Subclaims¶

q2 i2 Verification showed the largest effect size of all measures (Cramer's V = 0.357, medium effect); test-based verification fell from 33.2% to 13.8%, a drop of 19.4 percentage points. → Sehrish Basir Nizamani 2026 q2 i1 Restricted to instances where the LLM was actually used, the verification shift remains significant (Cramer's V = 0.205, small effect), with test-based verification among users falling from 59.5% to 20.5%. → Sehrish Basir Nizamani 2026 (2)

q2 · i2 · associational · r1

Survey measure of verification methods across individual and team assignments; the quote reports the printed effect size "V=0.357, medium effect". Non-verification more than quadrupled to 32.6% and "Test-based verification fell from 33.2% to 13.8%, a drop of 19.4 percentage points".

"Output verification showed the most pronounced shift of any behavioral dimension measured, with the largest effect size across all measures (𝜒 2(3)=92.99,𝑝<.0001,𝑉=0.357, medium effect)."

q2 · i1 · associational · r1

Sensitivity reanalysis restricted to student-assignment instances where the LLM was used, ruling out TP1 non-use as an artifact; the quote reports the printed effect size "V= 0.205, small effect" and the among-users percentages.

"The shift remains significant (𝜒 2(3)= 26.01, 𝑝<. 0001,𝑉= 0.205, small effect). Among users only, non-verification rose from 3.7% to 8.1%, and test-based verification among users fell from 59.5% to 20.5%, a larger drop than the unconditional figure."

Discussion¶

Related Claims¶

• Students issue fewer prompts on team assignments, a medium-large within-student difference — related
• Self-reported LLM usage collapses at the first team milestone and recovers only partially on later coding-heavy team tasks — related
• Prompting technique distribution shifts in teams, driven by students reporting no technique at all — related
• Role framing shifts toward non-use in team contexts, with non-use more than doubling — related
• Verification is nearly universal among LLM users, and most students combine multiple verification strategies rather than relying on a single one — related
