1. Create situations with the help of information technology to stimulate students' interest in learning.
Interest is a positive emotion, and people's emotions are always generated in specific situations. Using modern educational technology to assist teaching can vividly and intuitively reproduce teaching information to students' senses, and stimulate students' desire to express through the coordinated use of audio-visual organs. In particular, primary school students are young, short in concentration time and poor in persistence. In addition, the classroom thinking activities are tense, and over time, students are prone to fatigue, lack of concentration and decline in learning efficiency. At this time, teachers can make proper use of information technology to create vivid situations through colorful images, vivid animations and realistic sound effects, so as to relieve study fatigue and attract students' attention, thus igniting students' curiosity and stimulating students' interest in learning.
For example, when teaching "cuboid surface area", he used information technology to create an animated scene like a movie: Mom's birthday is coming, Xiaohong decided to buy a gift for her mother, and then made a beautiful cuboid box out of paper to put the gift. The animation shows the problem of how much cardboard is needed to make this box, which arouses the enthusiasm of students and encourages them to learn, explore, discover and create independently. At the same time, real life pictures and beautiful "birthday songs" have changed the boring introduction of new courses in traditional teaching methods, greatly mobilized students' enthusiasm for solving problems and activated their learning motivation. In this process, vivid mathematical situations stimulate students' interest in learning and enhance their interest in learning.
2. With the help of information technology, it is abstract and intuitive to help students explore and discover.
Pupils are young, abstract thinking has not been fully developed, and the acquisition of more knowledge is based on perceptual knowledge. Therefore, in teaching, the whole process can be displayed intuitively by using information technology, which can give students an immersive feeling and promote the enrichment of thinking. The application of modern multimedia information technology such as network information and multimedia teaching software also provides us with powerful situational resources.
For example, in the teaching of deriving the formula for calculating the area of a circle, students cut the circle in groups, and some cut it into an approximate rectangle; Some put round scissors together into an approximately flat quadrilateral; Some put round scissors into an approximate triangle; Others put round scissors into a trapezoid. Students use different methods to derive the calculation formula of circular area from different angles. In this process, students can taste the fun of independent thinking and cultivate their divergent thinking ability. The students were immersed in the joy of victory. The general teaching of deducing the formula of circular area is over here, but the teacher didn't stop there, and asked, "What kind of figure is the easiest combination of circular scissors?" The teacher's questions pushed the students' thinking interest to a climax. At this time, the teacher gave full play to the advantages of multimedia courseware and showed various methods to deduce the formula of circular area one by one. The students quickly summed up the simplest method and explained the reasons. In this way, students can not only know what it is, but also know why, and raise their thinking to a new level.
For another example, when teaching the area derivation of trapezoid, the single graphic change in the book limits the students' enthusiasm for innovation. Therefore, in teaching design, information technology and picture software are used to set up a variety of ladder division, movement and combination, so that students can freely choose their own methods to demonstrate. The boring abstract teaching of mathematics has evolved into a comprehensive course of making their own demonstration courseware, which greatly satisfies students' innovative consciousness. Based on the evolution of graphics in the book, six kinds of graphics have evolved in their demonstrations, all of which can say trapezoid according to the changing process of graphics. This integration process is flexibly used in the computer in the form of information, so that the graphics can be divided, moved, merged or rotated, which vividly reproduces students' different ideas and tastes different combinations, thus completing the derivation of trapezoidal area formula, allowing students to fully experience the joy after innovation and stimulate their enthusiasm for innovation.
3. Using information technology to help students acquire skills and experience.
The application of information technology in teaching can be displayed intuitively and vividly from static to dynamic according to the content of teaching materials and teaching needs. This can not only stimulate students' interest in exploring new knowledge, but also make them learn actively, help them acquire skills and experience, and cultivate students' flexibility and creativity in thinking.
For example, at the beginning of teaching "the knowledge of circle", let students watch cartoons demonstrated by computers. Four animals, a monkey, a rabbit, a puppy and a bear are having a bicycle race. At the end of the game, the students were asked to guess who won the first place. Why? Some students guessed that the puppy won the first prize (because the puppy's wheels are round). The teacher asked again: The white rabbit's wheels are round, too. Why not guess that it won the first prize? Smart classmates will say: the axle of the rabbit wheel is not in the middle. At this time, the teacher asked why the wheel is round and the axle is installed in the middle, so it runs fast and steadily. You will understand after learning this lesson. In this way, the introduction of new courses not only makes use of the transfer of knowledge, but also permeates the practical problems in life, so that students realize that they are not learning mathematics, but solving practical problems in life, and their thinking will be easily activated, which will naturally lead to their interest in learning and desire to explore knowledge, from "I want to learn" to "I want to learn".
For another example, in the teaching of year, month, day and leap year, these are abstract knowledge points, so I use my self-made teaching courseware to show students the dynamic images of "the earth revolves around the sun for one year, the moon revolves around the earth for one month and the earth rotates for one day", showing these ordinary daily lives. In this way, let them be curious about the wonderful universe, stimulate their innovative spirit of discovering knowledge, let students discover conclusions through observation, and gradually cultivate their innovative consciousness and spirit. It can be seen that the use of information technology can create dynamic and static teaching pictures and lively teaching atmosphere. Through vivid pictures and audio-visual synchronous scenes, pleasant music and timely and effective teaching interaction, students can understand and master new knowledge, thus quickly strengthening their understanding and mastery of new knowledge.
4. With the help of information technology, let life enter the math classroom.
Mathematics comes from the reality of life. Learning mathematics in connection with real life can improve students' understanding that mathematics comes from life, stimulate students' enthusiasm for being close to mathematics and experience the fun of mathematics and life. It can be said that real life is both the starting point and the destination of learning mathematics. The content of mathematics teaching should be closely linked with the reality of life, realistic, life-oriented, close to the flavor of life and the characteristics of the times. The application of modern multimedia information technology such as network information and multimedia teaching software provides us with powerful situational resources.
When teaching "Ji He Ji", let students simulate the scene of people queuing to buy tickets, and turn the still picture into a vivid scene. In the lively and interesting life, students have deepened their understanding of cardinal numbers and ordinal numbers and learned to deal with problems in life. Integrate information technology into primary school mathematics teaching, make full use of various information resources, and let life enter the mathematics classroom. For another example, in the teaching of knowing time, I used many scene pictures in the courseware, a picture of going to school: there is a clock on the left side of the picture with specific time on it; There is also a picture of Sunday: Sunday, what time to get up, what time to eat, what time to go out to play, what time to go home, what time to have lunch, what time to watch TV and so on. All of them are related to students' real life. They use what they have learned to accurately tell the time of everything, which has been widely used. Students have learned all the knowledge of this lesson in application. Through common examples in life, on the one hand, students can fully feel that time is around and know that time is of great help to life, on the other hand, it can also improve students' interest in learning mathematics.
In a word, the introduction of information technology into mathematics classroom teaching is of great significance for cultivating students' autonomous learning ability, promoting and deepening the learning style of new curriculum reform, and improving teaching quality and efficiency. Integrating modern information technology into primary school mathematics teaching, giving full play to its leading role, creating vivid life scenes and stimulating students' interest in learning. Provide abundant information resources, free students from tedious learning, form a learning atmosphere of cooperation, communication and active exploration, improve classroom teaching efficiency, promote the implementation of quality education, optimize classroom teaching, enhance teaching effect, adapt to the needs of modern education, and effectively cultivate more innovative talents. Using information technology to assist teaching has unique advantages in developing students' subjectivity and cultivating their thinking ability. In teaching, teachers use modern educational technology to assist teaching, create rich scenes, mobilize students' multiple senses to participate in the teaching process, and give full play to the best teaching effect, thus encouraging students to learn, explore, discover and create independently.
