Flip-over classroom model is a part of the great education movement, which overlaps with the teaching methods and tools such as blended learning and inquiry learning in meaning, in order to make learning more flexible and active, and to make students more involved. In the Internet age, students learn a wealth of online courses through the Internet without having to go to school to be taught by teachers. The Internet, especially the mobile Internet, gave birth to the "flip classroom" teaching model. "Flip classroom style" is a complete subversion of the traditional classroom teaching structure and teaching process based on printing, which will lead to a series of changes in teachers' roles, curriculum models and management models.
