In the high school mathematics teaching of multimedia applications
With China's economic growth, the comprehensive national strength, education is strong emphasis on education, increasing the input has also increased, many schools have multimedia equipment installed in the classroom, it makes the computer aided teaching becomes extremely convenient. And mathematics is a particularly strong logicality, comparative abstraction in the classroom and rational use of multimedia technology can help students understand some abstract knowledge, optimize the structure of classroom, boring mathematical classroom becomes rich and colorful, let students learn in happiness. So in mathematics teaching of multimedia what function? Underneath writer
Talk about their views and experience:
A, optimize the teaching environment, stimulate students' interest in learning
"Knows well, the good pleasure of those of inferior." Interest is the best teacher, is one of the characteristics of mathematics curriculum content abstract, in mathematics classroom teaching, using computer to text, images, audio, animation, forming process information such as sound, and figure, the multimedia teaching system of mathematics teaching, students to understand and grasp the content, make complex cognitive activities of abstraction, and thus become simple and intuitive way for traditional teaching, to the greatest extent stimulate students' interest in study, and make students actively participate in the study. Therefore, considering how in knowledge
In the process, it is a vivid mathematics teachers in teaching practice often think of the problem. But in mathematics teaching of multimedia applications can well solve the problem.
Second, multi-media teaching can help students to cultivate and improve space imagination
One of the main goals of the mathematics teaching is to cultivate students' ability of space. The specific image of multimedia can show students, which can experience with abstract. Image, The advantages of multimedia in students' learning of three-dimensional several when especially prominent. Three-dimensional geometry is the high school mathematics teaching difficulty, considered to cultivate students' ability of space. Students first contact with solid geometry, will face many difficulties. Because the plane three-dimensional graphics, will be drawn from the perspective of influence, throughout the whole. And multimedia technology to display the formation process of change, graphics, can be decomposed into complex graphics, make simple graphics in plane three-dimensional graph, enables the student to move from a different Angle, in different ways, to observe in graphic elements, measure the position relations between the relationship and graphics itself. For example, in the design and manufacture of high solid geometry cone of concept and the properties of courseware, can use the geometric board production respectively by the side of a right triangle, rectangle, right Angle has been in the vertical bottom trapezoid waist line for the rest of the rotation axis, which formed surface into the geometry of the dynamic process, lets the student observe dynamic display of positive thinking, and process of abstracts from the essential attribute of conical, concept and definition method to occur in defining cone. This from the concrete to the abstract thinking, thinking of the transition from perceptual knowledge to the sublimation of rational knowledge transfer situation of good, to strengthen the students' knowledge chart, cultivate students' ability of space imagination.
Third, the use of multimedia teaching to break
In the classroom teaching, often encounter some abstract problems, if only through simple, boring story, it is difficult to image formation in students' mind, favor the student grasp. Multimedia dynamic image taken by the demonstration, rich media, not only can the highly abstract knowledge visual display, and have strong stimulation, help students to grasp the key content of content and difficulties.

Use Of Multimedia In High School Mathematics Teaching
Along with our country economy unceasing growth, the comprehensive national strength is day by day formidable, the country the value degree strengthens day by day the education, unceasingly is also increasing regarding the education investment, many schools already the multimedia equipment setups in the classroom, this caused the computer aided teaching became the great convenience. But mathematics is one is quite abstract, the logical specially strong discipline, the reasonable utilization multimedia technologies may help the student in the classroom to understand that some abstract knowledge, the optimized classroom structure, causes the arid mathematics classroom becomes richly colorful, lets the student study in the joy. What then multimedia has in mathematics teaching to affect? Below the author chats own view and realized:
1. The optimized teaching environment, stimulates student's study interest “to know was inferior, good is inferior happy.”The interest is best teacher, one of mathematics curriculum characteristics is the content is abstract, in mathematics classroom instruction, using the computer to informations and so on writing, image, sound, animation carries on processing, forms the sound, the elephant, the chart, Wen Bingmao the multimedia teaching system, is advantageous and grasps in the student to mathematics course content understanding, causes the complex abstract understanding activity becomes is simple and is direct-viewing, thus the atonement tradition teaching way's insufficiency, the greatest degree stimulates student's study interest, causes the student positive to participate in the study on own initiative. Therefore, considered how to achieve the vivid image in the instruction knowledge's process, is mathematics teacher the question which often thinks deeply about in the teaching practice. But multimedia the application may solve this difficult problem well in mathematics teaching.
2. The multimedia auxiliary teaching may help the student to raise and to enhance one of spatial imagination ability mathematics teaching essential targets raise student's spatial ability. Multimedia can demonstrate the concrete image gives the student, enables its to experience vivid and the abstract relations. The multimedia this superiority when the student studies the solid geometry manifests especially prominently. The solid geometry has been the high school mathematics teaching difficulty, was considered that is raises the student space imagination ability the important way. The student initial contact solid geometry, will encounter many difficulties. Because draws up the solid figure in the plane, will receive the angle of view the influence, with difficulty comprehensive survey overall situation. But the multimedia technologies easy to demonstrate that the graph the formation, the change process, may decompose the complex graph the simple graph, lets the solid figure move in the plane, enables the student from the different angle, to observe by the different way, comprehends the nature which in the graph position relations, the metric relation and the graph itself between various elements' has. For example, when in designs and manufactures the high two solid geometry circular cone the concept and the nature" the courseware, may use the geometry drawing board manufacture respectively the straight line which by rectangular one side, nearby the right triangle angle, the right angle trapezoid vertical base's waist has been at is the rotation axis, the geometric solid dynamic process which other each side revolves which forms the curved surface encircles, lets the student from the observed performance demonstration process the positive thought that then abstracts the circular cone the essential attribute, forms the concept, and with has the type definition law to define to the circular cone. This kind from the concrete thinking to abstract thinking's transition, establishes from the perceptual knowledge to rational knowledge's sublimation's good migration situation, is advantageous in strengthens student's knowledge chart ability, raises student's spatial imagination ability.
3. Utilizes the multimedia teaching to be advantageous in breaks through in the heavy difficulty classroom instruction, will meet some quite abstract question frequently, if only through simple, arid narration, will form the representation very difficultly in the student brains, will not favor the student to grasp. Adopts the multimedia dynamic image demonstrations, uses its rich media, not can only the highly abstract knowledge visual display, and has the strong stimulation, is helpful in the student to key content grasping with the difficult content breakthrough.
