macro scope, and the broad theme should be reduced to an easy level. The scope of the topic depends on the content of the study, and the size of the scope should be adapted to the number of teaching research objects and research events. For a topic with too large a scope, you can limit it to the boundary and get its branches. Analysis is to decompose a complex research problem, that is, to decompose a complex research problem into several interrelated small problems according to the internal logical relationship, and then break them one by one; Or analyze the relationship between the elements of the problem, so as to simplify and clarify the study of the problem, that is, analyze the cause and effect of the problem, find the internal relationship of the problem, and thus grasp the root of the problem deeply and accurately.
