q2 i? Phonics (g′ = 0.32) showed effect sizes similar to phonemic awareness instruction, reading fluency training, auditory training, and color overlays; only phonics was significant, likely due to more studies. → Jeffrey S. Bowers 2021

Critique of the Galuschka et al. (2014) meta-analysis of interventions for children with reading difficulties, as reported in this commentary. Phonics g′ = 0.32 was numerically similar to four alternative interventions; the needed interaction test comparing phonics to other methods was not reported.

"I noted that the effect size for phonics ( g′ = 0.32) was similar to the outcomes with phonemic awareness instruction (g′ = 0.28), reading fluency training (g′ = 0.30), auditory training (g′ = 0.39), and color overlays (g′ = 0.32), and that the only reason why their meta-analysis obtained a significant effect for phonics and not the other measures was that there were many more studies in the phonics condition."
