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? Neither the follow-through (FT) nor the no-follow-through (nFT) TRIAD condition showed a persistent impact on fourth-grade mathematics achievement relative to the original control group at either fall or spring assessment. → Douglas H. Clements 2013

q3 · i? · causal · r2
Two-level cross-sectional HLMs (students nested in schools) estimated separately for Fall 2011 and Spring 2012 REMA 3-5 data from the cluster-randomized trial of 106 pre-K classrooms. Impact estimates were small and non-significant: FT vs CTRL .047 (p=.80) Fall and -.035 (p=.79) Spring; nFT vs CTRL -.089 (p=.62) and -.081 (p=.52). No standardized effect size beyond these impact estimates is printed.
"Table 1 suggests that there is no persistent impact of FT or nFT (when compared with students placed in the control group originally) at either time point."
Discussion¶
Related Claims¶
- Neither the workshop nor the one-on-one intervention affected enrollment in the following semester — related
- During the treatment period, the TRIAD Follow-Through group outperformed both control and pre-K-only groups by end of first grade, while the pre-K-only group no longer differed from control — related
- For African-American children, the FT impact appeared stable at about 0.15 of a standard deviation in fall and spring of fourth grade but was not statistically significant at either time point — related
- In spring of fourth grade, the follow-through condition showed a marginally significant differential impact favoring African-American children (0.32 of a standard deviation) — a narrower finding that bears on this claim
- The Building Blocks pre-K implementation showed positive effects on pre-K mathematics (ES=.72) and kindergarten language competencies, with stronger first-grade effects for those with follow-through — related
