Confucius said, "Knowing is not as good as being kind, and being kind is not as good as being happy". Psychological research shows that interest plays a great role in human development and social life. It leads people into a colorful world, and the characteristics of various things arouse people's curiosity, attract attention, and urge people to explore and know, thus increasing knowledge, developing intelligence and loving life. As far as mathematics teaching is concerned, the teaching effect will be better only if students are interested in learning content and homework. Therefore, teachers must create opportunities and conditions to guide and cultivate students' healthy and beneficial interests and improve teaching efficiency. The application of information technology in teaching can make full use of its flexible and diverse characteristics, create situations, arouse students' strong interest in learning, and make them learn happily and understand easily.
Second, using information technology to unveil the abstract veil of mathematics.
In many years of teaching, there is a problem that has been bothering me-the abstraction of mathematics makes students fluent in solving book problems, but they are helpless in solving some practical problems in life. How to solve this confusion, and how to make primary school students understand abstract mathematical concepts? The application of information technology in teaching makes my eyes shine. Isn't this the starting point to solve the problem? Use multimedia to connect mathematics knowledge with pupils' life, give full play to tangible, real and vivid advantages in real life, and dispel abstract concepts.
The new curriculum concept holds that the content of primary school mathematics teaching should come from students' real life. In organizing teaching, teachers should combine the original ecological mathematical phenomena and mathematical problems that students love to see in their lives and reproduce them in class, so that students can learn mathematics in their lives, master the knowledge points in books, make abstract concepts easy to understand and feel the close connection between mathematics and life. However, teaching by using life scenes and life phenomena can only be successfully completed with the help of information technology.
Third, the use of information technology to promote students' meaning construction
Mathematical concepts and formulas are highly abstract and rigorous. Pupils mainly think in images. If the teacher explains just to make students understand the knowledge, it will be boring and the students will not be interested. Secondly, it is difficult for students to understand, even if they remember, they just memorize and don't understand knowledge at all. Computer-aided instruction can provide vivid perceptual materials for primary school mathematics teaching process, pave the way for students to build bridges, let students participate in them, help students observe and compare, and gradually master the essence of knowledge, so that students can better understand and understand mathematical concepts, laws and rules. Appropriate use of computer courseware to assist teaching and turn abstraction into image is not only easy for students to watch, but also easy to understand, so as to better complete the learning task. Therefore, with the help of multimedia, it not only enriches students' perceptual knowledge, but also reveals the essential laws of mathematical knowledge, thus simplifying the complex, making the difficult easy and enlightening students' thinking.
Fourthly, using information technology to improve the efficiency of classroom teaching.
The use of information technology makes up for the deficiency of traditional teaching methods. Traditional blackboard writing wastes a lot of classroom time. In teaching, I make courseware for some time-wasting content on the blackboard in advance, and I only need to click a few mouse clicks when teaching. The comprehensive application of sound, light, shape and color in teaching, and the simultaneous action on students' multiple senses, is not only conducive to the formation of appearances, but also conducive to the acquisition and consolidation of knowledge. It can break through the limitation of time and space, increase the density of classroom teaching and improve the efficiency of classroom teaching.
