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 i? The omnibus two-way ANOVA on reading comprehension showed a significant Proficiency × Material interaction, F(4, 126) = 7.43, p < 0.001, η2p = 0.191. → Gao X 2026

q3 · i? · causal · r2
Two-way ANOVA (Table 7) on reading comprehension with proficiency, material condition, and their interaction in a 3×3 between-subjects design (N = 135). The interaction "F(4, 126) = 7.43, p < 0.001, and η2 p = 0.191" located heterogeneity across proficiency strata.
"reading comprehension varied by proficiency, F(2, 126) = 56.81, p < 0.001, and η2 p = 0.474, material condition, F(2, 126) = 8.81, p < 0.001, and η2 p = 0.123, and Proficiency× Material, F(4, 126) = 7.43, p < 0.001, and η2 p = 0.191."
Discussion¶
Related Claims¶
- EAP task performance showed the same directional pattern as reading comprehension but with a weaker Proficiency × Material interaction — related
- Differentiated-AI EAP versions showed limited passage-level structural separation, with automated complexity metrics failing to classify intended proficiency labels — related
- Immediate unsupported application on a new passage showed no material-condition effect and no Proficiency × Material interaction, indicating no short-term dependence cost — reports the opposite
- Posttest reading comprehension differed significantly across the three semantic mapping conditions overall — related
- The three treatment groups were equivalent in reading comprehension at pretest — related
- Differentiated-AI materials exceeded unified-AI materials on reading comprehension within each proficiency stratum, most strongly for high-proficiency learners (d = 1.40) — related
- Expert EAP reviewers rated GenAI-generated differentiated materials favorably for academic fidelity, proficiency appropriateness, and teachability — related
