Flipping the classroom is based on

Flipping the classroom is based on traditional classroom teaching. It is a teaching mode in which students can learn on their own before class, and teachers can help students master knowledge by organizing relevant discussions and appropriate training programs in class. This teaching mode is called "flipped classroom" , because it is different from the previous teaching mode, in which the teacher first teaches the knowledge in the classroom, then the students review and consolidate the knowledge after class. The flipped classroom model has two characteristics: First, it is more flexible in space and time arrangement, not limited to fixed classroom and specific opening time, effectively reducing teachers'teaching time, and promoting students'autonomous learning. Second, the roles of teachers and students have changed. In the original teaching model, the teacher was the center of the teaching activity, while the flipped classroom was student-centered. Student-centered teaching promotes students'active learning and exploration, which is superior to traditional teaching methods.
