一、将知识视觉化前苏联著名数学家A·H·柯尔莫戈洛夫说过:“只要有可能,数学家总是尽力把他们正在研究的问题从几何上视觉化。”因此,我们在教学时经常会使用多媒体课件来演示本节课要讲的知识内容,这已经成为我们对于信息技术最日常化的应用。“几何画板”是一款非常不错的针对数学教学的专业软件,它具有入门容易、操作简单,具有强大的图形和动画功能等优点,可以满足不同年级的数学教学工作,而且随着其版本的不断提升,其图形界面越来越丰富,操作功能越来越全面,是一款非常实用的数学软件。“几何画板”在数学教学的很多领域里都可以担负起重要的作用,它将书本上的文字转化成图 A. Visualization of Knowledge AH ​​Kolmogorov, a noted former mathematician in the Soviet Union, said: “Whenever possible, mathematicians try their best to geometrically visualize the problems they are studying.” “ , We often use multimedia courseware to demonstrate the content of this lesson in our teaching. This has become our most common application of information technology. Geometry Sketchpad is a very good professional software for math teaching. It has the advantages of easy to get started, simple to operate, powerful graphics and animation functions, etc. It can meet the mathematics teaching work of different grades, and with its Version of the continuous improvement of its graphical interface is more and more rich, more comprehensive operational functions, is a very useful mathematical software. ”Geometric Sketchpad " can play an important role in many fields of math teaching. It converts the text on a book into a graph
