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.

q2 i? The phonological intervention did not significantly improve any reading outcomes versus a no-instruction control (positive but nonsignificant g = 0.06 to 0.32). → Jeffrey S. Bowers 2021 q2 i? The two interventions adding orthographic and semantic instruction showed similar, significant benefits over the phonology condition across multiple outcome measures. → Jeffrey S. Bowers 2021 (2)

q2 · i? · causal · r?

Morris et al. (2012) intervention study for struggling readers in grades 2–3, described in this commentary: 70 × 30-min phonological lessons including phonics produced no significant improvement on word reading accuracy, spelling, fluency, or comprehension versus no-instruction control (g = 0.06 to 0.32).

"The authors found that the phonological intervention did not signif- icantly improve any reading outcomes (including word reading accuracy, spelling, fluency, or comprehension) compared to a control condition that included no reading instruction, although the effect sizes were positive, ranging from g = 0.06 to 0.32"

q2 · i? · theoretical · r3

In the same Morris et al. (2012) study, the two conditions adding 30 min of orthographic and semantic (including morphological) instruction to each phonological lesson significantly outperformed the phonology-only condition across multiple outcome measures.

"By contrast, the two interventions that added orthographic and semantic instruction showed similar and significant benefits compared to the phonology condition across multiple outcome measures."
