揭示命题规律,探究试题背后的故事,是富有挑战的探索过程.这样的探究过程,需要研究者站在全局的高度,以侦探的眼光进行侦查,从试题所呈现的表象出发,恢复还原命题者的命题思路.这样的探究过程,除了能帮助学生从根源上理解试题的解法,更能帮助老师探明试题命制的来龙去脉,从而有效提高学生的解题水平和教师的解题教学水平,对高中数学的解题教学具有重要的指导意义. To reveal the law of propositions and to explore the story behind the test questions is a challenging exploration process.This process of inquiry requires investigators to stand on the overall situation and investigate with detectives’ .This exploration process, in addition to help students understand the solution to the problem from the root causes, can help teachers to find out the ins and outs of the test questions, so as to effectively improve the students ’problem-solving skills and teachers’ problem-solving teaching skills. High school mathematics problem solving teaching has important guiding significance.
