Classroom interaction in teaching is based on the expansion of interaction theory. It exists in multiple dimensions. It not only manifests itself in the interaction between the teaching subjects, but also in different levels such as classroom discourse and classroom activities, as well as in social culture. Among them, the interaction between the teaching subjects not only includes the execution of the activities in the class, but also includes the pre-class teaching preparation and the post-class teaching evaluation process. It is an all-round, multi-angle interactive concept.
