Lin, Xin; Peng, Peng; Luo, Hongjing – Learning Disability Quarterly, 2021
The purpose of the study was to compare the deficit profiles of two important types of mathematics difficulties. Three cognitive measures (working memory, processing speed, and reasoning), two mathematics measures (numerical facts retrieval and mathematics vocabulary), and reading comprehension were assessed among 237 Chinese fourth-grade…

Vernucci, Santiago; Galli, Juan Ignacio; Andrés, María Laura; Zamora, Eliana Vanesa; Richards, María Marta; Canet-Juric, Lorena; Burin, Débora Inés – Journal of Research in Childhood Education, 2020
The present study analyzes the psychometric properties of a Spanish-adapted version of the Working Memory Rating Scale (WMRS). This instrument allows teachers to perform a screening of children with possible working memory (WM) difficulties, putting them at risk of academic underachievement. A sample of children age 8.5 to 12.33 years old was…

Jordan, Nancy C.; Hansen, Nicole; Fuchs, Lynn S.; Siegler, Robert S.; Gersten, Russell; Micklos, Deborah – Grantee Submission, 2013
Developmental predictors of children's fraction concepts and procedures at the end of fourth grade were investigated in a 2-year longitudinal study. Participants were 357 children who started the study in third grade. Attentive behavior, language, nonverbal reasoning, number line estimation, calculation fluency, and reading fluency each…

Martin, Rebecca B.; Cirino, Paul T.; Barnes, Marcia A.; Ewing-Cobbs, Linda; Fuchs, Lynn S.; Stuebing, Karla K.; Fletcher, Jack M. – Journal of Learning Disabilities, 2013
The present study evaluated the stability of math learning difficulties over a 2-year period and investigated several factors that might influence this stability (categorical vs. continuous change, liberal vs. conservative cut point, broad vs. specific math assessment); the prediction of math performance over time and by performance level was also…

Hecht, Steven A.; Vagi, Kevin J. – Journal of Educational Psychology, 2010
Results from a 2-year longitudinal study of 181 children from 4th through 5th grade are reported. Levels of growth in children's computation, word problem, and estimation skills by means of common fractions were predicted by working memory, attentive classroom behavior, conceptual knowledge about fractions, and simple arithmetic fluency.…

Raghubar, Kimberly; Cirino, Paul; Barnes, Marcia; Ewing-Cobbs, Linda; Fletcher, Jack; Fuchs, Lynn – Journal of Learning Disabilities, 2009
Errors in written multi-digit computation were investigated in children with math difficulties. Third- and fourth-grade children (n = 291) with coexisting math and reading difficulties, math difficulties, reading difficulties, or no learning difficulties were compared. A second analysis compared those with severe math learning difficulties, low…

Vukovic, Rose K.; Siegel, Linda S. – Learning Disabilities Research & Practice, 2010
This longitudinal study investigated the academic and cognitive characteristics of persistent mathematics difficulty (MD-p) from first to fourth grade. Ninety-nine children were retrospectively categorized into one of three groups: MD-p, transient mathematics difficulty (MD-t), or typically developing. MD-p was defined as persistently low…
