在2016年4月《中小学数学》这一期的《“小题”这样“大讲”》中,厉剑杰老师通过几何画板来辅助教学,解决了一道“将军饮马”的变式题。笔者在阅读时,深深地感受到了学生思维与老师之间思维火花的碰撞。同时,我也为厉老师能用几何画板去验证这道“将军饮马”的变式题的方式感到赞叹。然而对此问题,我不禁产生了一个疑问:把复杂问题简单处理是数学解题过程中常用的思想,但直接用“看”来解决,似乎显得不那么严谨,用几何画板虽
In April 2016, during the “Primary and Secondary Mathematics” issue of this issue, Professor Li Jianjie assisted the teaching through geometry palette to solve the problem of “generals drinking horses” Variant questions. When I read, I deeply felt the collisions between the students thinking and the spark of thinking between teachers. At the same time, I am also amazed at the way Teacher Li can use the geometric drawing board to validate the variant of the “general drink the horse.” However, this question, I can not help but have a question: the simple treatment of complex problems is a common problem in the mathematical problem solving process, but directly with the “look” to solve, it seems less rigorous, although the geometric sketchpad
