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.
q3 i? In a multischool experimental study of first graders (the summary read does not say how schools were assigned), schools assigned to Math Expressions and Saxon Math achieved significantly higher math achievement than schools assigned to Investigations in Number, Data, and Space and Scott Foresman-Addison Wesley Mathematics. → Agodini 2009

q3 · i? · causal · r?
Findings from the first cohort of a large-scale federal experimental study of four early math programs, based on 39 schools that began participation in the 2006-2007 school year. The report states "achievement was significantly higher in schools assigned to Math Expressions and Saxon Math" than in the two comparison curricula; no effect size is printed on this page.
"Researchers found that achievement was significantly higher in schools assigned to Math Expressions and Saxon Math than in schools assigned to Investigations in Number, Data, and Space and Scott Foresman-Addison Wesley Mathematics."
