For such a student, we should be more patient, talk to her alone, and give her some reason from her interest.

Sister's identity

"I talk to you today. It's not the teacher's student status, but my sister sees that she doesn't work hard, so sometimes she is particularly angry. I am not much older than you, am I? "

Timely response situation

In this case, of course, students who are really naughty will report the situation to the school in time. When she doesn't make a big mistake, you can make a mountain out of a molehill and say that she is too naughty to show the school that you are still willing to pay more attention to this child. Once or twice, the school will understand that this student is not easy to teach and will understand your difficulties.
