William james, a professor at Harvard University, found that if a person has no motivation, he can only play 20% ~ 30% of his ability; If you are properly and fully motivated, you can play to 80% ~ 90% or even higher. In the teaching process, students with similar abilities often get different grades, and even students with poor abilities may get better grades than those with strong abilities. There are many reasons, but the main reason is that the degree and effect of incentives are different. Under the background of quality education, the traditional mathematics teaching methods in middle schools can't adapt to the development of the times and can't effectively improve students' learning enthusiasm. Through certain incentives, students' learning enthusiasm can be improved and students can be guided to actively participate. Therefore, it is very important to motivate students correctly and fully and give full play to their abilities.

First, mathematics is a very flexible subject, so we can't simply teach the "dead" knowledge in this book. We should encourage students to explore more. Actively cultivate students' interest in learning. Only when you are interested can you have hobbies. Practice if you like, and enjoy if you like. Because you are interested, you will have the initiative and enthusiasm to learn. In mathematics learning, we turn this spontaneous perceptual pleasure into a conscious and rational "understanding" process, which will naturally become the determination to learn mathematics well and the success of mathematics learning.

Second, actively organize effective mathematics activities and practice the learning process.

1. In teaching, teachers let children operate freely, fiddle, experiment, observe and think, know things by themselves, find problems and get answers. Through students' active activities, we gradually discover the law and generalize and conceptualize the meaning.

2. Mathematics learning is a personalized and diversified learning. Students should experience mathematics exchange activities as much as possible in the process of learning, so that they can feel other people's thinking methods and processes in the activities, thus changing their cognitive style and promoting all-round development.

Third, multi-layer feedback, effective regulation and moderate evaluation.

The content of each class is different and the students' foundation is different, so the requirements for students in each class should be different. In class, we should pay more attention to the reaction of students with learning difficulties, allow different methods and opinions to top students, encourage middle school students to do right and well, pay special attention to their progress and praise them appropriately to build their self-confidence.
