The development of modern information technology has brought a new atmosphere to our classroom teaching reform. In particular, the wide application of multimedia in classroom teaching is quietly changing the teaching concept and teaching method of each teacher. Realize the deep integration of information technology and mathematics teaching, give full play to the advantages of information technology, change the presentation of teaching content, provide students with a rich and varied learning and development environment, and enable students to devote their interest to realistic and exploratory mathematics activities. Going in is the pursuit of every teacher. How to implement the education concept of the new curriculum into the classroom teaching and use multimedia technology to optimize the teaching content? In this article, I will talk about my own attempts in this aspect in combination with my own teaching practice. First, add "love" plus "interest" In the world of children's learning, the feeling of happiness is the emotional basis of learning. In the classroom, we found that when students like an activity, they will fully devote themselves to achieving high efficiency and ideal results. In classroom teaching, we should create a happy learning environment for students, stimulate students' interest in learning, and promote students' interest in learning with interest. Multimedia technology can give play to the advantages of shape, sound and color, and contribute to the student's music. For example, when a teacher is teaching the concept of graphic perimeter, he designed the plot of "Turtle and Hare Racing". The tortoise ran around the circular grass, and the little white rabbit ran around the rectangular grass. The lively scene caught the students' hearts and grasped the meaning of the "circumference" with the vivid scene. Another example is that after learning the multiplication of 9, I designed a "flower blossoming" exercise. In the garden full of colorful flowers, each flower bud has a multiplication method, which is designed as a trigger for each flower. Students can choose their own questions, and the flowers will be open. This will increase the fun of student practice. Appetite is a glue for classroom teaching. It makes full use of multimedia in primary school mathematics to create the characteristics of easy and interesting learning scenarios, adding “love†and “interest†to the classroom. Second, avoid "virtual" and "real" Nowadays, the textbooks we use incorporate rich elements of life into the teaching content, but after all, it is limited by the region and customs. The content in the textbook sometimes has a greater distance from the students' life. For example, in the Qingdao version of the math textbook, a large amount of content is based on the seaside life, which is far from the environment of our Weifang. It is somewhat reluctant to let the six or seven-year-old Weifang children learn from the textbooks only through the study of textbooks. What should I do? I have listened to the lectures of several teachers and made bold revisions to the contents of the textbooks. The familiar scenes such as Weifang Kite and Jinbao Paradise are displayed in the classroom through multimedia courseware, and are included in the classroom learning resources. in. These familiar materials have greatly mobilized the students' existing life experiences, and the understanding of "Mathematics comes from life and life" is a matter of course. The content of mathematics learning should be realistic and meaningful. In the teaching, combined with the actual life of the students, the current teaching materials are effectively selected, adapted, combined, and presented to the students with a brand new look. With its large capacity and intuitive image, multimedia technology provides technical support for the reorganization of teaching content. In the click of the mouse and the conversion of the screen, "Let them realize that mathematics is around, feel the fun and application of mathematics, and have a sense of intimacy in mathematics." Third, go to "rough" to take "fine" “Creating a situation, let students learn mathematics in vivid and specific situationsâ€, under the guidance of this educational concept, the use of information windows in the textbooks in mathematics teaching to create an open learning atmosphere for students. Students explore mathematics problems on the basis of independent and independent analysis, find ways to solve problems, and cultivate the flexibility of students' thinking. In the teaching practice, I found that the learning situation created by the textbook information map, although the background content is based on the activities of children's interest, but presented in front of the students in a static way, the mathematical information in the information window is presented to the students. It is a single one that requires the collection and organization of students to make it a valuable mathematical problem. In teaching, I use modern information technology to carry out secondary processing of information maps, to "rough" and "fine", to highlight relevant information, enhance students' cognition, and help students understand in reinforcement. For example, when teaching 7 multiplication, in order to guide students to independently write 7 multiplications, I intercepted the scenes of 7 students in the information window, and highlighted them from the information window, effectively concentrating the students' attention. . Fourth, change "quiet" to "moving" Multimedia courseware can dynamically simulate the changing process of things, playing a role that traditional teaching can't match. Changing "quiet" to "moving" is one of its great advantages. Through "moving", the subject of the courseware is more vivid, more attractive and appealing. At the same time, the dynamic demonstration of multimedia courseware can eliminate many misunderstandings in human demonstrations. In the teaching of graphic graphics, the superiority of multimedia can be more reflected. When we have knowledge of the area of ​​the teaching circle and the surface area of ​​the cylinder, we all have this experience. After a period of teaching, the students will fall into ambiguity about how to calculate. Why? The reason is that students lack a deep and intuitive understanding of the origin of the area calculation method. As Hua Luogeng said: “The number is invisible and less intuitive, and it is innumerable and incomprehensible.†In the teaching of graphic knowledge, most of the teachers use multimedia animation after the students independently explore, using the image's flicker, rotation, movement and color, Changes in sounds, etc., reproduce the formation process of knowledge points, and deepen the students' perception of the knowledge points. Using multimedia to optimize teaching content and realize the deep integration of information technology and mathematics requires us to constantly think and explore in practice. As long as each of our teachers integrates our educational wisdom into our teaching practice, we will be able to create a spring of multimedia teaching.
