Both theory and practice tell us that in order to give full play to the actual effectiveness of various teaching methods in the teaching process and achieve the purpose of optimizing the teaching process, we must first work hard on the optimization of teaching methods or the optimization design of teaching methods. The former refers to the rational choice of existing teaching methods, while the latter refers to the creation of new teaching methods. Whether it is "optimization" or "innovation", we should generally pay attention to the following four points: First, the choice or innovation of teaching methods must conform to the teaching laws and principles; Second, according to the teaching content and characteristics, to ensure the completion of teaching tasks; Thirdly, it must conform to students' age, psychological change characteristics and teachers' own teaching style; Fourth, it must conform to the existing teaching conditions and the prescribed teaching time. In addition, in guiding ideology, teachers should pay attention to examine various teaching methods from a dialectical point of view.
