《几何画板》不仅入门容易,操作简单,而且具有美妙的动画功能,强大的链接功能,准确的作图功能,奇妙的几何变换功能……,尤其可贵的是在几何图形变化中,始终保持几何元素之间的关系不变,这样可以很好地将数与形的潜在关系、几何元素的动态变化关系淋漓尽致地显现出来,为学生观察和发现几何对象之间的数量关系与空间结构关系提供强有力的帮助,是教师进行数学教学的得力助手。实践表明,《几何画板》在实现信息技术与数学课程整合中扮演着越来越重要的角色。尽管《几何画板》在辅助函数、轨迹、平面几何、平面解析几何教学等方面发挥着重要作用,但是在服务立体几何以及空间解析 “Geometric Sketchpad” is not only easy to start, simple to operate, but also has wonderful animation features, powerful linking functions, accurate drawing functions, wonderful geometric transformation functions, etc. Particularly valuable is that in the geometric changes, always maintain the geometry The relationship between elements does not change. This can perfectly reveal the dynamic relationship between the relationship between numbers and shapes and the dynamic changes of geometric elements. It provides students with strong observation and discovery of the quantitative relationship between geometric objects and spatial structure relations. Powerful help is the teacher’s rightful assistant in mathematics teaching. Practice shows that “Geometric Sketchpad” plays an increasingly important role in the integration of information technology and mathematics curriculum. Although “Geometric Sketchpad” plays an important role in auxiliary functions, trajectories, plane geometry, plane analytic geometry teaching, etc., but in service geometry and spatial analysis
