1. Teacher-centered communication mode The characteristics of this mode: under the control of teachers, they mainly learn from books, and the knowledge and information in textbooks are mainly transmitted and received. There are five common teaching methods: organizing teaching, checking and reviewing, teaching new textbooks, consolidating new textbooks and assigning homework. This communication mode attaches importance to the leading role of teachers, but ignores the main role of students, attaches importance to the teaching of book knowledge, but ignores the cultivation of ability.

2. Student-centered communication model This model is characterized by taking personal life practice or direct experience as the learning center and learning from activities. This way of communication attaches importance to students' initiative and personal experience, but ignores the leading role of teachers and the teaching of systematic book knowledge.

3. Problem-centered communication mode This mode is characterized by learning from discussion, which can inspire people to explore, but it is easy to make teaching lack of systematicness. The above three models have their own advantages and disadvantages, so they should be used flexibly in teaching communication.
