Subclaims¶

q3 i? Controlling for pretest CELF-P and unit pretest scores, the main effect of group on vocabulary learning was large and statistically significant (Cohen's f2 = .70). → Goldstein et al. 2016 q3 i? Experimental-group learning exceeded comparison-group learning at every unit, from 7.2 times greater at the first unit to 1.9 times greater at the last. → Goldstein et al. 2016

q3 · i? · causal · r2

Cluster randomized trial of 32 preschool classrooms in Ohio and Kansas; the Participants section and Table 1 report 163 children with low vocabulary enrolled (85 experimental, 78 comparison), although the abstract gives 195. Analysed using mixed Poisson regression; the group main effect was significant (group β = 1.58, p < .001, Cohen's f2 = .70), with "a mean gain of 3.40 word points per unit" versus 0.32 in the comparison group.

"The experimental group grew from a pretest mean of 0.60 word point ( SD = 0.25) to a posttest mean of 4.00 ( SD = 1.45), a mean gain of 3.40 word points per unit."

Discussion¶

Learner Variables¶

• Vocabulary — outcome: instruction changes it

Related Claims¶

• Preschoolers learn almost no challenging vocabulary from hearing stories without embedded lessons — related
• Vocabulary learning under embedded instruction declined over the course of the school year — related
• Dosage and preintervention language skills showed little moderation of vocabulary treatment effects — related
• Embedded comprehension lessons did not improve story comprehension relative to story exposure alone — related
• Story Friends produced no group differences on distal standardized language measures (PPVT-IV, CELF-P) — related
• Educators reported high satisfaction with Story Friends, but some found repeated listens and scheduling challenging — related
• Story Friends treatment participants had greater vocabulary gains than comparison participants on unit tests, with large effect sizes — possibly the same claim (merge candidate)
