秉着培养学生的实践能力和创新意识 ,加强数学素质教育 ,我尝试着对课本一道例题进行改造 ,打破问题条件和结论唯一性结构的限制 ,从而提出了一个开放性问题 .由于问题的解决过程具有可操作性、解答的不确定性以及条件的发散性等特点 ,留给学生的实践机会很多、思维空间很大 ,
In order to cultivate students’ practical ability and innovation consciousness and strengthen mathematics quality education, I tried to reform the examples of textbooks to break the limitations of the problem conditions and the uniqueness of the conclusions, thereby presenting an open question. Because of the problem solving process With features such as operability, uncertainty of solution, and divergence of conditions, there are many practical opportunities for students and there is a lot of room for thinking.
