q2 i? Across the full practice period, RT propensity has no reliable main effect on learning rate (β = −0.02, p = .534), whereas prior proficiency positively predicts learning rate (β = 0.10, p = .009). → main-effect-1

Regression analysis predicting student learning-rate slopes from the iAFM using RT propensity and prior proficiency, on student-level parameters from the eight tutoring deployments. The article reports no reliable RT main effect and a positive proficiency effect; equivalence was not tested.

"RT propensity shows no reliable main effect on learning rate (𝛽=− 0.02, 95% CI[−0.09, 0.05], 𝑝=. 534), whereas prior proficiency is positively associated with learning rate ( 𝛽= 0.10, 95% CI[0.02, 0.17], 𝑝=. 009)."
