Invert the model of learning in the classroom as a new model in the field of education as modern Internet technologies develop and the concept of learning is updated. It is widely used and promoted in various disciplines. Scholars and front-line teachers have begun to try to introduce the flipped classroom teaching model into language classrooms. With this opportunity, practical studies on flipping classes in foreign languages have emerged. At the same time, the study of the learning process in the classroom has become a problem that needs to be urgently addressed. At present, the linguistic field generally regards the specific teacher-student discourse interaction and verbal communication patterns in the teaching process as a research trend. For the Japanese teaching field, the research on the specific characteristics and patterns of teacher-student verbal communication in classroom discourse is a top priority. Drawing on previous research theories and research methods, the two key research topics are combined. Taking the foreign language curriculum under two different classroom teaching modes as the empirical research object, this paper studies the specific classroom teaching process by using the interaction theory of sociology. At the same time, it uses the Flanders Interaction Analysis System (FIAS) to conduct detailed quantitative research on the interaction of teachers and students in classroom discourse, and analyze and discuss the statistical results. The relevant teaching suggestions for the application of the Japanese flipped classroom teaching mode are put forward, and the problems that must be paid attention to in the practical application are pointed out, in order to provide meaningful reference and reference for the construction of the Japanese teaching mode.
