Equipment technical support must be in place first. If the teacher's experience is not good, we can also imagine the students' acceptance, and the teaching quality of an online class will be greatly reduced. At the same time, those mature live classes with many years' teaching experience have been polished for many years, from the cultivation of teachers' resources, to the standardization of teachers' teaching style, to the selection of course content and classroom design, the teaching quality is better.

If the platform is stable and the technical equipment is in place, the live class can only be considered qualified, which is far from reaching the mature standard. In Zhang Hua's view, a mature live broadcast class must be able to compete directly with Tik Tok and games. Because "classroom discipline" is not very controllable for the teachers who attend the live class, I wonder if the students at the other end of the screen touch out the iPad while listening to the class. Therefore, under the premise of imparting knowledge, the live broadcast class must be able to mobilize students' enthusiasm and interest in more ways, so that students can truly achieve something. This is what a mature live broadcast class should do.

When talking about teaching methods that can arouse students' interest, Zhang Hua believes that this is actually a considerable challenge to the course content design and teachers' teaching methods. Taking the teaching of mathematics as an example, this paper points out that we can start with daily life, such as anthropomorphic understanding of odd function and even functions, so that students can really listen to beautifully explained knowledge.
