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? Based on one quasi-experimental study meeting WWC standards with reservations, Core-Plus Mathematics was rated as having potentially positive effects on high school mathematics achievement, with an average improvement index of +15 percentile points (range –15 to +36). → Core-Plus Mathematics 2010
Evidence¶

q2 · i? · causal · r2
WWC synthesis of one quasi-experiment (Schoen & Hirsch, 2002) using a student matched-pairs design in 11 high schools, including 1,050 students in year one. The report states the "average improvement index for mathematics achievement is +15 percentile points in the one study".
"The average improvement index for mathematics achievement is +15 percentile points in the one study, with a range of –15 to +36 percentile points across findings."
