Subclaims¶

q2 i? The experimental group's learning trajectory was significantly steeper than the control group's, evidenced by a significant group × time interaction [β = 0.52, 95% CI (0.31, 0.73)]. → Zhu Z 2026 q2 i? Baseline proficiency was comparable between groups (experimental 52.37 ± 6.81 vs control 53.04 ± 7.12, p = 0.58). → Zhu Z 2026 (2)

q2 · i? · causal · r2

Quasi-experimental educational outcome analysis with 120 undergraduate music majors (60 experimental, 60 control) over 12 weeks, analyzed with a linear mixed model including Group, Time and Group × Time interaction with baseline covariate and participant random intercepts, fitted by REML. The interaction coefficient was β = 0.52 with 95% CI (0.31, 0.73); the article also reports the observed effect as r = 0.52 in the power discussion.

"The learning trajectory of the experimental group was significantly steeper than that of the control group, as evidenced by the significant group time interaction [β = 0.52, 95% CI (0.31,0.73)]"

q2 · i? · causal · r2

Baseline assessment at week 0 using a standardized grade 6 excerpt test showed comparable comprehensive evaluation D-scores between the experimental and control groups (p = 0.58), supporting group comparability before the intervention. Participants were allocated via stratified assignment by baseline proficiency and instrument.

"Baseline proficiency (week 0 standardized test, grade 6 excerpt) showed comparable D-scores between groups: experimental 52.37 ± 6.81, control 53.04 ± 7.12 ( p = 0.58)"
