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? No mean treatment differences between Flex and Plain were observed on early literacy or cognitive flexibility growth, and no significant treatment interactions were apparent. → Vadasy 2023

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

In the randomized winter-kindergarten cohort (Flex n = 29, Plain n = 28), multilevel gain models controlling for EB status, pretest, and attendance found "No mean treatment differences were observed" on any outcome. No effect sizes were printed for these contrasts, so impact is not coded.

"No mean treatment differences were observed, nor were any significant treatment interactions apparent (coefficient test ps > .10). In other words, there was no evidence that added practice in cognitive flexibility skills benefitted students’ growth in early literacy or cognitive flexibility beyond the basic phonics intervention."
