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? The WWC identified seven eligible studies; no study met group design standards without reservations, one met them with reservations, and the remaining six did not meet standards. → wwc-research-summary

Evidence

What Works Clearinghouse, Institute of Education Sciences, U.S. Department of Education. (2017, July). Primary Mathematics intervention report: I CAN Learn®. Retrieved from https://ies.ed.gov/ncee/wwc/InterventionReport/676

q2 · i? · review · r3

Review of 40 identified studies: seven fell within the Primary Mathematics scope and were reviewed against group design standards; six did not meet the standards, leaving a single quasi-experimental study (Kerstyn, 2002) as the basis for the effectiveness rating. The extent of evidence for the mathematics achievement domain is rated small.

"None of the seven studies is a randomized controlled trial that meets WWC group design standards without reservations. One study uses a quasi-experimental design that meets WWC group design standards with reservations."
