Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Across 28 matched topics, topic-level assistant question volume is a statistically significant surrogate for aggregate self-reported topic difficulty. → Youssef Medhat 2026

q2 · i? · associational · r1
Survey validation comparing topic-level assistant question volume against self-reported difficulty from an independent mid-semester Qualtrics survey with 280 respondents, ranked and correlated over the 28 topics present in both datasets. The paper reports "𝜌= 0.491 ,𝑝= 0.008" as significant at α = 0.05; no effect-size magnitude beyond the correlation is printed.
"Topic-level question volume correlates significantly with student self-reported difficulty from an independent mid-semester survey (𝜌= 0.491 ,𝑝= 0.008 ,𝑛= 28 topics)"
Discussion¶
Related Claims¶
- Per-topic rank agreement between assistant volume and survey difficulty is strong for 14 of 28 topics, with 5 outliers splitting into late-semester meta-level and concept-introduction topics — a narrower finding that bears on this claim
- Students' self-assessed question specificity was not significantly correlated with their observed specificity — related
- Teachers' reflective prompt levels correlate significantly with the reflective level of their students' responses — related
- TRAT scores correlate only very low-to-low with lecture assessment scores, with significance limited to a few topics — related
