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)

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."

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"
