Senior high school mathematics curriculum should advocate the use of information technology to present the course content that is difficult to present in previous teaching, and encourage students to explore and discover by using computers and calculators. The progress of society puts forward new requirements for teaching content, and also provides new technical means for teaching and new learning methods for learning. The application of information technology in mathematics teaching makes up for the shortcomings of traditional teaching, improves teaching efficiency, and also cultivates students' information technology skills and problem-solving ability. The integration of information technology and mathematics teaching mainly has the following functions.

First, stimulate interest in learning and cultivate awareness of participation.

How to stimulate students' enthusiasm for learning is the key to a good class. For nearly half a century, China's education has been deeply influenced by Kailov's educational thought of attaching importance to cognition and neglecting emotion, and schools have become a single place for imparting knowledge. This leads to the narrowness and closeness of education, which affects the overall improvement of talents' quality, especially the cultivation and development of emotional will and creativity. Situational education is embodied in mathematics teaching, which requires teachers to attach importance to the cultural value of mathematics and create problem situations that are conducive to quality education today.

For example, when learning the maximum and minimum values of the basic properties of a function, you can put a spectacular fireworks clip first. Chrysanthemums are in full bloom. It is generally expected to explode at the highest point when manufacturing. So, how to determine the relationship between the height h of fireworks from the ground and the time t? If the relationship between the height h of fireworks off the ground and time t is h (t) =-4.9T2+14.7t+18. When is the best time to set off fireworks? What is the height from the ground at this time? It is very interesting to let students feel mathematics by creating problem situations. Mathematics not only exists in the classroom and college entrance examination, but also has its value everywhere. Situational teaching can promote the teaching process to become an activity that constantly arouses students' great interest and constantly explores the field of knowledge. With the powerful graphic processing function of multimedia and new teaching methods, we can create vivid and interesting situations, stimulate students' learning emotions, satisfy their innate curiosity and thirst for knowledge, and provide students with an environment for independent exploration and cooperation.

Second, cultivate imagination.

Professor beveridge said: "Originality often lies in finding similarities between two or more research objects, but at first it is thought that these objects or ideas are unrelated to each other." This ability to make two unrelated concepts accept each other, which some psychologists call "long-distance imagination" ability, is an important indicator of creativity. Let students imagine between two seemingly unrelated things, which is like giving students a galloping space. Therefore, in teaching, we can make full use of all imaginable space, tap the factors of developing imagination and give full play to students' imagination.

For example, in the teaching of compulsory course 2- solid geometry, it is difficult for students to understand the meaning of the sentence "light projects from front to back, from left to right and from top to bottom" when they just learn three views of space geometry. Using the dynamics and visualization of the geometric sketchpad, we can create an environment for actually "manipulating" geometric figures. As shown in the figure below, students can observe the light projected from the front of the hexagonal cone to the back, and get the projection A-this is the front view of the hexagonal cone; The second is that the light is projected from the left side to the right side of the hexagonal cone, and the projection figure B is obtained-this is the side view of the hexagonal cone; The third is that the light is projected from the upper surface of the hexagonal cone to the lower surface, and the projection C is obtained-this is the top view of the hexagonal cone. Through observation, some students also vividly concluded that the three views of geometry actually "compressed" geometry from front to back, from left to right and from top to bottom, and painted the "compressed" graphics into "three views" of geometry.

Third, cultivate the ability of autonomous learning.

In mathematics teaching, we should give students the initiative to learn, create colorful activity situations in teaching, and let students practice and explore boldly.

The new mathematics curriculum standard points out that mathematics learning should be a vivid, active and personalized process. Multimedia network technology communicates teachers and students with its own characteristics, attracts students with its rich resources and vivid situations, and makes the classroom form more free and free. You can swim alone in the ocean of knowledge, or you can join hands to overcome the difficulties.

For example, by learning exponential function, we can find many properties by setting up some inquiry activities and using models to make graphics move. We should make full use of the information technology environment, tap the activity factors in the teaching materials, create a classroom environment and an open extracurricular environment for students to actively participate, think and explore, and complete the meaning construction of knowledge. Specific activity forms can be designed at will, as long as they conform to the knowledge structure and are suitable for students. Of course, teachers are still indispensable external factors. They are the organizers, leaders and promoters of students' learning process. If students are found to have encountered obstacles or made mistakes, they can teach students in accordance with their aptitude and give guidance in time, which makes it easier for students to study smoothly. At the same time, it also cultivates students' unity and cooperation ability, competitive consciousness and good collectivism.
