Under the background of the new curriculum reform, the primary school mathematics classroom is no longer a closed knowledge training camp, nor a simple knowledge transfer. It requires classroom teaching to establish a modern educational concept of "people-oriented" and "student development-oriented". According to my own practice, the author summarizes several views.
Classroom is the cradle of students' learning knowledge, which occupies most of their learning time. The formulation of the new mathematics curriculum reform emphasizes the change from taking knowledge as the primary goal of mathematics education to first paying attention to the cultivation of people's emotions, attitudes, values and general abilities, and at the same time enabling students to acquire the basic mathematics knowledge and skills necessary for adapting to modern life as citizens. It can be said that promoting students' lifelong sustainable development is the basic starting point of school mathematics education. Therefore, what kind of strategies are adopted to guide and carry out classroom teaching plays a vital role in the embodiment of teaching value and the direction of students' growth.
1 Stimulate students' interest
Einstein said, "Interest is the best teacher." Only when students have a strong interest in what they have learned will they actively participate in classroom learning, give full play to their intelligence and get twice the result with half the effort. What measures should be taken to stimulate students' interest in primary school mathematics classroom? First of all, skillfully set the lead-in language to stimulate interest. Before class, teachers should design guidance words that can arouse students' interest in learning, stimulate students' thinking and exploration, activate students' learning motivation and ignite students' thinking sparks according to the teaching content and teaching materials. Secondly, design a challenge circle to make it interesting. Pupils have a strong desire to express themselves, love to be competitive and like to be praised. In primary school mathematics classroom teaching, if teachers can grasp the age characteristics of primary school students and consciously design competition questions and forms, students will be full of interest, enthusiasm and active learning as never before. For example, the basic knowledge of mathematics or oral answers are designed as competitions, the questions with moderate difficulty are designed as time-limited competitions, and the questions with greater difficulty are designed as decimal Olympic competitions, so that students can stimulate their interest, promote their learning and improve their efficiency through competitions. In short, in primary school mathematics classroom teaching, teachers should choose scientific and flexible teaching methods according to the content of textbooks and the age characteristics of students, and constantly innovate interesting methods to make mathematics classes interesting and climax again and again; Will let students play in school, play in middle school, learn interesting, learn happily, learn easily, learn actively and learn deeply
2. Flexible use of teaching materials
Textbooks are an important carrier to implement the syllabus and realize the teaching plan, and also an important basis for teachers to carry out classroom teaching. As a primary school math teacher, being good at using textbooks is an important guarantee to improve the teaching level and quality. First, understand the editor's intention and improve the ability to control. Whether the editor's intention can be understood is an important sign to measure the teacher's understanding of the content of the textbook. Before teaching, teachers should start with the whole primary school mathematics textbook, read through the textbook and its supporting teaching reference books, fully understand the writing intention of the primary school mathematics textbook, and find out the position and role of each part of the textbook in the whole primary school mathematics textbook system. Second, according to the teaching practice, adjust the content appropriately. In short, in primary school mathematics teaching, teachers should not only respect the teaching materials, but also pay attention to the unreasonable factors in the process of primary school mathematics teaching reform, select, supplement or adjust the teaching materials, and carry out teaching reprocessing, so as to truly achieve the goal of optimizing teaching.
3 to cultivate students' innovative consciousness
Cultivating students' innovative consciousness is not only related to the teaching quality of mathematics, but also to the talent quality of a nation and a country. Then, in primary school mathematics teaching, how to cultivate students into new century talents with solid scientific and cultural knowledge and innovative exploration consciousness has become a problem worthy of our mathematics educators' in-depth thinking. First, establish innovative consciousness and pay attention to innovative training. As the main position of teachers' teaching and students' learning, classroom teaching is the main channel to cultivate students' innovative consciousness. However, in the past teaching, most teachers neglected the cultivation of all kinds of qualities other than knowledge and skills, especially the students' innovation, exploration consciousness and creative spirit, which resulted in the bad consequences of students' "high scores and low abilities", and they were just learning machines and could not be used in practice. Therefore, teachers should not only pay attention to the implementation of basic knowledge and skills, but also tap the intellectual factors of teaching materials and students' quality and ability, and pay attention to the cultivation of creative thinking and innovation ability. Ask students why, whether the result is unique, whether they can find new methods and means, and whether there is a simpler, faster and more convenient method. Second, give full play to students' main role and stimulate innovation. Modern educational theory advocates "paying attention to students' development". In mathematics teaching, to really awaken students' subjective consciousness, teachers should transfer teaching to students' learning, give full play to students' subjective role, and let students actively participate in the process of knowledge acquisition. Only when students take the initiative to learn can teaching be implemented and innovative thinking be developed. Third, encourage questioning and cultivate innovative thinking. Mathematics is the gymnastics of thinking. Mathematics classroom teaching must focus on cultivating students' ability, especially the ability to find problems, question boldly, think independently and express creative ideas. In the teaching process, students should be encouraged to question and ask difficult questions, and their initiative and innovation ability should be stimulated.
4. Guide students to actively participate in the learning process and pay attention to the effectiveness of group cooperation.
Cultivate students' sense of cooperation: As the organizer, guide and collaborator of classroom teaching, teachers should guide students to learn to cooperate in a timely manner through certain methods, so that they can realize that a group is an independent group and every group member is a member of this group. The healthy growth of the group needs the efforts of each member, and also needs the mutual help, support, cooperation and promotion among the members of the group. The little progress of the group is the result of the joint efforts of the group members and the honor enjoyed by everyone. In this way, students' team spirit will be gradually cultivated and strengthened. Methods of teaching students to cooperate: Teachers must make it clear that cooperation ability is not innate, and like other skills, it is inseparable from conscious and planned training and practice the day after tomorrow.
5 Make full use of multimedia
Multimedia has created a lively learning scene with pictures and pictures, vivid colors and a combination of static and dynamic, which provides advanced means and methods for teaching and makes teaching more dynamic. In this environment, students can have a positive psychological experience and quickly turn it into a desire for knowledge. The use of multimedia teaching can mobilize students' multi-sensory participation in learning, help students overcome cognitive obstacles in learning, speed up learning progress and improve learning efficiency. The application of multimedia in primary school mathematics classroom teaching is more expressive and appealing than traditional teaching methods, which can change abstraction into concrete, static into dynamic, complex into simple and boring into interesting in the process of students' knowledge construction. Once the knowledge is understood and mastered by students, the visual, concrete and perceptual information will gradually deepen into abstract, conceptual and rational concentrated information. The application of multimedia teaching can stimulate students' interest in learning, provide students with powerful cognitive tools, effectively break through the key and difficult points of teaching, develop students' intelligence, cultivate students' ability and effectively improve teaching efficiency.
In short, in the teaching process, according to the psychological characteristics and cognitive laws of primary school students and the characteristics of primary school mathematics, we should take various effective forms to create appropriate teaching situations, fully stimulate students' interest in learning, and strive to mobilize students' enthusiasm for learning, so that students' mathematics quality can be fully and effectively developed in a harmonious, democratic, happy and equal classroom atmosphere.
