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 i1 Students with MD-PS in SBI classrooms scored on average 0.32 SDs higher than control students on the PPS total posttest, a printed standardized effect of 0.32 SDs. → Jitendra 2017

q3 i? Students with MD-PS in SBI classrooms scored on average 0.32 SDs higher than control students on the PPS total score at immediate posttest. → Jitendra 2017

Jitendra, A. K., Harwell, M. R., Dupuis, D. N., & Karl, S. R. (2017). A Randomized Trial of the Effects of Schema-Based Instruction on Proportional Problem-Solving for Students With Mathematics Problem-Solving Difficulties.

q3 · i1

Two-level HLM analysis of posttest PPS total scores for 806 students with MD-PS in 82 randomly assigned classrooms, controlling for pretest and demographic covariates. The treatment coefficient was significant (p = .004), with a printed standardized effect size of 0.32 SDs: SBI students scored "on average 0.32 SDs higher than those in the control group".

"treatment was a significant predictor of PPS total posttest scores ( γ01ˆ = 1.17), which translates to SBI students scoring on average 0.32 SDs higher than those in the control group, and a 22% reduction in the conditional intercept variance attributable to treatment"
