What problems should be paid attention to in classroom teaching of new mathematics curriculum?

The core issue of compulsory education reform is to implement quality education and the spirit of the Outline of Education Reform and Development in China. The compulsory full-time junior high school mathematics syllabus also clearly points out: "It is very necessary for students to receive necessary mathematics education and have certain mathematics literacy to improve the quality of the whole nation and lay the foundation for cultivating socialist construction talents." The practice of quality education proves that the fundamental way to implement quality education lies in classroom teaching and subject education. The premise is that teachers should change the traditional concept of education and teaching and establish a brand-new concept of education and teaching. In mathematics education, teachers are required to fully grasp the curriculum characteristics of the new mathematics curriculum in classroom teaching and fully implement the modern educational concept. First, the characteristics of classroom teaching of new mathematics curriculum 1. Basic. In the process of human development, there are a series of physiological, psychological and social stable development. The classroom teaching of new mathematics curriculum should pay attention to the natural quality of learners, mobilize their active participation and promote their vivid development. As a basic natural subject, the fundamental purpose of junior high school mathematics teaching is to cultivate and develop students' most basic quality. 2. Orderly. The implementation of quality education in mathematics classroom is a rhythmic and focused process in specific methods, rather than grasping the beard and eyebrows. According to the teaching practice, mathematics teachers should determine a problem and make key breakthroughs in each stage (school year, semester, school year month or week). The goal of quality education cannot be achieved overnight, but it must be an orderly process of long-term training. 3. comprehensiveness. Without comprehensiveness, it is not a real quality education. "two-pronged approach"-comprehensively implementing the party's educational policy and improving the quality of education is the basic connotation of quality education. In mathematics teaching, we should face all employees and promote the development of all students, not "eugenic education" and "competition education". 4. continuity. The implementation of the new mathematics curriculum can't cut off the history, can't think that all the past practices are "exam-oriented education", can't completely deny the past education and teaching activities, and can't put the effective methods and experiences that have been adopted in the past in a place that conforms to the educational laws and students' understanding. Concentric curriculum education is opposed. In the class of "exam-oriented education", quality education can also be carried out; In the classroom of the new mathematics curriculum. You should also use the test-taking method. 5. openness. Abstraction and preciseness are important characteristics of mathematics. In classroom teaching, we should not only pay attention to systematic subject learning, but also pay attention to life education and social service, so that students can have a preliminary sense of using mathematics. Second, the content of classroom teaching of new mathematics curriculum 1. Ideological and moral education. Ideological morality includes politics, ideology, morality, consciousness, ideas and so on. There are a large number of moral education textbooks in junior high school mathematics textbooks. As long as we are good at digging and making full use of them, it will play a very important role in cultivating students' scientific attitude of seeking truth from facts, the scientific spirit of being brave in learning, and the indomitable spirit of dialectical materialism and encountering difficulties and setbacks. For example, the question and answer between Shang Gao and He recorded in China's border arithmetic book Zhou Kuai suan Jing was hotly debated for the exposition of "Gou Guang San, Gu and Xian". It predates Pythagoras' discovery by more than 600 years. Another example is pi, which is recognized by China as a geometric achievement. These achievements are the crystallization of the wisdom of the ancient working people in China. Let students know these facts, which can stimulate students' national self-confidence and national pride and form students' patriotic quality. 2. Science and culture education. As a teaching subject, middle school mathematics is significantly different from abstract mathematics as a science in nature and content. This is because the focus of mathematics as a teaching subject is to complete the tasks stipulated by the teaching purpose of middle school mathematics. Specifically, he said, it is through mathematics classroom teaching that students can master concepts, cultivate skills and develop abilities. Mathematics curriculum standards require students to know, understand, master and apply mathematics knowledge, which is the task of our mathematics classroom teaching and the most basic part of students' intellectual education quality. On the other hand, students can master mathematical ideas (letter algebra, equations, combination of numbers and shapes, transformation, statistics, etc. ) and mathematical methods at the same time to master mathematical knowledge. At the same time, students' logical thinking ability (memory, transfer, divergence, analysis, synthesis, abstraction and generalization) is cultivated, so that students can have correct and rapid operation ability and gradually form skills and techniques. Scientific and cultural quality is the most important and core quality among all the qualities of students, and the important way to cultivate this quality lies in classroom teaching, so we math teachers are required to take the classroom as the center, carefully design and carefully teach. Take "teaching optimization" as the highest realm of teaching. It should be the goal pursued by our majority of math teachers. In classroom teaching, we should do "intensive teaching and intensive evaluation", try our best to make every student learn knowledge and effectively improve students' scientific and cultural quality. 3. Skill operation element education. As we all know, the obvious difference between the nine-year compulsory junior high school mathematics textbooks and the past unified textbooks lies in the addition of "exercise homework" in the junior high school mathematics textbooks, with the aim of requiring students to practice and apply what they have learned. After learning the chapter "Solving Right Triangle", students are required to make an inclinometer to measure the elevation angle (depression angle) of the object, so as to calculate the height of the object. However, this kind of homework has been ignored by many teachers. As we all know, it plays a very important role in cultivating students' practical ability and ability to apply what they have learned. It can help students solve many problems in daily life and production, and more importantly, it can improve students' skills and operational quality and develop their abilities. 4. Aesthetic education. Aesthetic education factors in junior high school mathematics textbooks can also be seen everywhere. One is the beauty of mathematical figures, such as circles and regular polygons. The other is the beauty of mathematical formulas, such as Yang Hui triangle, and the other is the beauty of mathematical problems. As carriers of beauty, these mathematical figures, mathematical formulas and mathematical problems also play an important role in cultivating students' aesthetic ability and creating beauty. On the other hand, math teachers themselves should become beautiful models. Teachers came into the classroom with smiling faces, natural and unrestrained manners, glib mouth and beautiful calligraphy. Beautiful and neat blackboard writing, intonation and the wonderful use of audio-visual education all constitute the harmonious beauty of classroom teaching. 5. Psychological quality education. In mathematics classroom teaching, we should take cultivating students' good psychological quality as an important content. Winners are not proud, losers are not discouraged, answering questions in class is not nervous, exams are not afraid of stage fright, and problems are not discouraged. This should also be an important part of our mathematics teacher's teaching. Third, the classroom teaching principle of the new mathematics curriculum 1, really put students' dominant position in the first place and create a good and harmonious learning atmosphere. The disadvantage of traditional teaching is that it greatly limits students' initiative and stifles their interest in learning. In fact, teaching activities are bilateral activities between teachers and students, and the process of mathematics teaching is not only a cognitive process, but also an emotional communication process. In teaching activities, we should pay attention to the age characteristics and cognitive rules of junior high school students, and be good at stimulating students' emotions in learning mathematics. Because of the age characteristics of junior high school students, there are both lively and curious characteristics of primary school students and eager to mature. Therefore, we should be good at grasping the positive factors, encouraging the suspicion and exploration of the China Learning Alliance, so as to make students' whole learning activities full of joy and realize their learning needs. In the whole teaching process, we should always embody the teaching principle of "students as the main body and teachers as the leading factor", give students full autonomy and create a good and harmonious learning atmosphere. 2. Rational layout of classroom structure and optimization of mathematics teaching methods. In classroom teaching activities, teachers should accurately grasp the teaching objectives, objectives, key points, difficulties and other teaching contents, and at the same time grasp the time very strictly to avoid blindness and randomness in teaching. In terms of quality, teachers should concentrate; In terms of content, students are determined not to speak easily. In the whole teaching activity, teachers should not only pay attention to the systematic transmission of knowledge, but also give students opportunities to think, speak and practice. 3. Strengthen the excavation of non-intelligence factors (motivation, interest, emotion, will, personality, etc.). ) Cultivate students' good mathematical literacy. Practice has proved that the important reason for students' polarization is the difference in the development of non-intellectual factors. In learning, many students have other major obstacles besides their own intellectual factors, such as poor learning, lack of interest, difficulties, inability to face difficulties, lack of courage to overcome difficulties and so on. Therefore, in mathematics teaching, we should cultivate non-intellectual quality from four aspects: cultivating interest, stimulating motivation, establishing emotion and strengthening will.
