Slow pace, that is to say, he didn't preview the class he is going to attend today, and his understanding ability is not very good. In the formal class, the teacher talked about knowledge point A. He: ... huh? He hasn't digested knowledge point A, and the teacher is already talking about knowledge point B. He is busy looking at knowledge point B and has been kicked out. Turns out he doesn't understand abcd at all.
The solution is to effectively supervise the preview, and it is wrong to supervise the homework. Many teachers think that since there is no teaching, it is understandable that students can't do it, but in fact, the knowledge in primary and secondary schools is not that complicated. Even if students don't understand, correcting mistakes will be much more profound.
As for being too passive, I just don't take the initiative to think and "add meals" to myself. Well, it's just laziness ... try to let them take the initiative, for example, let students talk about new knowledge, for example, let students talk about the answers revised after the exam, for example, let students summarize the key points of the exam. However, this requirement has a platform for students to acquire knowledge to solve puzzles, such as teachers, good students, or teaching AIDS. Teachers also need to assign tasks in advance, so that students can come down and prepare. Finally, it will greatly reduce the role of teachers in the classroom. Accurately speaking, the teacher's role has changed from spreading knowledge to doing PPT, checking and filling gaps, and supervising.
Of course, poor students after junior high school can't avoid poor foundation. We should make up for this and then talk about other things.
