“猜想”让数学课堂更精彩

“Guessing” and Wonderful Mathematics Classroom Teaching

在数学领域中,猜想是合理的、值得尊重的,是负责任的态度,教猜想比教证明更为重要。在数学课堂中应通过创设情境激趣,构建良好的课堂氛围,采用多种手段,鼓励学生乐于猜想并学会猜想,在顺利解决问题的过程中体验成功、树立自信,从错误的猜想中理清正确的解题思路,可以有效地提高学生的创造性思维能力,培养学生勇于开拓的精神。

Guessing in mathematics is reasonable,respectable and responsible.Teaching students’guessing is more important than teaching argumentation.Mathematics teachers should spark students’interest by creating contexts,construct fi ne classroom atmospheres,and employ various methods to encourage them to guess happily and skillfully.Meanwhile,in the process of solving the problems,students can experience success and build up their confi dence so that they can summarize the right paths of solving the problems from the wrong guessing.In this way we can effectively promote students’creative thinking and develop their pioneering spirit.
