q3 · i? · quant-synthesis · r2

WWC synthesis of three randomized controlled trials (Pinnell, DeFord, & Lyons 1988; Pinnell et al. 1994; Schwartz 2005) including 227 first-grade students. Table 1 reports a "Positive effects" rating with improvement index "+27" (range +19 to +38) and a small extent of evidence; no standardized effect size is printed, so impact is null.

q3 · i? · review · r3

The effectiveness summary states that "three studies with strong designs reported statistically significant positive effects" in the general reading achievement domain, on measures including the Observation Survey subtests, Gates-MacGinitie, and Woodcock Reading Mastery Test–Revised. No effect size is printed for this domain-level finding.

"Thus, for the general reading achievement domain, three studies with strong designs reported statistically significant positive effects. This results in a rating of positive effects, with a small extent of evidence."
