Recent intervention studies directed to improve problem solving accuracy in children with math difficulties (MD) have found support for teaching cognitive strategies. This study addresses the question: What role does working memory capacity (WMC) play in strategy outcomes for children with MD? Four prediction models can be applied to strategy…

This study determined the working memory (WM) components (executive, phonological short-term memory [STM], and visual-spatial sketchpad) that best predicted mathematical word problem-solving accuracy in elementary schoolchildren (N = 392). The battery of tests administered to assess mediators between WM and problem-solving included measures of…

This paper provides a rationale for basic research and metatheory development in the field of learning disabilities, outlines the steps and cognitive parameters involved in validating such a metatheory, and discusses integrating the findings of basic research with instructional manipulations and reasons for the poor integration of theory and…
