In today's module study, Mr. Liu talked about the connotation of basic mathematics activity experience. Teacher Liu believes that as long as a student has experienced the activity of cutting a geometry, he will have the experience of cutting a geometry, and as long as he has done the activity of coin toss, he will have the experience of coin toss, so the experience of students participating in mathematics activities is part of the experience of mathematics activities. Curriculum Standard also points out: "Mathematics teaching activities must be based on students' cognitive development level and existing knowledge and experience. Teachers should stimulate students' enthusiasm for learning, provide students with opportunities to fully participate in teaching activities, and help them truly understand and master basic mathematical knowledge and skills, mathematical ideas and methods in the process of independent inquiry and cooperation and exchange, and gain rich experience in mathematical activities. " Therefore, in mathematics teaching, teachers should pay attention to helping students accumulate basic experience in mathematics activities. So how can our math teacher help students accumulate experience in math activities and let their thinking fly on the basis of existing experience? I can't help but think of the "Application of One Yuan Linear Equation" taught by Teacher Sun in our school class competition last year. This class answered this question well. In this class, I think Mr. Sun has done a good job in helping students accumulate experience in mathematics activities. First of all, Mr. Sun uses students' familiar life to stimulate interest, and in the way of presentation, the details are designed in place. Teacher Zheng's choice of the situation carrier of mathematics activity experience is very good. Every holiday, major shopping malls will hold promotional activities, which are familiar to these students. Teacher Sun makes full use of students' life experience in teaching, and students are familiar with it and easy to accept it. First of all, the teacher shows all kinds of promotional activities in the shopping mall on the whiteboard, so that students can understand "how to spend the most cost-effective" and lay the foundation for comparing the optimization of various consumption in the next step. Students think seriously, and active thinking is an indispensable soul in class. The introduction of buying and selling activities is more likely to stimulate students' active participation, create a relaxed and happy learning atmosphere for students, and fully mobilize their learning enthusiasm. Secondly, Teacher Sun guides students to explore new knowledge with existing experience. On the basis that students have solved the profit problem, it is very good for Mr. Sun to use the existing experience to explore solutions to more complicated problems. The graphics on the courseware will move, and students will experience and get direct experience. On the basis of students' direct experience, she also trains students to divergent thinking and accumulate mathematical experience. Teacher-led, student-centered, and teacher-student cooperation can stimulate students' interest in learning, enliven the classroom atmosphere, enable students to find problems, solve problems, and let students operate, which can not only train students' divergent thinking, accumulate mathematical experience, but also improve students' enthusiasm for learning, acquire learning methods, and guide students' thinking to develop step by step. In this way, students' enthusiasm for learning mathematics is mobilized. What Mr. Sun does best is to give students enough time to think and pay attention to the development of each student. The teacher's classroom questions are very directional, and the teacher gives the students the time completely, which shows that the students are the masters of the classroom. Give students enough time to study independently, students' thinking time is enough, students' thinking is dynamic, they are in a difficult state, they have associations based on past experience, and then use equation model to solve problems in life, so as to realize the accumulation of students' mathematics experience and make mathematics learning close to students' life experience, which is conducive to mobilizing students' learning interest, improving classroom learning efficiency, paying attention to each student's changes and fully embodying the effectiveness of teaching activities. I remember: Dewey once said that "education is the transformation or reorganization of experience." This transformation or reorganization can not only increase the meaning of experience, but also improve the ability to guide the later experience process. "An ounce of experience is worth a ton of theory. Therefore, in the future mathematics teaching, I will learn from experts and colleagues, let students participate in all aspects of mathematics learning, promote students' thinking about mathematics based on existing knowledge and experience, guide students to learn to accumulate experience in mathematics activities, and become the main body of learning. Let's join hands, pay attention to the experience of mathematics activities and build a smart classroom together; Be a teacher that children like and create a classroom that children like.
