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? With repeated measures, the construct of both MAP reading and mathematics remained consistent at different points in time, which the authors read as support for configural, weak and strong invariance across states except Indiana mathematics. → Wang 2013 q2 i? The text states that all ΔCFI values between nested invariance models were less than 0.01 in both tests, but the mathematics table (Table 8) shows the weak-to-strong invariance drop in CFI exceeding 0.01 in eight of the nine states other than Indiana (e.g. Colorado .985 to .974, Minnesota .967 to .947), so strong invariance in mathematics is less clearly supported than the prose says. → Wang 2013 (2)

q2 · i? · associational · r2

MLGM invariance analyses of MAP reading and mathematics data from a five-wave panel (Spring 2009 to Spring 2011, grades 5–7) in ten states. The study reports "the construct of both reading and mathematics remained consistent at different points in time", supporting CI, WI and SI except Indiana mathematics.

"The evidence collected in the study shows that with repeated measures, the construct of both reading and mathematics remained consistent at different points in time, which supports the internal structure of MAP design for intended purposes."

q2 · i? · associational · r2

Nested linear MLGM model comparisons for measurement invariance across five waves, evaluated with Δχ2 and the Cheung and Rensvold ΔCFI criterion. The article reports "all ΔCFIs less than 0.01 in both tests", so constrained parameters were judged invariant; no effect size is printed. Its own Table 8 does not bear this out for mathematics at the strong-invariance step: CFI falls from weak to strong invariance by more than 0.01 in Colorado (.985 to .974), Illinois (.980 to .967), Kansas (.977 to .957), Kentucky (.982 to .970), Michigan (.980 to .966), Minnesota (.967 to .947), South Carolina (.977 to .965) and Washington (.975 to .962); only Wisconsin (.979 to .970) stays under it, and Indiana's models fit poorly throughout.

"The value of all ΔCFIs less than 0.01 in both tests indicates that constrained parameters are invariant across time."
