摘要
本研究考察并比较了四至六年级儿童的视觉—空间表征策略、数学问题解决和空间视觉化能力。结果表明 :五、六年级儿童的解题正确率、使用图式表征策略的程度显著高于四年级儿童 ;使用图像表征策略的程度各年级无显著差异。将数学问题分成三个难度等级 ,发现年级差异主要表现在难度等级 1的题目上。另外 ,六年级儿童的空间视觉化能力显著高于四年级儿童。
This research investigated the visual spatial representations,mathematical problem solving and spatial visualization ability of forth grade,fifth grade,and sixth grade elementary school students.The results are as follows:Fifth grade and sixth grade students performed better than forth grade ones in mathematical problem solving and the use of schematic representations.No significant differences in the use of pictorial representations among the grade groups.The mathematical problems were further divided into three different categories on the basis of task difficulty.Grade difference generally existed in the first subsample of these problems.Sixth grade students were more competent in spatial visualization than forth grade students.
