Subclaims¶

q3 i2 Across Grades 4-6, boys scored significantly higher than girls on Axis language items (partial η2 = .11). → Lowrie 2010 q3 i1 Boys also scored significantly higher than girls on Map language items (partial η2 = .03). → Lowrie 2010

Evidence¶

Lowrie 2010¶

Repeated measures MANCOVA of GLIM scores pooled over Grades 4-6 (possible totals 0-18 per language), with gender as between-subjects factor and Raven's score as covariate. Post hoc tests showed "statistically significant differences across the gender variable for the Axis language" (partial η2 = .11) and for Map language (partial η2 = .03); the other four languages showed no significant gender effect.

"Subsequent post hoc analysis revealed statistically significant differences across the gender variable for the Axis language, F(1, 326) = 13.1, p < .001, partial η2 = .11, and the Map language , F(1, 326) = 3.99, p < .001, partial η2 = .03."

Discussion¶

Learner Variables¶

• Gender — predictor: outcomes differ by group: a gap reflecting circumstances and treatment, not a cause

Related Claims¶

• The overall gender difference across the six graphical languages is statistically significant after controlling for non-verbal ability — a broader claim this one bears on
• Gender differences on graphics items arise on tasks requiring movement between 2D and 3D representations or directional processing, not on 2D-to-2D tasks — related
• The gender gap in graphics decoding remained stable over three years, with no gender-by-year interaction — related
