1. The Classification of Teaching Methods in Academic Theory, edited by Professor Li Bingde, classifies the teaching methods commonly used in primary and secondary schools in China into five categories according to the external forms of teaching methods and the corresponding characteristics of students' cognitive activities in this form. The first kind of methods: "the method of transmitting information based on language", including teaching methods; Talking method; Discussion method; Reading instruction method, etc. The second method: "method based on direct perception", including demonstration method; Access methods, etc. The third method: "the method based on practice training", including practice; Experimental methods; Practice method. The fourth method: "teaching method based on appreciation activities", such as training method. The fifth kind of methods: "methods based on guided inquiry", such as discovery method; Query methods, etc.

2. Professor Huang Fuquan's hierarchical structure classification model Professor Huang Fuquan believes that from concrete to abstract, teaching methods consist of three levels, which are: the first level: principle teaching methods. It is the result that the methodology of teaching consciousness solves the direct connection between teaching laws, teaching ideas and new teaching theory concepts and school teaching practice in teaching practice. Such as: heuristic method, discovery method, design teaching method, injection method, etc. The second level: technical teaching methods. Upward can be guided by the principle teaching method, and downward can be combined with the teaching contents of different disciplines to form an operable teaching method, which plays an intermediary role in the teaching method system. For example: teaching method, talking method, demonstration method, visiting method, experiment method, practice method, discussion method, reading guide method, practice work method and so on. The third level: operable teaching methods. Refers to the specific methods with particularity in the teaching of different disciplines in schools. For example, the decentralized literacy method in Chinese class, the listening and speaking method in foreign language class, the sketching method in art class, the solfeggio method in music class and the working procedure method in labor technology class.
