The issue of urban and rural education equity has always been the focus of public attention. Synchronous classroom provides a possible way to achieve urban and rural education equity. It is of great practical significance to study the teacher-student interaction and how to carry out teacher-student interaction that can help synchronous classroom teaching. This paper takes Long feng Experimental Primary School and Sanjiang Central Primary School as an example, adopts video analysis and lag sequence analysis (LSA) to analyze the teacher-student interaction behavior, ratio, teacher's questioning and student's responses, teacher's classroom behavior, student's classroom behavior and interaction between teacher and student. It is found that strategies such as optimizing synchronous classroom teaching questioning, strengthening the collaborative lesson preparation and research between the main teachers and assistant teachers, timely adjusting the organization mode of synchronous classroom teaching under the teaching design of large units, and strengthening the application of information technology can be used to improve and promote the teacher-student interaction and effects in synchronous classroom.
