In response to the long-standing passive learning state in classroom teaching where students are used to being arranged and waiting to listen to lectures, it is noted that the solidification of this state will severely weaken the active thinking of students, encourage unconfidence, and cause problems in solving problems. In the process, we pay too much attention to the final explicit results and ignore the bad guidance of implicit thinking methods; on the other hand, paying attention to the development of the times and social needs require classroom teaching to keep pace with the times.
