《小学数学课程标准》强调:数学教学要从学生已有的生活经验出发,让学生亲身经历将实际问题抽象成数学模型并进行解释与应用的过程。这是新课程最显著的特点,即把数学作为人类的一种活动去体验,而数学化就是数学活动的主要特征。什么是数学化?孙晓天教授有一个通俗解释:即从情境中发现数学问题,利用已有的经验和知识,去寻找解决问题的策略,在解决问题的过程中探索新概念、新方法,进入未知的 “Primary Mathematics Curriculum Standard” emphasizes: Mathematics teaching should start from students’ existing life experiences, and let students experience the process of abstracting practical problems into mathematical models and explaining and applying them. This is the most striking feature of the new curriculum, in that mathematics is experienced as a human activity, and math is the main characteristic of mathematical activity. What is a mathematical? Professor Sun Xiaotian has a popular explanation: that is, find the mathematical problems from the context, the use of existing experience and knowledge, to find a solution to the problem of the strategy to solve the problem in the process of exploring new concepts, new methods, into the unknown of
