Partial correlation between inverse efficiency and Raven's scores controlling for age in the 331-student sample; printed effect size r(307) = –0.22 with 95% CI [−0.32, −0.11], a small-to-moderate correlation; higher ability students were more efficient.

"a statistically significant correlation between equation solving efficacy and cognitive abilities [ r(307) = –0.22 [95% CI: −0.32, −0.11], p < 0.001], indicating that the participants with higher cognitive abilities were generally more efficient in equation solving"

Discussion¶

Learner Variables¶

• General Cognitive Ability — predictor: learners who differ on it differ in outcomes

Related Claims¶

• Stealth assessment estimates of problem solving in Use Your Brainz correlate significantly with external measures (Raven's and MicroDYN) in middle-school students — a broader claim this one bears on
• Raven's and MicroDYN jointly explain 22% of variance in the stealth assessment estimate, with MicroDYN adding 5.7% unique variance beyond Raven's — related
• Students' difficulty rankings of equation types partly mismatch their measured performance, though metacognitive accuracy improves with age — related
• Accuracy and speed of simple equation rearrangement increase with students' age across grades 7–12 — related
