"The issue of what constitutes credible evidence isn't about to get resolved. And it isn't going away.This book explains why. The diverse perspectives presented are balanced, insightful, and critical for making up one's own mind about what counts as credible evidence. And, in the end, everyone must take a position. You simply can't engage in or use research and evaluation without deciding what counts as credible evidence. So read this book carefully, take a position, and enter the fray." --Michael Quinn Patton, Author of Utilization-Focused Evaluation, 4e "I found this text to be very interesting and useful in capturing and presenting varying perspectives in the field.
