Subclaims¶

q2 i? The study reported positive and statistically significant effects on the Iowa Tests of Educational Development mathematics subtest in ninth grade, all three subtests of the Course 1 CPMP Posttest, and contextual algebra and coordinate geometry subtests of the Course 2 CPMP Posttest, confirmed by the WWC after adjustments for clustering and multiple comparisons. → Core-Plus Mathematics 2010

q2 · i? · causal · r2

Findings from the quasi-experiment by Schoen and Hirsch (2002), the one study meeting WWC standards with reservations; the WWC "confirmed" these effects "after adjustments were made for clustering and multiple comparisons". No effect sizes are printed for these subtests.
