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 i1 Two studies including 18,712 students reported positive and statistically significant effects on science achievement, with an average improvement index of +11 (range +10 to +13). → Knowledge Is Power Program (KIPP) 2018

q2 · i1 · small effect, average effect size 0.29 · quant-synthesis · r2

Two quasi-experimental studies (Tuttle et al. 2015 middle school QED and high school analysis) met standards with reservations; both reported statistically significant positive state standardized science test effects, yielding a "potentially positive effects" rating. Appendix C.3 prints the WWC-computed effect sizes: 0.25 (+10) for the middle school QED and 0.33 (+13) for the high school analysis, and 0.29 (+11) across both studies.

"In the t wo studies that reported findings, the estimated impact of the intervention on outcomes in the science achievement domain was positive and statistically significant."
