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? At any given attempt, students receiving natural language feedback were approximately 9% more likely to succeed than those receiving no feedback (HR = 1.09, p = 0.03). → Hasnain Heickal and Andrew Lan 2026
Evidence¶
Hasnain Heickal and Andrew Lan 2026¶
Hasnain Heickal and Andrew Lan. (2026). A Classroom Study of LLM-Generated Feedback Intervention in Introductory Programming. https://arxiv.org/abs/2606.08807 doi:10.48550/arxiv.2606.08807
q3 · i? · associational · r2
Cox proportional hazards models with right censoring, measured in submissions since first feedback exposure, in the same classroom study. The authors report "HR = 1.09" and note the significant hazard ratio "indicates that this effect reflects faster convergence, not merely a ceiling-driven success rate difference".
"natural language feedback is associated with a modest but significant increase in the hazard of reaching correctness (HR = 1.09,p= 0.03 ): at any given attempt, students receiving natural language feedback are approximately 9% more likely to succeed"
