Cj. Mills et al., GENDER DIFFERENCES IN ACADEMICALLY TALENTED YOUNG STUDENTS MATHEMATICAL REASONING - PATTERNS ACROSS AGE AND SUBSKILLS, Journal of educational psychology, 85(2), 1993, pp. 340-346
When a sample of academically talented students in Grades 2-6 was give
n a test of mathematical reasoning ability, boys performed better over
all than girls. The gender differences for mathematical ability appear
ed as early as 2nd grade in samples tested over a 7-year period but va
ried somewhat according to mathematical subskills. There were no subst
antial gender-related differences on tasks requiring students to ident
ify whether enough information was provided to solve a task; however,
boys performed better than girls on tasks requiring application of alg
ebraic rules or algorithms, as well as on tasks in which the understan
ding of mathematical concepts and number relationships was required.
