Now is the era of knowledge explosion. In today's information age, it is absolutely impossible for teachers to have new ideas, new concepts, new knowledge and new abilities only by chalk and blackboard. However, because of its own characteristics, middle school mathematics does not have the vividness, vividness and concreteness of some subjects, and students tend to feel bored when studying, thus affecting their enthusiasm for learning. Therefore, we must learn multimedia teaching design and skillfully use multimedia courseware in teaching, not only in open classes and research classes, but also in home-made classes, so as to give full play to the role of information technology and improve classroom teaching efficiency. Therefore, teachers put pressure on themselves, learn new educational concepts, learn courseware making techniques and improve their ability to process information.
Secondly, the integration of multimedia information technology into classroom teaching helps to reduce the teaching burden of teachers.
In the process of preparing lessons, teachers need to consult a lot of relevant materials, and the huge stacks have only limited resources. Moreover, the teacher has to search page by page, turning page by page, which consumes a lot of time for the teacher. Network information provides endless teaching resources for teachers and opens up a shortcut for teachers to carry out teaching activities. Every teacher can download the information he needs in a short time as long as he enters the URL in the address bar, which greatly saves the time for teachers to prepare lessons. With the rapid development of computer software technology and the establishment of distance education network, a huge communication space has been created for educators, and a large number of practice software and computer-aided testing software have appeared, which allows students to consolidate what they have learned in practice and testing, decide the next learning direction, and realize personalized tutoring teaching. In this process, computer software has partially replaced the functions of teachers, such as setting questions and evaluating. , thus reducing the burden on teachers. Therefore, it is more and more necessary for mathematics teaching to reflect the informatization of teaching process, and multimedia information technology, which was originally used as an auxiliary tool for teaching, has gradually shown its irreplaceable role in mathematics teaching.
Thirdly, combining information technology with the subject characteristics of mathematics teaching is conducive to improving students' learning enthusiasm.
Interest is the best teacher. Good interests bring good learning motivation, but not every student has a good interest in learning mathematics. But "curiosity" is the nature of students. They are interested in new things and things they know but have never seen. Therefore, to stimulate students' enthusiasm for learning mathematics, we must find ways to arouse students' curiosity. However, traditional teaching and many current teaching are carried out in strict accordance with the syllabus, and students are closed in boring textbooks and monotonous classrooms, completely isolated from rich resources and reality, which leads to a decline in students' interest in learning mathematics. Integrating multimedia information technology into classroom teaching, using the characteristics of multimedia information technology to create various situations for students, such as illustrations, synchronized audio and video, dynamic and intuitive images, can mobilize the participation of students' various senses, stimulate students' strong desire for learning, and stimulate their learning motivation and interest. This fully illustrates the role of multimedia information technology in teaching.
Fourth, teaching should be good at using information technology.
Mathematics in middle school is abstract and logical. The comprehensive processing of graphics, images and animations by information technology and its powerful interactive function make the multimedia classroom fully create an illustrated and lively teaching environment, so that students can always maintain an exciting and happy psychological state and stimulate their interest in learning.
Fifth, use multimedia to improve students' practice effect.
