This is the first comprehensive view of the work of scholars in several different disciplines contributing to the development of the psychology of science. This new field of inquiry is a systematic elaboration and application of psychological concepts and methods to clarify the nature of the scientific enterprise. While the psychology of science overlaps the philosophy, history, and sociology of science in important ways, its predominant focus is on individuals and small groups, rather than broad social institutions and concepts. The introduction surveys the field and traces its evolution in a historical context. Several contributors address epistemological issues raised by the psychology of science. Subsequent chapters discuss developments in the cognitive psychology of science, scientific theory, and the influence of social relationships on scientists' work. The conclusion proposes an agenda for further progress in this new approach to understanding science.

What methodological tools have been most useful in doing evaluation? What are some of the new methodologies that are being used and developed? Will the types of things evaluated expand from programs, personnel, and products to foreign aid, medical technology, environmental interventions, and World Bank loan programs? What will evaluation be like in the 21st century? These impressive evaluators from around the globe explore how evaluation has come to be what it is today and what the professional evaluation landscape will be like in the future. They examine the following:

-What makes evaluation different from other disciplines?

-The links and differences between evaluation and auditing professions?

-Which activities have priority in evaluation, under what circumstances, and for what purposes?

-New methodological approaches to doing evaluation.

-The issues of advocacy versus truth in evaluation and between evaluating programs versus empowering people to evaluate their own programs.

Evaluation for the 21st Century features thoughtfully written introductions to each of the main sections that provide a context and synthesis of the various evaluators? chapters. After reading this groundbreaking book, researchers and practitioners will be able to recognize these new developments in evaluation as they encounter them, place them in context, and incorporate them into their own evaluation professions and practices.

A stunning achievement, Evaluation for the 21st Century is for all professionals and practitioners in evaluation, management, public administration, sociology, psychology, education research, public health, and nursing.

Foundations of Program Evaluation heralds a thorough exploration of the field of program evaluation--looking back on its origins. By summarizing, comparing, and contrasting the work of seven major theorists of program evaluation, this book provides an important perspective on the current state of evaluation theory and provides suggestions for ways of improving its practice. Beginning in Chapter Two, the authors develop a conceptual framework to analyze how successfully each theory meets the specific criteria of its framework. Each subsequent chapter is devoted to the presentation of the theoretical and practical advice of a significant theorist--Michael Scriven, Donald Campbell, Carol Weiss, Joseph Wholey, Robert Stake, Lee Cronbach, and Peter Rossi.
