This eloquent book examines the complex—and often problematic—relations between education research, policy, and practice, and proposes ways to improve those relationships in the interest of meaningful education reform. Based on the Burton and Inglis Lectures, which Michael Feuer delivered at the Harvard Graduate School of Education in 2004 and 2005, the book begins with an examination of how recent developments in cognitive science have fundamentally changed the way we understand human decisionmaking and rational judgment. It then proceeds to a consideration of how the lessons of cognitive science might inform a more rational—and reasonable—approach to education research, policy, and reform. Moving deftly and with great insight through the worlds of education research and policymaking, Feuer offers practical solutions to the impasses and disconnections that have chronically thwarted workable, sustained education reform.
