改编数学题是数学教师必备的基本功,数学教师在备课、教学、考试命题以及从事教学研究的过程中,经常需要改编数学题,传统的改编数学习题的方法主要依赖于改编者的抽象思维能力和逻辑推理能力,一旦涉及到图形的动态变换,传统的方法就显得黯然失色。 计算机应用软件——《几何画板》,因其具有强大而又快捷的度量功能、计算功能和动态显示几何图形(象)的功能,而这些功能又是人脑及其它工具难以企及的。故运用其改编数学题,方便、快捷,可操作性强,画面显示信息量大,结论准确可靠,探究的区域宽阔,它为改编数学习题提供了全新的工具
Adapting mathematics questions is an essential basic skill for mathematics teachers. Math teachers often need to rewrite math problems in the preparation of lessons, teaching, examination propositions, and engaging in teaching research. The traditional method of reorganizing math problems depends on the abstract thinking ability of the adaptors. And logical reasoning capabilities, once it comes to the dynamic transformation of the graphics, the traditional method is overshadowed. The computer application software “Geometry Sketchpad” has powerful and fast measurement functions, calculation functions, and dynamic display geometry (image) functions, which are difficult to reach with the human brain and other tools. Therefore, the use of its adapted mathematical problems, convenient, fast, operability, the amount of information displayed on the screen, the conclusion is accurate and reliable, the breadth of the area of inquiry, it provides a new tool for the reorganization of the number of questions
