Hassler Hallstedt, Martin; Klingberg, Torkel; Ghaderi, Ata – Journal of Educational Psychology, 2018
Using a randomized placebo controlled design, we examined the direct and follow-up effects (at 6 and 12 months) of a mathematics tablet intervention. Math training focused primarily on basic arithmetic (addition and subtraction facts up to 12), and secondarily on number knowledge and word problems. We investigated the moderating effects of IQ and…

Ching, Boby Ho-Hong; Nunes, Terezinha – Journal of Educational Psychology, 2017
This longitudinal study examines the relative importance of counting ability, additive reasoning, and working memory in children's mathematical achievement (calculation and story problem solving). In Hong Kong, 115 Chinese children aged 6 years old participated in 2 waves of assessments (T1 = first grade and T2 = second grade). Multiple regression…

Powell, Sarah R.; Fuchs, Lynn S. – Journal of Educational Psychology, 2010
Elementary school students often misinterpret the equal sign (=) as an operational rather than a relational symbol. Such misunderstanding is problematic because solving equations with missing numbers may be important for the development of higher order mathematics skills, including solving word problems. Research indicates equal-sign instruction…

Swanson, H. Lee; Jerman, Olga; Zheng, Xinhua – Journal of Educational Psychology, 2008
The influence of cognitive growth in working memory (WM) on mathematical problem solution accuracy was examined in elementary school children (N = 353) at risk and not at risk for serious math problem solving difficulties. A battery of tests was administered that assessed problem solving, achievement, and cognitive processing (WM, inhibition,…

Johnson, Wendy; McGue, Matt; Iacono, William G. – Journal of Educational Psychology, 2005
Disruptive behavior may be associated with poor academic achievement due to covariance with attention problems and low IQ. Evidence is based on clinical samples and on associations between problem behaviors in young children and later achievement difficulties. The contemporaneous relations and their genetic and environmental influences have not…

Bergan, John R.; Parra, Elena B. – Journal of Educational Psychology, 1979
Effects of language of administration on IQ and predictions of letter learning and achievement were investigated for Anglo and bilingual Mexican American preschool children. Significant IQ differences were associated with language of test administration. No significant differences among predictions of letter task performance were obtained for…

Willerman, Lee; And Others – Journal of Educational Psychology, 1979
Adoptive parents and their adoptive and natural children took IQ tests. Speed of solution correlated with verbal IQ and .51 with performance IQ among the parents. Mothers' speed correlated negligibly with scores of adoptive and natural children. Fathers' speed correlated more with their natural than adopted children's performance scores.…
