Zheng, Xinhua; Swanson, H. Lee; Marcoulides, George A. – Journal of Experimental Child Psychology, 2011
This study determined the working memory (WM) components (executive, phonological loop, and visual-spatial sketchpad) that best predicted mathematical word problem-solving accuracy of elementary school children in Grades 2, 3, and 4 (N = 310). A battery of tests was administered to assess problem-solving accuracy, problem-solving processes, WM,…
