The traditional teaching model of the flipped classroom is that the teacher teaches in the classroom and arranges homework, and lets the students go home to practice. Different from the traditional classroom teaching mode, under the “flipped classroom teaching mode”, students can complete knowledge learning at home, and the classroom becomes a interaction place between teachers and students, and between students and students, including answering questions and knowledge. Use this teaching method to achieve better educational results..

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. Most videos are only a few minutes long, while longer videos are only ten minutes. Each video addresses a specific problem, is highly targeted and easy to find. 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.

Instructional video clearly defines Salman Khan’s instructional video. There is a notable feature of Salman Khan’s instructional video.

It feels intimate, like we are sitting at a table, studying together and writing down content on a piece of paper. “This is the difference between the “flipped classroom” instructional video and the traditional instructional video. The appearance of the teacher’s avatar and various items in the classroom in the video will distract students, especially the student’s autonomy.

Reconstructing the learning process Generally, the learning process of students is divided into two stages: the first stage is “information transmission”, which is achieved through the interaction between teachers and students, and students and students; the second stage is “internalized absorption” It is done by the students themselves after class. 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. Some achievements. “Flipped classroom” reconstructs students Learning process.

“Information transmission” is carried out before class. The teacher not only provides videos, but also provides online tutoring. “Enhanced internalization” is accomplished through classroom interaction. Teachers can understand the learning difficulties of students in advance. Effective tutoring in the classroom and mutual exchanges between students help to promote the internalization of student knowledge.
