Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i2 Accuracy increased with age (main effect of Age on accuracy, effect size η2 p = 0.081). → Susac A 2014
q3 i2 Reaction times decreased with age (main effect of Age on RTs, effect size η2 p = 0.107). → Susac A 2014 (2)
Evidence¶
Susac A 2014¶
Susac A, Bubic A, Vrbanc A and Planinic M (2014) Development of abstract mathematical reasoning: the case of algebra. Front. Hum. Neurosci. 8:679. https://doi.org/10.3389/fnhum.2014.00679
q3 · i2 · associational · r2
Two-way ANOVA with factors Age (7th vs. 8th vs. 1st vs. 2nd grade) and Gender on accuracy in the computerized equation test with 331 students; printed effect size η2 p = 0.081 for the Age main effect, and "accuracy increased with the age of participants."
"The obtained results for accuracy indicated a statistically significant main effect of Age [F(3,323) = 9.43, p < 0.001, η2 p = 0.081]"
Susac A 2014 (2)¶
Susac A, Bubic A, Vrbanc A and Planinic M (2014) Development of abstract mathematical reasoning: the case of algebra. Front. Hum. Neurosci. 8:679. https://doi.org/10.3389/fnhum.2014.00679
q3 · i2 · associational · r2
Same two-way ANOVA design for reaction times; printed effect size η2 p = 0.107 for the Age main effect, and "Average RT s decreased with the age of participants."
"A corresponding comparison for RT s revealed a statistically significant main effect of Age [ F(3,322) = 12.91, p < 0.001, η2 p = 0.107]"
Discussion¶
Related Claims¶
- Students with higher general cognitive ability are more efficient in equation rearrangement — related
- Misconception-task accuracy increases with age between 12 and 15 years, with no age effect on reaction time — related
- Younger students solve letter equations less accurately than number equations, but this difference disappears by age 16–17 — related
- Students become faster and more accurate in equation rearrangement over a short practice session even without feedback — related
- Students' difficulty rankings of equation types partly mismatch their measured performance, though metacognitive accuracy improves with age — related
