Using video for teaching, people have been studying it many years ago. In the 1950s, radio and television education in many countries around the world are evidence. Why did past explorations have little effect on the traditional teaching model, and “flipped classroom” has received a lot of attention? This is because the “flipped classroom” has the following different characteristics. Salman Khan’s instructional video is short and detailed. Whether it is a math tutorial video by Jonathan Berman or a chemistry teaching video by Aaron Sams and Salman Khan, a common feature is very brief.

The length of the video is controlled within the time range of the student’s concentration, which is consistent with the characteristics of the student’s physical and mental development; the video has multiple functions such as pause and playback, which can be self-controlled, which is conducive to the independent learning of students.

Due to the lack of support from teachers and help from peers, the “absorption and internalization” stage often makes students feel frustrated, lose motivation and consciousness.
