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 The 2007 trial found a statistically significant difference favoring Building Blocks for Math on the Geometry section of the Building Blocks Assessment (effect size 1.40, improvement index +42). → SRA Real Math Building Blocks PreK 2007
Evidence¶
SRA Real Math Building Blocks PreK 2007¶
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 trial of four preschool teachers (53-61 children) from low-income families in New York State over 25 weeks. Appendix A3 reports Geometry means of 15.75 versus 10.64, effect size 1.40, statistically significant, improvement index +42.
"Clements and Sarama (2007) found a statistically significant difference favoring children in the Building Blocks for Math group on one of the two outcome measures assessed in this domain (Building Blocks Assessment of Early Mathematics, PreK–K: Geometry section) and this effect was confirmed to be statistically significant by the WWC."
