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 multisite cluster randomized controlled trial of 122 fourth-grade teachers, classroom-level TerraNova Basic Battery math scores did not differ significantly between Odyssey® Math and comparison classrooms, and the effect was not substantively important. → wijekumar-1

wijekumar-1¶
U.S. Department of Education, Institute of Education Sciences, What Works Clearinghouse. (2017, January). Primary Mathematics intervention report: Odyssey® Math. https://ies.ed.gov/ncee/wwc/InterventionReport/669
q3 · i? · causal · r3
Cluster randomized controlled trial across 32 schools in Delaware, New Jersey, and Pennsylvania; 122 teachers teaching 2,456 students analyzed as teacher-level means on the TerraNova Basic Battery. The review reports "no statistically significant difference" and characterizes the effect as indeterminate.
"Wijekumar et al. (2009) reported, and the WWC confirmed, no statistically significant difference between the Odyssey® Math and comparison groups on the mathematics achievement domain."
