数学学习不良的研究及趋势

MATHEMATICAL LEARNING DISABILITY:ITS RESEARCH AND TREND

认知心理学、神经心理学的研究发现了数学学习不良(MD)儿童的3种基本算术技能障碍:语义记忆型MD、程序型MD、视觉空间型MD,并对它们的机制和特征做了考察。近年来对MD儿童较高级数学问题解决的研究呈现如下特点:参与到该研究的领域很多;研究所涉及的认知和非认知因素增多;教学干预研究大量出现。目前MD研究在辨别MD儿童、缺陷的概念以及神经心理学解释上面临挑战。因此该研究领域的趋势是从发展的、整体的视角来考察影响MD的各种因素,并注意各种方法的革新和结合。

Cognitive and neuropsychological research on basic arithmetic skills of MD (mathematical learning disability) children investigated three subtypes of MD, including Semantic Memory MD, Procedural MD and Visuospatial MD. Recent research on higher-level mathematical problem solving of MD children possess three features: fields involved in MD research growing in number;more cognitive and uncognitive factors related to MD being considered;intervening research increasing. The present approach is meeting these challenges including identifying MD children, the defective concept of 'defect,' and the weakness of neurological explanations. The further research on MD should be carried on from developmental and holy perspectives.
