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? In the Marsh et al. (2008) German study, both class-average achievement (generalized other) and choosing a more able comparison target (upward comparison, specific other) had significant negative effects on mathematics self-beliefs, each making unique contributions in a combined model. → Marsh 2008

q2 · i? · review · r1

Narrative review of Marsh et al. (2008), a study in which students completed a mathematics test, nominated a comparison target, and rated mathematics agency. The review reports that in the combined model "the negative effects of both class-average achievement and upward social comparison were significant from a statistical perspective and substantively meaningful."

"the negative effects of both class-average achievement and upward social comparison were significant from a statistical perspective and substantively meaningful"
