This chapter begins with an overview of recent developments that have encouraged and facilitated greater use of research syntheses, including Meta-Analysis, to guide public policy and practice in education, workforce development, and social services. It discusses the role of Meta-Analysis for improving knowledge of the effectiveness of programs, policies, and practices and the applicability and generalizability of that knowledge to conditions other than those represented by the study samples and settings. The chapter concludes with recommendations for improving the potential of Meta-Analysis to accelerate knowledge development through changing how we design, conduct, and report findings of individual studies to maximize their usefulness in Meta-Analysis as well as how we produce and report Meta-Analysis findings. The paper includes references to resources supporting the recommendations. [ABSTRACT FROM AUTHOR]

This study examines prevention practices and perceptions in U.S. schools since passage of federal No Child Left Behind (NCLB) legislation, using survey data from state education agencies (SEA) and a population-based sample of school districts. Only one third of U.S. public school districts rely on evidence-based prevention curriculum in middle schools. Funding from other sources and large size were positively associated with using evidence-based curricula. States and districts differed on their perceptions of high-priority activities, and neither supported the federal priority on student drug testing. The findings suggest that there is a disconnect between what NCLB says and what is fund. [ABSTRACT FROM AUTHOR]
