{Reference Type}: Journal Article {Title}: Improving the Usefulness and Use of Meta-Analysis to Inform Policy and Practice. {Author}: Maynard R; {Journal}: Eval Rev {Volume}: 48 {Issue}: 3 {Year}: 2024 Jun 3 {Factor}: 2.121 {DOI}: 10.1177/0193841X241229885 {Abstract}: 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.
