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 Strategy instruction, the most frequently implemented intervention type, yielded a statistically significant effect of g = 0.36. → Aitken 2026

q3 · i1 · quant-synthesis · r?
Weighted mean effect size for strategy instruction (including SRSD), the most frequently implemented treatment type in the synthesis. The printed effect size is g = 0.36, a small standardized effect: the article reports "strategy instruction ( g = 0.36) was statistically significant".
"With regard to the most often implemented interven - tions, strategy instruction ( g = 0.36) was statistically significant, while process writ - ing (g = 0.51) yielded a meaningful but not statistically significant result."
Discussion¶
Related Claims¶
- Process writing yields a meaningful but not statistically significant effect (g = 0.51) on US ELL students' writing — related
- Writing interventions improve writing quality, the most frequently assessed outcome, with an effect of 0.33 for US ELL students — a broader claim this one bears on
- Writing intervention effects for US ELL students do not vary significantly by study quality indicators, participant characteristics, or intervention characteristics — related
- Writing instruction produces a statistically significant positive overall effect on the writing performance of K-12 English language learners in the United States (g = 0.33) — a broader claim this one bears on
- The pooled effect of writing instruction for US ELL students is robust to sensitivity analyses but funnel plot asymmetry suggests possible missing positive effect sizes — related
