一、形象性传统教学利用黑板、粉笔、模型、幻灯片等进行静态教学,有时难点无法突破。现代信息技术可以把抽象知识形象化,有助于知识的传授。电脑上的图形可以把黑板上抽象的概念具体化、形象化、直观化。尤其是计算机能进行动态演示,弥补了传统教学方式缺乏直观感、主体感和动态感等方面的不足。运用信息技术可以为数学教学起到事半功倍的效果。例如在教学 First, the image of traditional teaching the use of blackboards, chalk, models, slides, etc. for static teaching, sometimes difficulties can not be broken. Modern information technology can visualize the abstract knowledge and help to impart knowledge. Computer graphics can abstract the concept of blackboard on the specific, visualization, visualization. In particular, the computer can perform dynamic demonstration to make up for the lack of intuitive sense, subjective feeling and dynamic feeling in the traditional teaching methods. The use of information technology can play a multiplier effect for mathematics teaching. For example in teaching
