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…

Arithmetic word-problem solving is an important component of elementary mathematics curricula that links school mathematics to real-life problem solving. The present 3-year longitudinal study examined children's arithmetic word-problem solving through understanding its 2 component processes: number-sentence construction and computation. Chinese…

This study added extraneous information and increased syntactical complexity to determine the relative importance of computational and reading abilities in solving arithmetic word problems. Analyzing tests of 200 sixth graders indicated the combined abilities accounted for 54 percent of the variance in solution accuracy. (BS)
