Classroom teaching is the main way of school education. With the development of learning theory and information technology, more and more people realize that different theories and methods should be integrated in the classroom, instead of just relying on the theories and methods of a school or using traditional single media means. In recent years, under the guidance of modern educational theory, many teachers have carried out innovative research and practice of "learning"-centered classroom teaching mode, integrated information technology into subject teaching, and combined the whole class teaching method with demonstration method, group cooperative learning discussion method and individual-oriented multimedia stylized teaching method. The new classroom teaching abandons the teacher's "centralized teaching" and greatly increases students' time in class activities, which is refreshing. At the same time, many primary and secondary schools in China have built multimedia network classrooms, and classroom online teaching has become a new thing in education, providing a new stage for educators to carry out teaching reform and innovation.
