As a contemporary mathematics teacher, if you can be familiar with the theory and operation skills of multimedia teaching methods, and can reasonably use information technology to assist mathematics teaching according to teaching standards. Its basic starting point is to promote students' all-round, sustained and harmonious development. We should not only consider the characteristics of teaching itself, but also follow students' psychological laws in learning mathematics, emphasizing that starting from students' existing life experience, students should experience the process of mathematics learning personally, abstract practical problems, and make progress and development together with students' values. Furthermore, the application in primary school mathematics classroom should proceed from students' reality, reasonably select modern teaching media, and combine with traditional teaching media and conventional teaching methods, which can greatly enrich classroom teaching, promote students' understanding, mastery and migration of knowledge, cultivate students' various abilities, improve students' quality, greatly improve teaching efficiency and give full play to the advantages of information technology.
1. Advantages of information technology in primary school mathematics classroom teaching
Information technology has been put into practice in primary school mathematics classroom teaching, and has shown many advantages. To sum up, it mainly includes: ① Pictures, words, sounds and images to mobilize students' emotions, emotions, attention and interest from multiple angles. (2) Intuition can break through the limitation of vision, observe objects from multiple angles, highlight key points, and help to understand some teaching concepts and methods. ③ Changing static state into dynamic state, embodying concepts and processes, can effectively break through difficulties. (4) More interaction, more students' participation, more active learning, and help students form a cognitive structure through the real environment. ⑤ Cultivate students' exploration and creativity through the reproduction and simulation of real scenes of information technology. ⑥ Repeatability of teaching process is conducive to breaking through difficulties and overcoming forgetting. ⑦ Strong pertinence makes it possible to teach at different levels. ⑧ A large amount of information saves space and time and improves teaching efficiency. Pet-name ruby make some abstract and difficult concepts into concrete and considerable pictures, that is, abstract into concrete. Taking part in the application of information technology in primary school mathematics classroom, teachers have changed their roles from traditional managers and interpreters to technical assistants, collaborators and helpers. Students' thinking process focuses more on mobilizing various cognitive strategies to solve practical problems. So as to learn "how to learn and how to think".
The application of information technology in primary school mathematics classroom has indeed provided good conditions for students' learning and teachers' teaching, and received good results, which has become the consensus of people.
2. Thinking about the application of information technology in teaching.
Everything has its positive and negative effects, and the application of information technology is no exception. When we see the advantages of information technology applied in primary school mathematics classroom, we should also see the side of information technology going astray in education and teaching. Therefore, we must find the misunderstanding in time, analyze the misunderstanding and get out of it.
2. 1 Multimedia teaching can't ignore the cooperation process of students; Cooperative learning refers to a teaching method in which students engage in learning activities in group learning with different abilities. With the rapid development of science and technology and the arrival of the information society, the future society will pay more and more attention to whether individuals can cooperate with others, effectively express their views and opinions, listen carefully to others' opinions, summarize and absorb others' opinions, etc. Therefore, it is becoming more and more important to cultivate the spirit of group cooperation to promote the unity, coordination and gregarious among primary school students, so multimedia programs should be designed for students. The study of situational learning shows that learning is a socialized process, and the cooperation between students has obvious effects. Therefore, in interactive teaching, some processes and contents should be designed for students to discuss and solve cooperatively, so as to improve teaching efficiency. It is necessary to use information technology to create learning scenarios, divide students into groups, discuss problems together, find problems and debate them. All these can ensure that students have the opportunity to make clear statements and "turn silent knowledge into clearly expressed knowledge", thus promoting students to help each other in their studies.
2.2 sublating multimedia should make the finishing point; The more information technology is used, the better, but it should be just right. It is also necessary to give children more opportunities to start work and give children room for imagination, which is also a space for creation and exploration. Information technology has many advantages, but improper use can also have side effects. If you want to do a good job, you must first be familiar with the tools and understand their characteristics, so as to maximize their benefits. Some teachers, after tasting the sweetness of multimedia, use multimedia in some classes from beginning to end, ignoring the role of other conventional media. Some teachers even use multimedia instead of blackboards and wall charts. Modern educational psychology has proved that in the teaching process, teaching methods and skills that embody personal style can make teaching lively and distinctive. To prevent teaching ideas from being dominated by multimedia, our good teaching style will be lost by computer demonstration programs and eventually lose the advantages of multimedia teaching. For example, write the teaching ideas of a class on the blackboard in order, and students can have a look and think after class, which will better help students understand and remember the content of the class. Although information technology has incomparable advantages over other media, some special functions of other traditional media can not be ignored. For example, projection, the static display function of slide show and the function of enlarging the real scene, the spatial structure function of teaching model and so on. , all have their good teaching functions, and some can't even be completely replaced by computers. Therefore, teachers should choose appropriate teaching methods and means according to teaching needs, organically combine information technology with other conventional media, and optimize classroom teaching.
2.3 The application of information technology can not ignore the cultivation of students' operational ability; We should not neglect the cultivation of students' practical operation ability because of the intervention of computer-aided teaching. For example, learning mathematics through practical operation is the characteristic of primary school mathematics teaching, and it is also determined by the age characteristics and thinking of primary school students. When teaching weight units, we should pay attention to let students use them correctly. Students don't have to weigh a kilogram by hand. How do they feel the weight of heavier objects? When teaching geometric figures such as length, cube and angle, let students touch and feel the objects and angles of cuboids and cubes. On the basis of hands-on practice, use the advantages of computers to help students form concepts. This kind of teaching conforms to the cognitive law from concrete to abstract, from perceptual to rational and the psychological characteristics of primary school students.
