Interest is the starting point of knowledge, the source of motivation for students to learn and create, and the catalyst for success. In order to improve the quality of mathematics teaching, teachers must persist in stimulating students' interest, cultivate students' interest in learning mathematics purposefully and in a planned way, and make it lasting. So how to stimulate students' interest?

1, create problem situations, enliven the classroom atmosphere and stimulate interest in learning.

The teaching process is not only a process of learning cognition, but also a process of developing students' thinking. Teachers should be good at creating problem situations, stimulating students' interest in learning and guiding students to solve problems successfully through hard work. They must create a pleasant learning atmosphere and a good activity environment. Integrating mathematics knowledge into life practice can stimulate students' emotions and discover the mystery of mathematics. Make them realize that mathematics can not be separated from life, and life contains mathematical knowledge everywhere.

2. Optimize the teaching environment, improve teaching methods and stimulate students' interest in learning.

According to students' age characteristics and cognitive rules, make full use of students' curiosity and use various means to induce their desire for knowledge. Middle school students' logical thinking ability, understanding ability and imagination ability are gradually formed. In teaching, we should create some opportunities for students to think independently, cultivate students' ability to analyze, judge and summarize problems, show their skills and sublimate their interests.

3. Let students experience the joy of success and cultivate self-confidence.

When students succeed, they can have positive emotional experiences such as satisfaction, happiness and pride. We should seize the opportunity to praise and encourage them, especially the underachievers, and we should turn their positive emotions into learning, so as to improve their interest in learning.
