It presents two WWC methodological approaches to clarify how early literacy interventions may influence student outcomes. First, it pilots an expert-developed taxonomy for standardizing component terminology. Second, it applies Bayesian meta-analysis to synthesize evidence across studies and estimate associations between intervention components and observed impacts. Findings identify common components, component domains linked to effects, and explanatory power for variation in intervention results.",{"@graph":14,"@context":72},[15,34,55],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/research-report/","Research
