"Evaluation Roots: Tracing Theorists' Views and Influences examines current evaluation theories and traces their evaluation within the framework of theories, building upon theories and how evaluation theories are related to each other. Initially, all evaluation was derived from social science research methodology and accountability concerns. The way in which these evaluation roots grew to form a tree helps to provide a better understanding of evaluation theory. Thus, the book uses an evaluation theory tree as its central metaphor." "This book is intended for graduate students in departments of education, psychology, sociology, management, public policy, public health, and any department with a course in evaluation theory. It will also prove invaluable to professional evaluators and applied researchers who are seeking clarification on the differences between theoretical approaches to evaluation and how they developed."--BOOK JACKET.
