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? Hirschhorn (1993) found no statistically significant effect in one site and a positive significant effect in another on the Mathematics Level 1 Achievement test; pooled across sites the difference was not statistically significant. → What Works Clearinghouse 2016

q2 · i? · quant-synthesis · r1

Site-level results from the Hirschhorn (1993) longitudinal quasi-experiment diverged across the two sites; the WWC pooled them and found "no statistically significant differences" on the standardized Mathematics Level 1 Achievement Test, so equivalence was not established.

"Hirschhorn (1993) found no statistically significant effects in one site, and a positive and statistically significant effect in another, on the Mathematics Level 1 Achievement test. The WWC pooled the results from both sites and found no statistically significant differences between multiple UCSMP courses and comparison groups on the test."
