"This volume provides informed arguments, theory and practical examples based on research about what it looks like when educators, policy makers, and even students, try to rethink and change their practices by engaging in evidence-based conversations to challenge and inform their work. It allows the reader to experience these conversations. Each story reveals the depth of thinking that change requires and gives important insights into the challenge associated with changing thinking and practice. Some of the stories are encouraging and others are frustrating. Taken together, they give insight into "what it takes" for conceptual change that will fundamentally shift educational practice."--BOOK JACKET.
