随着信息技术的发展 ,广大中学数学教师越来越重视应用计算机辅助教学 .数学学科的数形结合的特点 ,抽象与具体的关系 ,运动与变化的本质以及数学活动的探索性 ,需要计算机辅助教学 ,它可以为抽象的问题提供直观的背景 ,使复杂的“数”通过“形”来表示 ,为数学活动提供了探索? With the development of information technology, the majority of middle school mathematics teachers are paying more and more attention to the use of computer-assisted teaching. The combination of mathematics and mathematics, abstract and specific relationships, the nature of movement and change, and the exploratory nature of mathematics, computer-aided Teaching, it can provide an intuitive background for abstract problems, so that the complex “number” is represented by “shape”, which provides an exploration for mathematics activities?
