4-6岁儿童数感发展研究

On the Development of Number Sense in Children Aged 4-6

本研究对229名来自中国不同地区的4-6岁幼儿园中班、大班儿童实施《学前儿童数感发展测验》,探究视听模块及类比数量模块等数感能力的发展。研究结果表明:4-6岁儿童数感能力随着年龄的增长而不断提高; 4-6岁年龄段,类比数量模块能力显著高于视听模块能力。两个模块各个子能力在不同年龄段的发展模式存在差异,4-6岁年龄段,口头计算、书面计算能力都保持快速发展,5岁是数点、口头应用、读数、书面应用能力发展的关键时期,而数字线和感知估计能力在这一时期则发展缓慢; 4-6岁儿童数感发展不存在性别差异。

This study,by using the Preschoolers'Number Sense Development Test to test 229preschool children aged 4-6in different regions of China,aims to explore the development of preschoolers'number sense in audio-visual and analog magnitude modules.The results show the following:The number sense of the children aged 4-6improved as they grew older;the children aged 4-6showed a significantly greater ability in the analog magnitude module than in the audio-visual module;the abilities in the two modules varied in different age groups;the children aged 4-6showed rapid development in their abilities in verbal and written calculations;the children aged 5experienced a crucial period in the development of their abilities to count numbers,solve verbal arithmetic problems,read numbers,and solve written arithmetic problems,but they developed slowly in number lines and perceptual estimation;and there was no gender difference between the children aged 4-6in the development of their number sense.
