刊于《中小学数学》(小学版)2008年第1一2期上徐德兵的《小学毕业生数学思维发展水平研究(个案)》一文,的确是一篇难得的佳作,我们一口气读了两遍后还想再读。仅就这篇文章对数学教学和学生数学思维培养的价值而言,是不可低估的,然而,该文在阐述“由借助具体的量向借助关系进行思维转变”这一思维发展水平特点时,举例“某工厂接到生产120台机器的任务,前3天完成了60%。照这样计算,完成这批生产任务一共要用多少天?”并列出了这道题如下几种解答方法:
The article “Study on the Development Level of Mathematical Thinking of Primary School Graduates (Case Studies)” published in the January-February 2008 issue of “Primary and Secondary Mathematics” (Primary Edition) 2008 is indeed a rare masterpiece. We read both After want to read again. This article is not to be underestimated with regard to the value of mathematics teaching and the cultivation of students’ mathematical thinking in this article. However, this article elaborates on the developmental level of thinking of “changing from thinking through specific relations to using relationships” For example, “a factory received the task of producing 120 machines, completed the first three days of 60%. According to this calculation, the total number of days required to complete the production tasks?” And lists the following questions Kind of solution:
