“几何画板”是一款优秀的数学教学辅助软件,它简单、易学、功能强大。我校较早就开始利用几何画板进行数学辅助教学的尝试,特别是运用几何画板进行探究性学习,为此,机房的每台计算机都安装了几何画板中文版4．06,每四位学生作为一组共用两台计算机,这使每一位学生都能亲自动手制作课件、进行探究,同时互相之间进行协作讨论,进行充分的合作学习,取得了很好的效果。一段时间下来,我们带领学生进行了蝴蝶定理、圆锥曲线 “Geometric Sketchpad” is an excellent mathematical teaching aids, it is simple, easy to learn, powerful. My school earlier began to use the geometric drawing board for mathematical teaching aids, especially the use of geometric drawing board for inquiry learning, for which each computer room installed Geometry Sketchpad Chinese version 4.06, every four students as a A group of two computers are shared, which makes every student can personally create courseware, to explore, at the same time collaborative discussions between each other, the full cooperative learning, and achieved good results. For some time, we led the students to the butterfly theorem, the conic curve
