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 i2 The dimensional comparison-related belief increased significantly directly after the intervention in both groups (Group A d = 0.63; Group B d = 1.34) and at three- and six-month follow-ups. → Hörsch 2026

q3 · i2 · causal · r2

Baseline change models in the math intervention (N = 336) showed "a significant increase in students' dimensional comparison-related belief directly after the participation in the COMPASS intervention in both groups", with d = 0.63 (Group A) and d = 1.34 (Group B); follow-up increases were also significant.

"there was a significant increase in students' dimensional comparison-related belief directly after the participation in the COMPASS intervention in both groups (Group A: MDiff2_1 = 0.57, p <.001, d = 0.63, 95% CI [0.43, 0.82]; Group B: MDiff3_2 = 0.72, p <.001, d = 1.34, 95% CI [1.07, 1.61])"
