Interest in learning is the learning motivation is the most important component of student learning, it plays an important role. Interest in learning and promote the development of students' intelligence, at the same time, this kind of happy feeling and promote students to learn more interested in mathematics, promote each other between the two, so that more active, effective mathematics learning activities, the psychological quality of the students to develop a more harmonious. In mathematics teaching, teachers how to cultivate and stimulate the students' interest in learning, is a problem of the mathematics teachers must pay attention to the. Training teachers to the students' interest in learning should be penetrated into every link of teaching, throughout the whole process of mathematics teaching, according to the characteristics of the students, using the computer aided teaching more focused in the materials, highlights the strong point. For example, the function of teaching, the computer can draw function image quickly on the screen, reflects the changes of function, and to stimulate the senses of students through the graphics changes, pronunciation and other means, to make teaching vivid and interesting, to stimulate students' interest in learning.
Three, the computer aided teaching can improve the students' learning of mathematics intuition
For example, in a straight line segment, ray, judgment, students on the "line" of knowing, but in the application of uncertain. The author in this part of the courseware design, the animation display line, ray and line, good results. For example, you can make the segment fly from left, and then press the animation stacked on top of the line end play, on the basis of an unlimited extension of X-ray and the segment ends are extended to be a straight line. This is based on the original graphics animation display method to allow students to experience the relationship between line, enhance the characteristics of the "line" of the master.

Four, the computer aided teaching can improve the students' mathematical thinking ability
Thinking ability is the core, to let students brains started up, give full play to the function of the brain in terms of thinking. Pay more attention to the training of thinking ability, to pay more attention to the training of thinking training comprehensive and good quality of thinking. Special attention should be paid to the cultivation of the ability of students to explore, abstract generalization and reasoning ability. One of the main goals of mathematics teaching is to cultivate the students' abstract thinking ability. Computer assisted instruction to a specific image of the media to show to the students, so that they can experience the relationship between image and abstract from. Such as the production of courseware "circle" in the understanding of the author, the proper use of animation, sound and video to students learning environment regulation. Before class, teachers through the media play a CD music, let the students achieve the emotion quotient in devote oneself heart and soul to appreciate the improved, conducive to the development of students' mathematical thinking. In the understanding about the design circle, insert a movie "spin of the earth", the students watch, combined with teaching task to explain, to enable students to understand the process of round from abstract concepts to achieve image feeling deep understanding of circle. Close to the concept, definition and the area of the circle of the formula and summarizes the circle and the conventional teaching, make students more freely, smoothly into the mathematics learning. In the production of each picture, note the clear intention, the conventional mathematics teaching requirements of the basic skills, important thinking method, operation ability and the analysis question, solves the question ability as reflected in the courseware. The picture should pay attention to reasonable link, natural, artificial operation time, make it change order.

Five, the computer aided teaching can improve students' ability to explore, discover
The process of mathematics teaching, in fact is the students under the guidance of teachers, the process of mathematical problem solving methods of research, exploration, then carries on the extension of the process of extension and innovation. Key teachers how to design the mathematics problem, mathematics has become mathematics teaching activities. But the problem arising from the situation, therefore, teachers create situations in the teaching activities has become the core of the organization of classroom teaching. The application of modern multimedia information technology such as network information, multimedia teaching software provides us with powerful situational resources. For example: basic concepts are expressed in a coordinate plane vector and vector in the plane of the teaching courseware, plane vector dynamic use of PowerPoint, the student through the exploration, found the basic concepts of plane vector, a deep understanding of the significance and role of plane vector representation. - related problems on the explanation and the space of four, if let the students to observe the model, make the space plane quadrilateral on the blackboard in the diagram, when most of the students to solve the problems in the class, will come very naturally to think space quadrilateral two diagonals intersect. In teaching the author use three-dimensional geometric sketchpad into basic graphics, spatial quadrangle on-site production of rotary movement of the field lines, add. In moving process to make the students feel the space stereo graphic image, cultivate the students' space observation and thinking ability, so as to enable them to leave space in the process of observation with deep impression two diagonal disjoint, in solving related problems without error. At the same time, the students in the process discovered the concept of noncoplanar lines, the "straight lines in different planes" teaching foundation. Therefore, multimedia information technology, the creation of scenarios as a result, compared to traditional teaching method.
Six, the computer aided teaching can improve the teaching effect
????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? ?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????
Teachers in preparing process, need access to relevant data, the huge stacks only limited resources, and teachers should be a local search, turn the pages, this process takes a lot of time teachers. Network information provides inexhaustible teaching resources for teachers, opened up a shortcut for teachers to carry out teaching activities, as long as the address in the address bar, you can in a very short period of time by downloading they need access to information, greatly saves the teaching time. With the rapid development of computer software technology, the establishment of distance education school educators, to create a huge space, a lot of practice practice software and computer aided test software, let the students in practice and test in the consolidation of the knowledge, skill, determines the direction of the next learning, the individual coaching. At this level, the computer software the function of teachers instead of, such as setting, evaluation, inspection, reduce the burden on teachers. Therefore, the development of teaching has a strong dependence on technology, the multimedia information technology teaching aid effect is reflected.

Seven, the computer aided teaching can improve the professional level of teachers and the ability to use the computer
???????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????
The establishment of distance education school educators, to create a huge space, excellent teachers at all levels together in this space, they work in the first line of education teachers provide inexhaustible, teaching resources. Through the network communication, the teacher can learn their advanced teaching thought, teaching idea, teaching method. Practice has proved, often the multimedia information technology in the classroom teaching of teachers, teaching thought, teaching idea, the teaching method is always at the forefront of the. In addition, the teacher application of multimedia information technology and computer aided teaching software in the teaching process, it requires teachers to have a computer skill, computer skill level is one of a new generation standard evaluation of personal and cultural qualities. The rapid development of computer information technology for everyone to put forward new requirements, as teachers, should actively promote the development of computer information technology, the multimedia information technology for classroom teaching, which is conducive to raising the level of their business.
The development of the times, for competitors to improve their own quality, the front also asked the school education in the development, the development of school education also requires teachers to update the teaching means. The renewal of teaching means is mainly controlled by the idea of education, so we should change the concept of education, the application of information technology in teaching. The information technology as a teaching tool, can give full play to the role of information technology in the students' autonomous learning, active exploration, cooperation and exchange and other advantages, to achieve good teacher role transformation. We want to use the One divides into two. perspective computer auxiliary teaching. The computer is one of the mathematics teaching, because of this, it is not possible to completely replace the traditional, but can only play a supporting role. At present, most of the school, because the equipment conditions, popularize the use of CAI in mathematics teaching there are still some difficulties, need to design and development of software is far behind. With the progress of science and technology, computer assisted instruction of mathematics will be developed.
