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 i2 Teacher feedback total items (316) significantly exceeded AI-assisted peer feedback (185) in task 1, with significant differences in vocabulary errors (Cohen's d = 0.66) and technical details (d = 0.58). → Tang J 2026

q3 · i2 · causal · r2
Independent-samples t-tests comparing feedback items per student across the two classes (control n = 31, experimental n = 30) in the first writing task. Vocabulary errors: t(59) = −2.677, P = .010, "Cohen's d = 0.66"; technical details: t(59) = −2.620, P = .012, d = 0.58.
"In the first task, the total amount of teacher feedback (316 items) was significantly higher than that of AI-assisted peer feedback (185 items)."
Discussion¶
Related Claims¶
- Feedback improves learning by a medium amount on average, but its effect varies widely with the information it carries, and a substantial share of feedback effects are negative — the general claim this finding bears on, with the studies behind it
- Across tasks, teacher feedback shifted from basic error correction toward higher-order dimensions while AI-assisted peer feedback reduced content suggestions and increased technical-detail feedback — related
- AI-assisted peer feedback enhanced lexical diversity only in the first writing task, with the group advantage disappearing by the second task — related
- Teacher feedback produced larger first-task score gains that dropped 32.8% by the second task, while AI-assisted peer feedback gains remained stable (a learning-curve effect) — related
