This study investigated the prevalence of latent classes at risk for reading or math disabilities in elementary-age children whose first language is Spanish. To this end, children (N = 394) in Grades 1, 2, and 3 were administered a battery of vocabulary, reading, math, and cognitive measures in both Spanish and English. Three important findings…

This study investigated whether a latent class of children with math difficulties (MD) or math learning disabilities (MLD) emerged within a heterogeneous sample of learners. A latent class analysis was computed on children (N = 447) in Grade 3 who were administered a battery of math, reading, and cognitive measures. The analysis yielded four…

The purpose of this study was to investigate the effectiveness of explicit, direct, and generative strategy training and working memory capacity (WMC) on mathematical word problem-solving accuracy in elementary schoolchildren. In this study, children in third grade ("N" = 82) identified as at risk for math difficulties (MD) were randomly…

This article synthesizes some of the published literature comparing the cognitive functioning of children with reading disabilities (RD) and children with low reading and low intelligence (low achievers). Research indicates that children with reading disabilities outperformed low achievers on measures of lexical knowledge, syntactical knowledge,…

Hierarchical analysis of a test battery of sentence span, preload, and concurrent memory demand tasks was used to identify subgroups of children with different patterns of memory function. For each subgroup, performance strengths and weaknesses were related to reading, mathematics, and spelling performance. (Author/DB)

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)

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.…
