MD儿童与正常儿童早期数学认知差异的研究

该研究采用测验法,考察数学学习不良(MD)儿童的早期数学认知能力,包括计数、数守恒、时空概念、逻辑、计算和操作等方面。被试为城市幼儿园34名MD儿童和30名正常儿童,平均年龄约6.0岁。结果发现:学习不良儿童早期数学能力在逻辑、计算和空间保持上有缺陷,与Johnson、Ginsburg等人的研究结果一致。与以往研究有所不同的是:在计数能力上,MD儿童与正常儿童间差异不明显;在数守恒能力上,MD儿童明显低于正常儿童;空间保持缺陷表现突出,表现为书写数字时的镜像反应、图形的错误表征等。

The Research on Cognitive Differences in Normal and Mathematical Disabled Children

This study is on the mathematical cognition of MD,that includes count,quantity conservation,space-time conception,logic conception,calculation and manipulation.The subjects(ages averaged 6) consists of 34 children with MD and 30 normal children,that were randomly choose from the Kindergartens in Shanghai.The tests were carried out individually.Results suggest that MD exists in early childhood with logic deficiency,calculative deficiency or space deficiency,the view of that is consistent with the prime study of Johnson,Ginsburg,et al.However,between the normal and MD children,there's no difference in count,but quantity conservation of MD is underrate,and MD children are more serious than normal children on space deficiency,usually they writes the opposite number such as 3,4,7,9,10 and describes the wrong figure.
