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 i2 Preschool children in the Building Blocks for Math group scored significantly higher than the business-as-usual comparison group on the Early Mathematics Assessment (effect size 1.06, improvement index +36). → SRA Real Math Building Blocks PreK 2007
Evidence¶

SRA Real Math Building Blocks PreK. (2007). WWC Intervention Report. What Works Clearinghouse, U.S. Department of Education. http://www.gse.buffalo.edu/org/buildingblocks/
q3 · i2 · causal · r2
Randomized controlled trial with 28 teachers and 202 children from low- to mixed-income families in New York State; teachers randomly assigned to intervention or business-as-usual. Appendix A3 reports means of 61.69 versus 53.22, "8.47" mean difference, effect size 1.06, statistically significant, improvement index +36.
"Clements and Sarama (2006) analyzed group differ-ences between the Building Blocks for Math intervention group and the business-as-usual comparison group on one math out-come measure (Early Mathematics Assessment). The difference between groups was statistically significant and favored children in the Building Blocks for Math group."
