Subclaims¶

q2 i? In a preliminary comparison of two course deployments, behavior-aware prompting was associated with Passive inter-query windows falling from 50.0% to 20.7%, with a significant overall profile-distribution difference. → eval-1 q2 i? Task completion among eligible AI users did not differ significantly between baseline (33.3%) and intervention (43.5%) deployments. → eval-2

Evidence¶

eval-1¶

David Barron, Xiaohang Tang, Rezky Dwisantika, Minsun Kim, David H. Smith IV, Jiaming Cui, and Yan Chen. 2026. TutorTrace: A Dataset and Taxonomy for Classifying Learner Behavioral States during AI-Assisted Programming Education. https://arxiv.org/abs/2608.26184 doi:10.48550/arxiv.2608.26184

q2 · i? · causal · r1

Preliminary classroom comparison of Deployment 3 (baseline, n=48 eligible AI users) versus Deployment 4 (intervention, n=85) of the same course and task. The article reports the profile-distribution difference as "𝜒 2(3)=27.55, 𝑝<. 0001" and a learner-level comparison (U=1533, p<.0001), plus more edits (23.7 vs 11.7), runs (2.1 vs 1.0), and activity time (74.9 s vs 47.0 s).

"Passive inter-query windows accounted for 50.0% of valid win- dows in the baseline deployment and 20.7% in the intervention deployment (−29.3 pp)."

eval-2¶

q2 · i? · design · r2

Null secondary outcome in the same between-deployment comparison: task completion among eligible AI users was 33.3% versus 43.5%, "not statistically significant (𝑝=.273)", and the design is confounded. Equivalence was not tested.

"Completion among eligible AI users was 33.3% in the baseline deployment and 43.5% in the intervention deployment. This difference was not statistically significant (𝑝=.273) and remains confounded by the between-session design."

• Sustained deployment surfaced four behavioral archetypes — self-directed, tutor-reliant, late engager, and passive consumer — including patterns invisible to the reactive teaching system — related
• Window 1 profiles complicate the assumption that greater pre-query effort signals better progress: Cold Start learners completed at 97% while Struggling learners completed at 67% — related
