小学儿童量度同构概念发展的调查研究

本文试图探索小学儿童形成量度同构概念的规律。在研究中我们调查并测试了一至六年级的儿童。结果表明影响儿童形成量度同构概念的因素主要是 :(一 )儿童思维水平的限制 ,即大多数儿童处在具体运算阶段 ;(二 )小学数学教学中过分强调三量关系式的影响作用。我们认为大约在小学二年级就可以对儿童渗入两组对应的量 (即四个量 )的思想 ,促使儿童尽早进入形式运算阶段

An Investigation on the Development of Primary School Pupils Isomorphism of Measurement

This article makes attempts to study the law in the establishment of school children's isomorphic concept.The studies show that there are a major factors which influence the establishment of school children's isomorphic concept:1. the limitation of children's thought;2. the overemphasis of the effect of three figure relation in math teaching.It is suggested that school children enter the stage of formal operations as early as possible.
