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 i? Multilevel results show IP explained 98% of between-school variance in lower secondary and 78% in upper secondary school, while remaining a weaker predictor at L1 and L2 in all grades. → Stallasch 2024

Stallasch, S. E., Lüdtke, O., Artelt, C., Hedges, L. V., & Brunner, M. (2024). Single- and Multilevel Perspectives on Covariate Selection in Randomized Intervention Studies on Student Achievement. Educational Psychology Review. https://doi.org/10.1007/s10648-024-09898-7

q3 · i? · quant-synthesis · r2

Multilevel (three-level in grades 1-10, two-level in grades 11-12) design parameters meta-analyzed across the six German samples for the total student population, showing level-specific prognostic strength of IP.

"From grade 5 on, IP was the strongest of all covariate types and showed exceptional prognostic properties at L3, where 98/78% of variance was explained in lower/upper secondary school. Across the entire school career, however, IP turned out to be a weaker predictor at both L1 and L2."
