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? Graded-response item response theory scoring produces a lesson-level standardized coefficient for the higher-order thinking subscale and for the real-world relevance subscale. → Darling-Aduana 2021

q3 · i? · design · r2
Scale-scoring analysis following PCA, applied to lesson observations from a large U.S. online course provider's courses. The article reports generating "a lesson-level standardized coefficient using item response theory" for each subscale; specific IRT parameters are not printed in the supplied 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."
