The biggest feature of the textbook published by Beijing Normal University is the appearance of every mathematical knowledge, and the solution of every mathematical knowledge is closely related to real life. We study because of the needs of real life, and use the mathematical knowledge we have learned to solve problems in life, which fully embodies the new curriculum standards of "mathematics should be attached to life" and "mathematical problems should be integrated into life". In fact, students are more interested in mathematics knowledge with a certain life foundation. This requires that the situation set by our math teacher should be linked with the reality of students' lives and pay attention to practical results. We can make use of the characteristics of rich information resources and strong timeliness to organically integrate information technology with primary school mathematics teaching content, make full use of various information resources, introduce the living water of the times, and combine with mathematics teaching content to make students' learning content more colorful, more contemporary and closer to life and modern science and technology; At the same time, it can also broaden teachers' knowledge horizons, change the traditional subject teaching content, make teaching materials "live" and make mathematics learning closer to life.
For example, in the practice class of teaching schedule, I created such a life situation: a school organizes an autumn outing, and the destination of the tour can be any of the following three cities: Hangzhou, Suzhou and Shanghai. Teachers show pictures of three cities with the help of network resources, so that students can know their positions and tourist attractions. Then organize students to discuss the issues to be considered in this trip, such as: where to go, how to go, how many days to travel, how much to spend, etc. On the basis of clarifying the problems that need to be solved in this activity, students choose ideal tourist destinations and various ways of playing in groups, and briefly sort out the whole activity plan and results. Then let the group search for the required information on the internet in the form of division of labor according to their own choices. Then use data to solve related problems. Like calculating money? Selection of the best route, etc. In the communication, many different views were displayed. Some people think that a short trip to Hangzhou is relatively cheap. Some people think Suzhou is cheap, and they can also enjoy the beautiful scenery of the Beijing-Hangzhou Grand Canal by boat. The diversified research of students in a given situation makes teaching and learning very creative and full of vitality.
2. The integration of information technology and primary school mathematics teaching forms-reappearing the process of knowledge formation.
The images displayed by information technology can produce dynamic beauty; It can stimulate students' curiosity, explore the mystery of knowledge, guide students' unintentional attention to intentional attention, and effectively improve the frequency of information feedback. The image transformation process of information technology display is also the true beauty and scientific beauty of revealing the inherent law of mathematical knowledge. It helps students to relieve audio-visual fatigue, maintain vigorous energy and improve learning efficiency.
For example, when teaching the understanding of cylinder, after careful analysis of the teaching materials, it is found that the difficulty of this lesson is: how to understand that the side expansion diagram of cylinder is a rectangle. Therefore, by making teaching courseware, the side unfolding process of cylinder is demonstrated by computer animation. After watching the animation, students can easily form the whole process of cylindrical edge development in their brains. They clearly realized that the side development of the cylinder is a rectangle, and correctly stated the relationship between the length and width of the rectangle and the circumference and height of the bottom of the cylinder. It solves the difficulties of this course and improves the efficiency of classroom teaching. Practice shows that it can also provide students with rich perceptual materials that are not limited by time and space, which is conducive to strengthening students' participation in various senses and enriching students' thinking and association. Therefore, the effective use of information technology is like inserting a pair of powerful wings into students' thinking, so that students' innovative thinking can fly freely in the classroom. This is what students dream of and what our teachers pursue.
Third, the integration of information technology and primary school mathematics teaching methods-the classroom can be so wonderful.
In the traditional teaching mode, students passively accept knowledge under the guidance of teachers, and lack the time and space for autonomous learning and cooperative learning, and the opportunity to acquire knowledge independently. With the participation of modern technology, students' learning needs at different stages are met, and they are not limited by teachers, nor can they not carry out learning activities because there is no teacher. Students' study is open and free. Communication in the learning process is more extensive.
(1). Under the network environment, guide students to explore independently.
The new curriculum standard advocates students' autonomous learning, which increases the teaching capacity and broadens students' knowledge. Acquire knowledge through independent thinking and dialogue. It has cultivated their ability to acquire knowledge, analyze and solve problems, and also cultivated their independent spirit and cooperative quality. Online learning is rich in content and diverse in learning forms. Students learn what they want to learn according to their hobbies. It meets the needs of students and greatly stimulates their interest in learning. Such as; When encountering difficulties, students can raise their hands to ask questions to teachers electronically or use online classrooms or chat rooms. Students break the space limitation, have a "logical" group discussion, and realize the optimization of classroom exercises. Multi-directional communication network learning mode breaks through the constraints of textbooks, meets the needs of students' personality development, develops students' thinking in the process of reciprocating exploration and autonomous learning, and ignites the spark of innovation. Let students learn many things that books can't learn and broaden their knowledge.
(B) train students to study online under the network environment.
"Online learning" learning mode is widely used in review classes, and its advantage lies in the realization of personalized learning, which can "take what you need" and "take what you need". It integrates knowledge review, problem-solving guidance and self-examination into a courseware, and students allocate time to study by calling out the contents recorded and stored in the courseware according to their own learning situation, which is more conducive to the mastery and application of knowledge. For example: knowledge review. According to the main points of this unit, students can form the reproduction of knowledge through individual learning. For the difficult problems in mastering specific knowledge, they can provide relevant paths for visiting and learning through hyperlinks. Practice stage. Design gradient exercises with different difficulty levels to meet the needs of different students, and realize personalized learning by human-computer interaction; Discussion area. If students encounter difficulties, they can enter the discussion area to realize student-student communication or teacher-student communication, get help from teachers and classmates, and cultivate students' communication ability and emotional quality. Self-detection stage. Used to check the knowledge of this unit. After completing the questions, students can submit answers, not only to check their grades in time, but also to know which questions are wrong. There are some ways of testing, such as testing, star rating test, game mode, etc., to try to stimulate learners' enthusiasm for challenges, encourage curiosity and creativity, and let the happiness of hard work and success dilute the boring and hard work of learning. Here, teachers are no longer the main providers of information and the leaders of learning, but will become the guides and supporters of students' personalized learning exploration activities.
There are many ways and methods to integrate information technology with primary school mathematics, which greatly improves the effect of mathematics classroom teaching and is welcomed by students. It is incomparable with traditional educational technology. With the continuous development of information technology, the integration of information technology and primary school mathematics curriculum is undoubtedly the requirement of the information age, and it will certainly become the main method of school education and teaching in the 2 1 century. Therefore, we should give full play to the advantages of information technology, provide a colorful educational environment and powerful learning tools for students' learning and development, and effectively cultivate more cross-century innovative talents.
