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? Higher pretest early literacy skills predicted 10-12% lower growth on the three taught letter outcomes. → Vadasy 2023
q3 i? Each standard deviation increase in tutoring attendance predicted an 11% increase in word reading and spelling growth, and EB children were predicted to have 6% greater gains in letter sound writing. → Vadasy 2023 (2)
Evidence¶
Vadasy 2023¶
Vadasy, P. F., & Sanders, E. A. (2023). Cognitive flexibility + phonics intervention effects on reading gains. Reading Psychology. https://doi.org/10.1080/02702711.2023.2166636
q3 · i? · causal · r2
From the multilevel models of gains for 57 children, pretest negatively predicted the three taught letter outcomes; the article reports higher-skill students "were predicted to have 10-12% lower growth than average, all else held constant." These are printed percentage predictions, not standardized effect sizes.
"Pretest was found to negatively predict the three taught letter outcomes: generally, students who started out with higher early literacy skills were predicted to have 10-12% lower growth than average, all else held constant."
Vadasy 2023 (2)¶

q3 · i? · causal · r2
Treatment attendance uniquely predicted word-level skill gains: "for each standard deviation increase in tutoring session attendance, there was an 11% predicted increase in word reading and spelling growth." The article also reports EB children were predicted to have 6% greater gains for letter sound writing, with no other EB patterns.
"for each standard deviation increase in tutoring session attendance, there was an 11% predicted increase in word reading and spelling growth"
Discussion¶
Learner Variables¶
- English-Learner Status — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Treatment effects were not moderated by emergent bilingual status, pretest levels, or tutoring attendance — related
- Higher pretest cognitive flexibility predicted greater decoding gains and compensated for lower pretest alphabet knowledge — related
- Only the discussion of the Flex vs. Plain phonics trial reports that, for students with full week-6 attendance, Flex showed greater gains than Plain on taught-letter alphabetics, decoding, and word reading; its results report no treatment differences or interactions — related
- Embedded cognitive flexibility practice showed no overall advantage over phonics alone on growth in decoding, encoding, or cognitive flexibility — related
