(A) the strategy of building a harmonious mathematics classroom 1, in building a good relationship between teachers and students into harmony. Harmonious society is a layered harmony, the core of which is the harmony between people, that is, the harmony between people is the basis to ensure the balanced development of social organisms. Then, in mathematics classroom teaching, the relationship between teachers and students is the main body of whether this "small society" can be harmonious and whether students can develop in a balanced and individual way. Teacher-student relationship is the most basic and important interpersonal relationship in the process of education, and good teacher-student relationship is the basis of harmonious mathematics classroom teaching. Therefore, teachers have changed from "teachers" to "promoters"; Teachers have changed from "condescending" to "equal"; The relationship between teachers and students, students and students is equal and cooperative, without any discrimination or criticism. Teachers should bring smiles and encouraging applause into the classroom. Teachers should use infectious language in teaching, let students speak freely and discuss freely, and improve students' ability of cooperation, communication and inquiry. 2, relying on teaching materials to approach harmony. There are very rich emotional factors in the teaching materials of curriculum reform. From a set of data, a beautiful picture and so on, students can be infected and educated. While relying on teaching materials to engage in teaching activities, we should carry out "deep processing" of teaching materials-active selection, effective reorganization and perfect integration. For example, in the teaching research of "cuboid cognition" in the field of spatial graphics, the following teaching links are designed: L. Dialogue between teachers and students. Show chalk boxes, red bricks and other items. Students point out what shapes they are. 2. Questions and answers between teachers and students. Students give some examples of rectangular objects. 3, teachers and students * * * cooperate with the operation demonstration. Teachers and students cut radishes with knives and know faces, edges and vertices. 4. Group discussion. Characteristics of cuboids. In the above-mentioned teaching process, teaching content is presented in different ways, such as text presentation, visual demonstration, experimental operation, touch feeling, media display and so on. , so as to arouse the enthusiasm of students. Creative use of teaching materials, combined with real life, enables students to learn and use mathematics in a relaxed and pleasant atmosphere. 3. Walk into the harmony of the preset generation. With the further deepening of curriculum reform, today's classroom is showing a trend of "rigid to flexible", paying more attention to the experience of the process, paying attention to what happens immediately in the process of experience, and constantly emerging new ideas and concepts in the process of "moving". Students are agile beings, and many unexpected phenomena often appear in the rich and changeable classroom teaching situation. In the face of these generative teaching resources, how to seize and make it an opportunity for education and teaching in time requires not only teachers to conduct in-depth research on the content to be taught before education and teaching, but also presuppose the teaching value, the cognitive starting point of the educational object and the learning situation, which requires teachers to have a pair of keen eyes and conduct value guidance at any time. Therefore, in teaching, we should boldly let all students explore and trust them. The teacher's task is to open up a broad exploration space for students, carefully understand different thinking and methods, and give judgment and guidance when necessary. Never make too many restrictions or instructions in advance, let alone set any preset "traps" for their discovery, pay attention to students' independent discovery and inquiry, and stimulate the enthusiasm of the whole class to learn and use mathematics. In this way, the perfect combination of teaching and learning is realized, and the overall harmony of the teaching process is emphasized. 4. Walk into harmony in the rendering of environment and atmosphere. Bruner, an American psychologist, said: "The best motivation of students is their interest in the subjects they study." Interest is the best teacher and the most important learning booster for students. Because of its abstraction, mathematics subjects often make people feel boring, monotonous and boring, which is far less attractive than emotional subjects such as Chinese. Therefore, teachers should pay attention to creating a good learning environment and challenging atmosphere in view of the characteristics of mathematics and pupils' strong curiosity, so as to make classroom teaching full of vitality. (B) the establishment of a harmonious mathematics classroom teaching model 1, interactive classroom. (1) equal dialogue. Resolve the strict barriers between teachers and students and between students. On the one hand, teachers and students are equal. Recognize students' subjectivity in communication and interaction, give students the rights they deserve, and give students the opportunity to speak and participate actively. On the other hand, keep doing it. Teachers cannot make some students "aristocrats" and others "slaves" in classroom teaching. To achieve equality between teachers and students, teachers should learn to "condescend" and "listen"; In order to achieve life, teachers should learn self-control, eliminate prejudice against students, treat students equally in various ways, and mobilize the enthusiasm of students to participate. (2) mutual respect. There are three aspects: first, teachers respect students' true inner experiences and emotions. Teachers should put themselves in the students' shoes and pay attention to their existence and needs. For example, in the cognitive relationship, teachers can't ask students in the cognitive way of adults, and they can't ignore students' own cognitive way; In the emotional relationship, teachers can't ignore the emotional experience and emotional needs that students feel as minors; In social relations, teachers, as social spokespersons, educators and imparting knowledge, should treat students democratically and equally. Second, teachers should respect students' behavior choices on this basis. Third, we should respect students' whimsy. (3) judge each other. Mutual judgment is not to destroy, but to make others accept their own ideas, concepts, etc. , but also to let yourself get other people's ideas, reach an understanding with others, so as to develop yourself. In classroom teaching, the forms of deskmate communication, group communication and class communication are adopted, so that each student has the opportunity to show his own thinking and express his different opinions.
