Direct linkGeary, David C.; Hoard, Mary K.; Nugent, Lara; Ünal, Zehra E. – Journal of Educational Psychology, 2023
The study tested the hypothesis that there are sex differences in the pathways to mathematical development. Three-hundred and 42 adolescents (169 boys) were assessed in various mathematics areas from arithmetic fluency to algebra across 6th to 9th grade, inclusive, and completed a battery of working memory, spatial, and intelligence measures in…

Hornburg, Caroline Byrd; Devlin, Brianna L.; McNeil, Nicole M. – Journal of Educational Psychology, 2022
Does the timing of children's formal understanding of mathematical equivalence matter for algebra readiness? A change-resistance account (McNeil & Alibali, 2005) predicts that it is beneficial for children to construct a formal understanding of mathematical equivalence in the early grades before overly narrow operational patterns become…

Scofield, John E.; Hoard, Mary K.; Nugent, Lara; LaMendola V, Joseph; Geary, David C. – Journal of Cognition and Development, 2021
Pre-algebra mathematical competencies were assessed for a large and diverse sample of sixth graders (n = 1,926), including whole number and fractions arithmetic, conceptual understanding of equality and fractions magnitudes, and the fractions number line. The goal was to determine if there were clusters of students with similar patterns of…

Geary, David C.; Hoard, Mary K.; Nugent, Lara; Chu, Felicia; Scofield, John E.; Ferguson Hibbard, Dana – Journal of Educational Psychology, 2019
Sex differences in the strength of the relations between mathematics anxiety, mathematics attitudes, and mathematics achievement were assessed concurrently in sixth grade (n = 1,091, 545 boys) and longitudinally from sixth to seventh grade (n = 190, 97 boys). Mathematics anxiety was composed of two facets, one associated with evaluations and the…

Cirino, Paul T.; Tolar, Tammy D.; Fuchs, Lynn S. – Journal of Educational Research, 2019
Algebra I is a crucial course for middle and high school students for successful STEM-related coursework. A key issue is whether students should take Algebra I in Grade 8 versus Grade 9. Large-scale policy studies show conflicting results, and there are few (particularly longitudinal) individual difference studies. In the study, 53 students were…
