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 i1 In the 2006 trial, the Building Blocks for Math group scored significantly higher than the Pre-K Mathematics combined with DLM Express group on the Early Mathematics Assessment (effect size 0.49, improvement index +19). → SRA Real Math Building Blocks PreK 2007

q3 · i1 · causal · r2
Head-to-head curriculum comparison within the 2006 randomized trial (21 teachers/152 children). Appendix A4 reports means of 57.32 versus 53.77, mean difference 3.55 from an author-conducted HLM analysis, effect size 0.49, statistically significant, improvement index +19.
"Clements and Sarama (2006) analyzed group differ-ences between the Building Blocks for Math group and the Pre-K Mathematics combined with DLM Express group for one math outcome measure (Early Mathematics Assessment). The difference between groups was statistically significant and favored children in the Building Blocks for Math group."
