This study identified cognitive processes that underlie individual differences in working memory (WM) and mathematical problem-solution accuracy in elementary school children at risk and not at risk for serious math difficulties (SMD). A battery of tests was administered that assessed problem solving, achievement, and cognitive processing in…

Two experiments involving 227 children aged 5 to 18 years suggest that working memory operates as a general system independent of the subject's reading skill and that dynamic testing procedures enhance predictions of reading performance. Individual differences in working memory do not appear restricted to an academic domain. (SLD)

Models of working memory were compared in 2 experiments as means of explaining variance in the comprehension of 95 skilled and 80 learning-disabled readers from grades 4 through 7. Results suggest that learning-disabled children's working memory problems are functionally related to higher order processes and not memory alone. (SLD)

Whether high levels of metacognitive knowledge about problem solving can compensate for low overall aptitude was studied for 31 high-aptitude and 25 low-aptitude children in grades 4 and 5. Results confirming superior performance of high metacognitive individuals are discussed in terms of the independence of metacognition and academic aptitude.…
