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.
q2 i? On the ITED math subscale, one out of four qualifying studies found significant positive outcomes for Core-Plus Mathematics students. → Core-Plus Mathematics evidence review 2019

q2 · i? · review · r?
Evidence review of the qualifying studies, in which students were tested each year on a math subscale of the Iowa Test of Educational Development focusing on mathematical thinking and problem solving. The review reports that "one out of four studies found significant positive outcomes."
"On the ITED, one out of four studies found significant positive outcomes but this was sufficient to qualify Core-Plus Mathematics for the “Moderate” category."
Discussion¶

- The effect on SAT math scores was positive but not statistically significant, though large enough to be substantively important (effect size at least 0.25) — related
- Core-Plus Mathematics showed positive, statistically significant effects on ninth-grade ITED math and CPMP Course 1 and 2 posttest subtests after WWC adjustments — possibly the same claim (merge candidate)
- Qualifying Core-Plus studies used within-school matching because participation was by student choice — related
- Core-Plus Mathematics has potentially positive effects on mathematics achievement for high school students, with an average improvement index of +15 percentile points — related
