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 i2 ELs in comparison classrooms with 10% ELs scored 2.65 points lower than non-ELs on the ASK (ES = −.31). → Vaughn 2017

Vaughn, S., Martinez, L. R., Wanzek, J., Roberts, G., Swanson, E., & Fall, A.-M. (2017). Improving Content Knowledge and Comprehension for English Language Learners: Findings From a Randomized Control Trial. Journal of Educational Psychology, 109(1), 22–34. https://doi.org/10.1037/edu0000069

q3 · i2 · causal · r3

Main effect of EL status from the three-level regression on ASK posttest scores in the class-randomized RCT: coefficient −2.65, p < .001, printed effect size ES = −.31. A parallel MASK effect (−1.26, ES = −.26) was also significant.

"The effect of EL status (/H9253200 /H11005/H110022.65, p /H11021 .001, ES /H11005/H11002.31) means that ELs in comparison classrooms with 10% ELs scored 2.65 points lower than non-ELs in the same comparison classroom."
