Mathematics was originally very interesting. But the students didn't find it. If their grades get better and better, they will become more and more confident. I think it's interesting. So quizzes are necessary. score But the problem should not be too difficult, and most students can do it. In addition, one or two difficult questions can be attached later. Of course, no matter how difficult the problem is, it can't be counted in the total score. You can tell the students that if you try to get the following questions right, it means that you are talented in mathematics. Very promising. Everyone likes to be praised, and if you praise it, you will be motivated. In addition, from my own personal experience, students don't want their parents to be disappointed in him. They want their parents to be full of hope for them. So, you can make a list, record each student's grades, list the students who have made progress as potential students, visit their homes, and tell their parents how motivated and amazing the child is. You have been to their home in person, which shows that their children are very concerned and they will pay attention.
