思维始于问题,任何思维活动都是为了解决某个问题而展开的.人类认识世界的过程就是一个“问题——思维——新问题——新思维——”循环反复的过程.因此,培养中学生的数学思维能力应重视数学问题情境的创设.所谓问题情境,它的内涵有三个方面:第一,个体试图达到某一目标;第二,个体与目标之间存在一定的距离;第三,能激起个体积极的心理状态,即产生思维和努力达到目标的心向.在数 Thinking starts with the problem. Any thinking activity is initiated to solve a certain problem. The process of human understanding of the world is a process of “problem-thinking-new problem-new thinking-“. Middle school students’ mathematical thinking ability should pay attention to the creation of mathematical problem situations. The so-called problem situation has three aspects: first, the individual tries to achieve a certain goal; second, there is a certain distance between the individual and the goal; Can arouse individual’s positive psychological state, that is, to generate thinking and work hard to achieve the goal.
