Interest is the best teacher. Courseware aided by information technology is not only used to convey the teaching content, but also to change the traditional teaching and learning methods, which is conducive to adjusting the classroom atmosphere, creating learning situations and stimulating students' interest in learning mathematics. Multimedia application can improve students' interest in learning mathematics. A successful teaching class, students' interest in learning must be very high, and information technology is our good helper. Proper use of information technology teaching is more expressive and infectious than traditional teaching methods, which can enable students to acquire knowledge quickly and efficiently, develop their thinking and form their abilities.
When introducing a new class, tell a story with an animation, ask a question, set suspense, create a novel problem situation, and stimulate students' psychology of actively exploring new knowledge. One of the characteristics of mathematics course is abstract content. Therefore, how to make a vivid image in the process of imparting knowledge is a problem that mathematics teachers often think about in teaching practice. The application of information technology in mathematics teaching can solve this problem well. For example, in judging straight lines, rays and line segments, although students understand the characteristics of "lines", they are not sure about their application. When designing this part of the courseware, we use animation to display straight lines, rays and line segments. For example, line segments can fly in from the left and then play in the order of animation superposition. A ray is based on a line segment, one end of which is infinite, and both ends of the line segment extend to get a straight line. This method of animation display process based on original graphics allows students to experience the corresponding relationship between lines and deepen their grasp of the characteristics of "lines". Increase the problem scenario design to stimulate the classroom climax.
The previous mathematics teaching courseware was too procedural to reach the climax of learning. If you use the interactive function of AUTHWARE to make your own courseware, you can flexibly combine teaching materials with teaching practice. For example, we have adopted three problem scenarios for the design of the circle of knowledge: 1. What are the manifestations of the circle in life? After the students answer, they call up several circular images from the computer, so that students can concentrate on watching them, and their emotions are high and their ideas are open. In the discrimination of a circle, a drawn wheel image is designed to make students suddenly realize the essence of a circle; In the induction and summary of a class, the main content and problem-solving skills of this class are put on a picture in a close-up way by using network skills and close-up processing, accompanied by relaxed background music, so that students can master the important methods of learning mathematics easily and happily. When I teach the encounter problem, it is difficult for students to accept that it is abstract to find the distance by speed and time. So I used multimedia to demonstrate that two cars came from two places at the same time and met for three hours. Then I use a line graph to represent the distance sum of two cars, and then flash the distance of two cars every hour and merge it into a short line segment, which is the speed sum. After walking for three hours, there are three such small line segments, and their total length is also the sum of the distances between the two cars.
It can be seen that the use of information technology in teaching can successfully create situations and stimulate students' interest in learning. Because multimedia images are concrete, dynamic and static, and sound and emotion are combined, if used properly, it can turn abstract into concrete, mobilize the cooperation of students' various senses, and solve the content that teachers can't explain clearly and students can't understand, thus effectively realizing intensive reading, highlighting key points and breaking through difficulties. At this time, teachers don't need more words, they just need to use information technology to deliver teaching information silently, and show the contents that are difficult to express clearly, vividly and vividly in front of students.
Second, with the help of information technology, collect information and enrich learning content.
Information technology education creates a network learning environment for students to enjoy resources, and completely breaks the shackles of school teaching methods. This comprehensive feature enables our teaching to implement both personalized teaching and cooperative teaching. Through cooperative learning, we can finally learn from each other's strengths and brainstorm, and have a more comprehensive and scientific understanding of the same problem. Great changes have taken place in students' learning concept, and students can carry out "independent discovery and exploration" learning. The website stores a lot of learning information, exercises, troubleshooting and so on. Every student can choose purposeful study according to his knowledge level and interest. This greatly stimulates students' interest in learning, not only cultivates students' ability to search, obtain, analyze and process information, but also creatively improves their own learning methods, which plays an important role in cultivating students' creative thinking development and innovative spirit.
Third, with the help of information technology, let students feel the process of knowledge formation.
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 enable students to learn actively, deepen their understanding of knowledge and cultivate flexibility and creativity in thinking. Using information technology to provide students with an experimental platform for practical operation, exploration and discovery. For example, when teaching the deduction formula of triangle area, how to use the splicing of triangles to deduce the formula of trapezoid area? Besides using the spelling of two trapezoids, you can also use the geometric drawing board to conveniently show that triangles are transformed into known basic figures by means of translation, rotation and folding, so as to further understand the calculation method of trapezoid area and penetrate the transformation idea of mathematics. It can be seen that the use of computer multimedia can create dynamic and static teaching pictures and lively teaching atmosphere, which can further strengthen students' understanding of the triangle area formula in vivid pictures, synchronous audio-visual scenes and timely and effective feedback.
Fourthly, with the help of information technology and virtual reality, knowledge can be restored to real life.
Knowledge comes from life and is applied to life. For example, when learning the content of "knowledge in shopping", students should do shopping and investigation with their parents in the mall before class, and make full use of the powerful tool of computer to give full play to its irreplaceable function and design system.
