《义务教育数学课程标准》(2011年版,下同)其中一个最大的变化就是从两基变为四基。也就是从原来的基础知识、基本技能,改变为现在的基础知识、基本技能、基本思想方法和基本活动经验。什么是基本活动经验?史宁中教授认为:基本活动经验是指学生亲自或间接经历了活动过程而获得的经验。实践证明,数学活动经验需要在经历过程中形成,但经历了数学活动并不等于获得了活动经验,如何让学生更好地获得丰富的数学活动经验呢? One of the biggest changes in the “Compulsory Education Mathematics Curriculum Standard” (2011 Edition, the same below) is that it changes from two bases to four bases. That is, from the original basic knowledge, basic skills, to change the basic knowledge, basic skills, basic thinking and basic experience. What is the experience of basic activities? Professor Shi Ningzhong that: basic activities of experience refers to the students themselves or indirectly experienced the activities of the experience gained. Practice has proved that the experience of mathematics activities need to be formed in the process of experience, but experienced mathematical activity does not mean that the activity gained experience, how to make students better access to a wealth of experience in math activities?
