In the process of teaching practice, we will find such a problem: the class is very enthusiastic and devoted, but the result is often disappointing. We often review our behavior, but we can't solve the problem fundamentally. In fact, teaching is a bilateral activity between teachers and students, so we have to think about whether there are some defects in the way students attend classes. From the concept of the new curriculum standard, we should not only change the traditional teaching methods, but also change the learning methods of a generation.
