Mr. Dewey, an American educator, once said, "What kind of education you give your children is what kind of life you give them!" What kind of math class should be given to children under the concept of new curriculum reform? What kind of emotional experience do you give your child? After several years of teaching attempts, I think a math class is a good one if it can stimulate students' interest in learning math and acquire math skills through repeated training. First of all, the class is a happy place. Mathematics teaching is a process of emotional flow between teachers and students. Positive emotions can stimulate students' interest in learning, improve teaching efficiency and help to form good quality. At the beginning of class one math class five, the class teacher took more than ten days off, which really made me feel that there are no tigers in the mountains, and monkeys are called bullies. I am naughty, which makes the headmaster criticize me every day. I reason with them in math class almost every day, and then I start my class angrily. I haven't laughed once, and I want to cry every day. As a result, the psychological distance between me and my students is getting farther and farther. The first monthly exam was terrible. This sentence made me think deeply Yes, if every minute a child spends in class is painful, how can a child love learning? Since then, I have been smiling in every class. According to the established teaching design, I stipulate that in each math class, I should make students laugh at least three times, applaud them sincerely once, and complete all the learning tasks with laughter, so that students can be relaxed and active and speak freely. Second, the classroom is the stage for dialogue. "The classroom should not be a monologue, but a communication between two subjects, a free, open and personalized dialogue between teachers and students, between students and between teachers and students and texts." We should strive to achieve "the collision of thoughts, the blending of emotions, and the acceptance of the soul." In the classroom, students need to form their own overall perception and grasp of what they have learned through full understanding, calm thinking and heated discussion, and profound understanding and understanding will also produce various doubts, which require communication between students and teachers and students, so as to make students' understanding more perfect and satisfy their desire to express, thus stimulating students' interest in learning mathematics, expressing their thoughts freely and forming their abilities. Third, the classroom is the starting point of innovation. For a student, as long as his "activity" is unprecedented for him personally and valuable for individual development, it can be regarded as innovation. To cultivate students' innovative consciousness, it is necessary to protect students' psychology of finding problems and actively exploring, let students express their opinions freely in class, let students feel successful through different forms of rewards such as small red flowers, and promote the rewarded to work hard in the direction of rewards. In short, as long as students actively participate, actively communicate, form skills, really mobilize their subjective initiative, and promote the bilateral activities of teaching and learning, this is a good math class.
