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.

q1 i? In contrast to cognitive variables like intelligence or prior knowledge, motivational variables rarely explain more than 10% of variance in behavior and outcomes. → Reinhard Pekrun 2024

q1 · i? · theoretical · r3

The commentary cites prior syntheses (Hattie et al., 2020; Noetel et al., 2023; Richardson et al., 2012) to support the claim that motivational variables rarely explain more than 10% of variance, using this as evidence that fundamental change in motivation theory may be overdue.
