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? Head-to-head comparison of the two randomly assigned packages shows DynEd significantly outperforms Imagine Learning on several subtests in years one and two, while Imagine never significantly outperforms DynEd. → Sarah Humpage and Horacio Álvarez-Marinelli 2014

q3 · i? · causal · r2
Full-sample difference-in-difference comparison of the two treatment groups (n=331), the sample in which inclusion criteria were applied identically to both packages. Table 4c shows Dynedt of 0.409** (picture vocabulary) and 0.540*** (understanding directions) in year one and 0.270* and 0.383** in year two.
"When comparing DynEd against Imagine Learning, DynEd has a significantly greater effect on several subtests in the first and second years. Imagine does not have a significantly greater effect on any subtest."
