To arouse students' enthusiasm in math class, we should start from the following aspects: 1. To improve the enthusiasm of learning mathematics, we must strive to cultivate students' interest in learning mathematics. (1) Pay attention to the introduction of new courses; (2) We should gradually infiltrate all kinds of mathematical ideas in new courses or review classes, instead of just mastering the exercises in books. "It is better to teach people to fish than to teach people to fish"; (3) Pay attention to the combination of speaking and practicing in class. Students have limited attention and can't concentrate for 45 minutes. If the teacher talks too much, no matter how well he speaks, students will inevitably be distracted. After part of the content is finished, students can complete the corresponding exercises, which not only changes the form of classroom content but also consolidates the content of new lessons, so that students can experience the joy of success and thus improve their interest in learning. 2. Teachers should care about students and strengthen communication with them. Students' rebellious psychology may be counterproductive, so they hate mathematics, let alone enthusiasm. Students will be happy to learn only if they don't feel pressure and love the teachers they teach. Teachers should first put down their airs, communicate with students more, not scold them easily, make friends with students and care about them in life and study, thus arousing their love for teachers and mathematics; Secondly, teaching should be equal, teaching should be oriented to all, and some people should not be partial, but students with learning difficulties should be indifferent; Finally, we should always praise and encourage students, especially those with poor learning, so that they can change from being afraid of mathematics to loving it.
