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? There were no main effects on standardized reading or math scores; teacher-reported academic competence showed only a non-significant trend favoring IY TCM (b = 0.11, p = 0.074, d = 0.08). → Wendy M. Reinke & Keith C. Herman & Nianbo Dong 2018

q3 · i? · causal · r2

HLM analyses of Woodcock-Johnson III Broad Reading and Broad Math scores and teacher-rated academic competence in the group RCT. The article reports no main effects on standardized scores and a trend on academic competence (b = 0.11, p = 0.074, d = 0.08).

"There were no main effects on standardized reading or math scores. However, teacher-reported academic competence demonstrated a trend favoring students in the IY TCM classroom in comparison to control classrooms (b =0 . 1 1 ,p =0 . 0 7 4 ,d =0 . 0 8 ) ."
