Subclaims¶

q2 i? Differentiated materials were associated with lower cognitive load for low-proficiency learners (a = −2.54, p < 0.001) and higher discourse awareness for intermediate learners (a = 1.36, p < 0.001), with product estimates crossing zero. → Gao X 2026

q2 · i? · causal · r2

Supplementary bootstrap product-estimate models (5,000 samples) treating material condition as X and process indicators as M within each proficiency level. The article reports these as "descriptive" because process indicators and outcomes were collected in the same session; the intermediate product estimate was 0.16, 95% CI [−0.58, 0.90].

"For low-proficiency learners, differentiated materials were associated with lower cognitive load,a =− 2.54, p < 0.001, and the product estimate wasab =− 0.18, 95% CI [−1.67, 1.89]."
