Subclaims¶

q2 i? 10 of 24 top-quartile students reported never using AI for mechanics at pre versus 3 of 22 bottom-quartile students, a cross-sectional pattern equally consistent with struggling students seeking help or heavier reliance displacing practice. → Shuang Geng 2026

q2 · i? · associational · r1

Cross-tabulation of self-reported baseline mechanics AI use against midterm grade quartile (Q4 = top quartile) in the merged, de-identified dataset (n=105, quartile composition reported in Table 1). The pattern is explicitly cross-sectional and descriptive.

"Mechanics-specific use at baseline, however, was inversely related to performance: 10 of 24 top-quartile students (Q4) reported never using AI for mechanics at pre, against 3 of 22 in the bottom quartile (Q1), where 14 of 22 already reported weekly use."

Discussion¶

Related Claims¶

• The RCT is considered the gold standard of research evidence because randomization ensures only the intervention could cause treatment-control outcome differences — the general claim this finding bears on, with the studies behind it

• 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

• Student generative AI use expanded substantially within engineering mechanics coursework over the semester, from 37% to 51% using it at least weekly — related
