q2 · i? · associational · r1

Descriptive comparison (Figure 8) of midterm scores for 21 classified LLM users: 14 in the LLM-driven support group and 7 in the student-driven group, assigned by their three most frequent usage types; 2 students were unclassified. No statistical tests were conducted due to imbalanced group sizes. The discussion reports a 10% difference on the first midterm.

"students in the student-driven group scored higher on Midterm 1, but the performance of the two groups converged in subsequent midterms."

Related Claims¶

• Students who used LLMs on assignments scored significantly lower than non-users on the first midterm (large effect size), but this gap narrowed and was non-significant on the later midterms — related
• Among LLM users, Low-Reliance students (use in under half of submissions) consistently outperformed High-Reliance students by roughly 7-8% across all three midterms — related
• Individual trajectories suggest heavy LLM use focused on support other than full answer generation can coexist with improving scores, whereas reliance on LLM-generated summaries was associated with declining scores — related
