Criticize education severely
From their own point of view, it is not strict enough. They don't criticize and educate students every time because of their low grades. They just analyzed his test paper and told him to pay attention next time, but how can the students concentrate on the lecture?
Students' own reasons
He is not the kind of sinus that can't afford to help, which shows that his inner strength is insufficient. I really want to improve his grades, but his grades are always unstable and have not improved steadily.
Improve teaching style
Sometimes I wonder if I should let him change teachers and improve his teaching style to see if there will be any improvement. This idea has been in my mind for a long time, no, after all, I can't take her for the longest time without improvement.
Verify students' mastery.
Look at the mid-term exam, and you must improve this time! Next class, let him tell me a question on the test paper first. He says he can. Go and verify whether he can.
