This study aims at investigating into the general law of the develop-ment of proportional reasoning and internal cognitive structure in Chi-nese children between 4 and 14 years of age. Results: (1) seven stageshad been differentiated through multiple statistical method of cluster analysisof ordered sample and factor analysis with SPSS programs; (2) the gene-ral law indicated: the developmental advance is from one-dimensional,additionally qualitative operation to two-dimensional, multiplicationallyquantitative operation; from one-level integration of additional operation,to two-level integration of operation of the functional relations of anyinteger-multiple equal proportion, finally to top-level integration of ope-ration of the functional relations of non-integer-multiple non-equal pro-portion in the level of proposition. The development of proportional rea-soning is a gradually constructed and integrated process of the four-structure-relations from low to high level; (3)comparing the rate of success betweenChinese and Canadian 11--14 year old children showed that the teachingon ratio and proportion in China was very effective.

本实验研究的主要目的是,探讨4——14岁儿童比例推理能力及内部认知结构发展的一般规律。结果:1.采用有序样本的聚类分析和因子分析,将其发展划分为七个阶段。2.发展的一般规律为:从单维、定性、加法推理到两维、定量、乘法操作;从比差运算上的整合,到整倍数乘法运算上的整合,最终达到在命题运算水平上对非整倍数函数关系操作上的整合;其发展的核心是,四个结构关系由低向高逐渐构建和整合,由此提出四结构关系建构理论。3.小学高年级和中学低年级儿童比例概念基本形成,与加拿大同龄儿童比较,有显著差异,表明国内比例概念的教学是有成效的。
