Create life situations and guide students to actively participate in learning. Mathematics comes from life, and mathematics knowledge cannot be separated from life. Guide students to find mathematical problems in life cases, explore mathematical laws, make them realize that mathematics is closely related to life, and deeply feel the fun and value of learning mathematics, so that students will take the initiative to learn, thus loving mathematics and willing to learn mathematics. 1, make full use of life materials, pay attention to life practice, and stimulate students' interest in learning. Being good at discovering mathematical problems in life and making full use of mathematical materials in life for teaching make students feel natural, friendly and easy to understand, which not only stimulates students' interest in learning, but also promotes their understanding of new knowledge. Mathematical knowledge can not be separated from life, and mathematical activities can not be separated from life. The process of mathematical practice is the process of combining mathematics with real life, and it is also an effective way to cultivate and improve students' practical ability. Therefore, in the teaching process, we should create a more practical practice environment for students, let them find problems in life practice, further broaden the knowledge learned in class, and create conditions for the development of students' thinking ability and personality. When doing math exercises, we can introduce some related life problems, apply what we have learned and apply what we have learned to cultivate students' math consciousness and ability. 2. Carefully create life scenes, let students experience the value of mathematics, and encourage students to take the initiative to learn. Excavate the life scenes in mathematics content, make mathematics close to life, let students get positive emotional experience in observation, operation and communication, truly realize that life is full of mathematics, and feel the true meaning and value of mathematics. Guide students to apply what they have learned, apply what they have learned, serve their own lives, and let students feel the value of learning and mastering knowledge. In the process of analyzing and solving problems with what they have learned, cultivate their awareness of applying mathematics and their ability to comprehensively apply what they have learned to solve problems. Mathematical knowledge is widely used in real life. Only by letting students really use mathematical methods to solve practical problems in life and realize the close combination of mathematics and life can students learn to live and improve their practical ability in life. 3. In teaching, students should be guided to learn to learn and create. The famous scientist Descartes once said: "The most valuable knowledge is the knowledge about methods." Mr. Ye Shengtao, a famous educator in China, advocates cultivating students' ability to think and solve problems independently, and puts forward that "teaching is to achieve the purpose of not needing teaching." Therefore, modern mathematics teaching should not teach students ready-made mathematical knowledge, but should teach students learning methods. In other words, the important task of teaching is to let students learn to learn. As a math teacher, we should not only guide students to solve the subject learning content in textbooks, but also actively design some problems related to reality for students to solve, and even mobilize students to collect some real math problems and bring them to class to learn, so as to take a road of returning mathematics to reality and developing mathematics in practical application. In this way, students constantly find math problems confusing in practical application and are eager to solve them. Through peer help and communication between teachers and students, we can solve problems and experience the endless fun of learning math topics. 4. Prompt the anecdotes of people hidden behind the mathematical knowledge. Theorems, principles, rules and formulas in mathematical knowledge give people a "boring feeling", but there are little-known moving stories behind these knowledge. Introduce students to the history of mathematics, short stories of mathematics, interesting stories of mathematics, stories of mathematicians' growth, etc. Linking mathematical knowledge with creative activities with human flesh and blood will make students feel intimate with mathematical content. Curiosity can make people have a strong interest in something and a phenomenon, and then actively think, explore and study hard. Everyone is curious, especially the students who are in the stage of seeking knowledge. Fourth, explore the beauty of mathematics and let students experience happiness in scientific inquiry. The beauty of mathematics is "the beauty of coldness and seriousness", which needs teachers' constant guidance to let students experience rationally. Once students have the ability to feel the beauty of mathematics, the resulting interest in learning mathematics will be stable and lasting. Excavate the "unified beauty" of mathematics in the unification of number system, operation and number shape; When applying mathematical methods to solve problems in other disciplines and connecting with practical problems, we should explore the "abstract beauty" of mathematics; Excavate the "rigorous beauty" of mathematics in logical reasoning, logical operation and mathematical discussion of "more than one dime is long, less than one dime is short"; Exploring the "singular beauty" of mathematics in the teaching of changeable and multi-solution problems. As long as teachers pay attention to digging, the beauty of mathematics is everywhere. As long as there is convincing guidance, students' ability to perceive the beauty of mathematics will increase day by day. Fifth, temper willpower and let students pursue happiness in overcoming difficulties. "Interest is the best teacher." Piaget said: "If a student doesn't have a chance to taste all the joys and sorrows in solving problems in school, then his mathematics education will fail in the most important place." Teachers must help students set up lofty ideals and goals in life, make them fully realize the important role of mathematics in achieving this goal, and make them understand that it is impossible to learn mathematics well without years of hard work and persistence. At the same time, create more learning scenes of "the mountains are heavy and the water is doubtful, and there is no way out", so that students can experience more unusual success and happiness after suffering. Sixth, enhance the sense of accomplishment, so that students can feel happy in continuous success. A sense of accomplishment is the motivation for a person to remain interested in an activity. Objectively speaking, in the junior high school stage of universal education, it is unrealistic to satisfy every student's sense of accomplishment with one-size-fits-all requirements. This requires teachers to apply the principle of teaching students in accordance with their aptitude, treat them in different categories, and adopt the "foot-in-the-door effect" to make students feel the happiness of success on the original basis and strengthen their interest in learning mathematics in the accumulation of success; Secondly, teachers should be really good organizers, guides and collaborators. Piaget believes that the task of math teachers is to give students appropriate help. When students truly feel that I am a master of finding, asking and solving problems, the resulting sense of accomplishment is self-evident. Let students experience the sense of success in mathematics learning. Constantly making students succeed is the fundamental way to cultivate and improve their self-confidence. Every student is eager for success. Success is a huge emotional force, which can make students have a positive psychological impact of seeking knowledge. Teachers should pay attention to students' individual activities, provide opportunities for students with different thinking levels, let them succeed, experience success, and share the joy brought by success with other students. Mathematics knowledge thinking is fierce, and students have different levels of knowledge, so it is often difficult for teachers to take care of every student in class. Establish a learning cooperation group, so that the person in charge of learning can act as the teacher's assistant, the student's learning role model and their little teacher. This not only promotes the communication between teachers and students, but also promotes the communication and cooperation between students. You can also organize a group or the whole class to answer a question or an exercise, so that boring and monotonous teaching activities can be carried out in a warm and happy atmosphere generated by the competition among students.
