New WWC Methodological Report on Using Bayesian Meta-Analysis to Explore the Components of Early Literacy Interventions

This WWC methodological report explores to what extent components of early literacy interventions can explain which interventions have positive effects on alphabetics outcomes. The components examined in this report have a limited role in explaining variation in intervention effects, but this report identified positive associations between intervention impacts on alphabetics outcomes and components related to using student assessment data to drive decisions and teaching social-emotional learning strategies.
