Sections describe the component coding process, implementation details across instructional practices, student supports, organizational structures, educator supports, and assessment/placement. Additional appendices provide WWC database data preparation, effect-size computation, model rationale and notation, regression covariates and priors, and further results on impact distributions and associations between specific components and intervention outcomes.",{"@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
