I don't agree, because some students indulge themselves, but the teacher wants to control them but can't. It is better to change this sentence to: there are no unqualified children, only unqualified parents. Because parents are their children's first teachers, their behavior affects their children. I agree that teachers' attitudes and teaching methods affect students. As long as the teacher tries his best, the students will be much better than they are now.

2. How to find the bright spot of "poor students"?

People who fight generally have a sense of collective honor. He is eloquent and can perform programs. Those who don't study well love labor. If you don't like homework, secretly force him to finish it, and then praise him in public, saying that he finished it on his own initiative. Slowly discover and carefully observe, there will always be many opportunities, and you can also create your own opportunities.

Do you approve of corporal punishment?

No, more than half of high school students are adults, and they care more about face and can't lose face in public. In my opinion, sometimes "cold violence" can be used. Once students feel neglected, they will feel worse than the teacher's class, and then go to education and guidance.
