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 all spatial pedagogy behavioural categories, collaborative tasks exhibited higher values in RC3 and RC4, whereas individual tasks showed higher values in RC1 and RC2, with RC5 varying by category. → Yuchen Liu 2026

q2 · i? · associational · r1
Comparison of rotated component scores across 62 annotated classroom activities (44 individual, 18 collaborative) within 34 sessions, tested with Mann–Whitney U-tests corrected by FDR. The results section reports "Collaborative tasks exhibited higher values in RC3 and RC4".
"Collaborative tasks exhibited higher values in RC3 and RC4, whereas individual tasks showed higher values in RC1 and RC2. RC5 differences varied across categories, with higher values observed in individual tasks during Instruction, and higher values in collaborative tasks during Interaction."
