q3 i3 Students receiving natural language feedback were more than twice as likely to eventually reach a correct submission (OR approximately 2.33). → 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 · i3 · associational · r1

Logistic regression at the student–problem level in an IRB-approved classroom study of 215 consenting students, comparing natural language feedback to a no-AI baseline with standard errors clustered at the student level. The authors report "an odds ratio of approximately 2.33" and note students are "more than twice as likely to eventually reach correctness".

"we find that natural language feedback is significantly associated with higher eventual success (β= 0.84 ,p= 0.004 ), corresponding to an odds ratio of approximately 2.33"
