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 i3 In a randomized three-group experiment, feedback quality differed significantly by source, with a moderate-to-large effect of feedback source on feedback quality. → Farrokhnia 2026

Farrokhnia, M., Latifi, S., Papadopoulos, P. M., Hogenkamp, L., Gijlers, H., Khosravi, H., & Noroozi, O. (2026). Generative AI offers more, but students revise less: comparing the effects of teacher and AI feedback on student essay revisions.

q3 · i3 · causal · r2
One-way ANOVA in the randomized three-group experiment (teacher, Zero-shot, CoT; 70 bachelor's students) on overall feedback quality scored with a Toulmin-based rubric, showing a significant source effect with ηp2 = 0.15, "indicating a moderate effect size".
"The analysis revealed a significant effect of the feedback source on the quality of feedback, F(2, 67) = 6.09, p = .004, ηp2 = 0.15, indicating a moderate effect size"
Discussion¶
Related Claims¶
- GenAI feedback quality correlates with initial essay quality while teacher feedback quality does not — related
- Zero-shot GenAI feedback quality is statistically comparable to teacher feedback quality — reports the opposite
- Zero-shot prompt type has minimal impact on LLM-human coding concordance — related
- Students' argumentative essay quality improves substantially from initial to revised drafts regardless of feedback source — related
- Reasoning-capable model variants and chain-of-thought prompting yield no measurable improvement in either alignment axis for classroom evaluation — related
- ChatGPT-3.5 feedback on EAP argumentative essays aligns closely with human instructor scoring and identifies surface-level issues, but is less effective on rhetorical structure and contextual nuance — related
- GenAI novices develop prompting strategies through trial and error, starting from zero-shot prompts and refining them after unsatisfactory outputs — related
- Prompting with category information or few-shot examples yields limited improvement in distribution alignment, with zero-shot closest for most models — related
- The ChatGPT group achieves significantly greater essay score improvement than the other three groups — related
- In one study, feedback quality significantly predicts revised essay quality under teacher feedback but not under either GenAI feedback condition, though the conditions are not compared directly — related
