由于对《几何画板》认识还没有深入研究,许多老师在利用画板动态探究数学问题的过程中会碰到困难.随着探索实践的深入、认识的积累,在很多方面会有好的创意.笔者在许多杂志和报刊中看到,《几何画板》的爱好者借助《几何画板》中的一些功能来实现分段函数的图象的作法,也尝试着用,感觉很好,但实践中碰到许多问题.在画板作图中要求:1、函数图象能一次性作出;2、在选择函数 Due to the fact that Geometry Sketchpad has not been deeply studied yet, many teachers encounter difficulties in using the Sketchpad to explore math problems dynamically, and in many aspects, there will be good ideas as exploration and practice accumulate. It has been observed in many magazines and newspapers that “geometric palettes” enthusiasts try to use, feel good, but encounter many in practice with the help of some of the functions found in “geometric palettes” Problems in the drawing board drawing requirements: 1, the function can make a one-time image; 2, in the selection function
