q2 i? The per-semester correlation between average H-score and exam performance was near-zero in 2020–2023 and strengthened to a strongly negative value by Spring 2026. → David Racovan 2026

q2 · i? · associational · r2

Longitudinal observational analysis of six offerings comparing averaged homework H-scores against closed-note, proctored exam percentages per student; the text reports a negative relationship emerging in Spring 2024 and strengthening through "Spring 2026 (𝑟=− 0.537)". Spring 2020 was limited because a project replaced exams beyond Midterm 1.

"Beginning in Spring 2024, a negative relationship begins to emerge (𝑟=− 0.244), and strengthens in Spring 2025 (𝑟=− 0.450) and Spring 2026 (𝑟=− 0.537)."

Discussion¶

Related Claims¶

• Students received significantly higher homework scores during GenAI-evaluation periods, but this advantage did not transfer to downstream exams — the general claim this finding bears on, with the studies behind it
• Average H-scores rose from near-zero in pre-LLM offerings to 11.9 in Spring 2026, with maximum scores reaching 81 — related
• Random measurement noise in pretest scores produces a negative contribution to the correlation between normalized gain and pretest score — related
• High-ability students' learning behaves as a dominant α-process even at low pretest scores, while average-ability students show more γ-process behavior — related
• Students who withdrew after Midterm 1 had higher H-scores than course completers, with the gap widening by Spring 2026 — related
