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? Of 34 eligible studies identified, only one quasi-experimental study (Waite, 2000) met WWC group design standards (with reservations); no studies met the standards without reservations. → evidence-base
Evidence¶
evidence-base¶
U.S. Department of Education, Institute of Education Sciences, What Works Clearinghouse. (2015, November). Primary Mathematics intervention report: Everyday Mathematics®. https://ies.ed.gov/ncee/wwc/InterventionReport/166
q2 · i? · review · r3
The WWC systematic review screened 92 identified studies; 34 were eligible for review against group design standards. Thirty-three eligible studies did not meet WWC group design standards, most commonly because "equivalence of the analytic intervention and comparison groups is necessary and not demonstrated." The extent of evidence is rated small: one study with 3,436 students in 18 schools.
"The WWC identified 34 eligible studies that investigated the effects of Everyday Mathematics® on mathematics achievement for primary stu-dents. An additional 58 studies were identified but do not meet WWC eligibility criteria for review in this topic area."
