波利亚说过:“数学问题的解决仅仅只是一半,更重要的是解题之后的反思.如果没有了反思,他们就错过了解题的一次重要而有效益的方面;通过回顾所完成的解答,通过重新考虑和重新检查这个结果和得出这一结果的路子,学生们可以巩固他们的知识和发展他们的解题能力”.学生解题往往缺少思维策略,以至于会不假思索地采取某种不恰当的方法或途径,又不能对自己的解题作出清醒的评估,常常一条道走到黑,以至失败.因此,教师要有意识地引导学生对自己的解题活动进行回顾与 Polia said: “The solution to the problem of mathematics is only half, more important is the reflection after the problem solving. If there is no reflection, they miss an important and effective aspect of the problem; completed by reviewing By reconsidering and rechecking this result and drawing the way for that result, students can consolidate their knowledge and develop their problem-solving skills. ”Student problem-solving often lacks a mind-set so that they can think without thinking Take some kind of inappropriate methods or ways, and can not make a clear assessment of their own problems, often one way to black, and even failure.So, teachers should consciously guide students to their own problem-solving activities to review and
