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? Children with MD in the materials-only condition scored significantly higher than the MD control group on the experimental STAR measure. → Swanson 2014

q3 · i? · causal · r2
HLM analysis of posttest STAR problem-solving scores in the same randomized Grade 3 study. The article reports that "childrenwithMD inthemate - rials-only conditionyieldedsignificantlyhigher adjustedposttestscoresthanchildrenwithMD in the controlcondition", and a moderate effect size between materials-only and control for children with MD.

Discussion¶
Learner Variables¶
- Problem Solving — outcome: instruction changes it
Related Claims¶
- Combined verbal+visual strategy instruction improves standardized problem-solving accuracy for children with math difficulties — related
- Coherence Principle Irrelevant Material Hurts Learning — reports the opposite
- Interesting but irrelevant details can impair comprehension and transfer, with effects that vary with the material and the learner — reports the opposite
