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.
q3 i1 When SI-PASS participants were compared to all enrolled students who did not volunteer, the experimental group significantly outperformed non-participants (Hedges' g = .26). → Puttaert 2025

Puttaert, N., Dachet, D., Baye, A., Quertemont, E., Leduc, L., Nyssen, A.-S., & Verpoorten, D. (2025). Effects of SI-PASS on a high-risk course – A randomized controlled trial. Learning and Instruction, 95, 102042. https://doi.org/10.1016/j.learninstruc.2024.102042
q3 · i1 · causal · r2
Quasi-experimental comparison of the 184 randomized SI-PASS volunteers against all other enrolled students who took the exam but did not volunteer. The t-test "displays a significant result: (t(696) = 3.15, p = .002)" with "Effect size is Hedges' g = .26" favoring SI-PASS participants.
"When contrasting the academic performance of the experimental group with that of all students enrolled in the course (Hypothesis 1b) who took the exam but who did not volunteer for the scheme, the t-test, this time, displays a significant result: (t(696) = 3.15, p = .002). Effect size is Hedges' g = .26."

Related Claims¶
- Attendance at SI-PASS meetings correlates positively with final exam performance within the experimental group — related
- Students needed to attend at least five SI-PASS meetings before their exam performance significantly improved — related
- SI-PASS group membership (leader) had no effect on exam performance, with only the TOLT logical thinking score predicting grades in multilevel analysis — related
- In a quasi-experimental comparison, SI-PASS participants completed far more online exercises than non-volunteering students (d = .72) — related
- In a randomized controlled trial, SI-PASS participation did not significantly improve final exam performance compared to a waiting-list control group — related
