作为适用于几何教学的软件平台,几何画板为老师和学生提供了一个观察和探索几何图形内在关系的环境.由点、线、圆、坐标系这些元素构造基本图形,再通过变换、度量、计算、动画、跟踪等,设计出动态的几何图形,及其动态的函数图象.一、变抽象为形象,使轨迹问题直观化传统的教学,认识轨迹形状是通过方程的形式呈现,这当然也很有必要,但是学生并没有真正看到轨迹,有时并不令人信服.而
As a software platform suitable for geometry teaching, geometric drawing board provides teachers and students with an environment for observing and exploring the inherent relationship of geometric figures, and constructing basic figures from points, lines, circles and coordinate systems, and then through transformation, measurement and calculation , Animation, tracking, etc., to design a dynamic geometry, and its dynamic function of the image. First, the abstraction as the image, the trajectory of the problem of visualization Traditional teaching, understanding trajectory shape is presented through the form of equations, of course Necessary, but students do not really see the track, and sometimes not convincing
