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? Principal component analysis of rubric items supported separating authentic online work into higher-order thinking and real-world relevance subscales. → Darling-Aduana 2021

q3 · i? · design · r2
Psychometric validation study of the Authentic Online Work Rubric using lesson-level data from online courses developed by one of the largest U.S. online course providers. The article reports that the author "validated the scale using principal component analysis" before IRT scoring of both subscales. No component loadings or fit statistics are printed in the available text.
"I validated the scale using principal component analysis before generating a lesson-level standardized coefficient using item response theory for both the higher-order thinking and real-world relevance subscales."
