This volume draws together interdisciplinary approaches from political philosophy, social work, medicine and sociology to analyze the theoretical foundations and practical examples of evidence-based and evidence-informed education for the public good. It presents a range of conceptions of the evidence-based and evidence-informed education and a justification for why the particular examples or issues chosen fit within that conception for the sake of public good. It explores the current literature on evidence-based and evidence-informed educational policy, research and practice, and introduces a new term, 'evidence free', meaning actions of some policymakers who disregard or misuse evidence for their own agenda.
