Our third article on the history of evaluation use affirms its importance in evaluation practice and related literature. It first highlights the centrality of use in the field's professionalizing documents, extant theories, and the persistence of continuing research. Next, it discusses the challenge of evaluation theories in general, including the…

The act of valuing in an evaluation may be perceived in different ways. We consider the multiple theoretic perspectives that govern an evaluator's behavior and present a typology of evaluator valuing roles. Within this typology we describe three ways in which value judgments are typically reached--by stakeholders alone, stakeholders and evaluators…

Provides a synthesis of the critical commentary of each of the contributors to this volume. The field is a long way from a descriptive theory of evaluation, but small, well-defined steps that might be taken are outlined. (SLD)

This is an introduction to the six following articles, which discuss three people's views of evaluation in the perspective of "The New Rhetoric: A Treatise on Argumentation" by Perelman and Olbrechts-Tyteca, a book that contrasts argument and persuasion with reason and reasoning. (See TM 504 631-636). (CTM)

Classification or category systems are important for defining and introducing new concepts, such as decision management/facilitative v judgmental evaluations. Furthermore, category systems can lead to a reexamination or restatement of views of evaluation. (CP)

This essay discusses principles which govern evaluation theorizing, describing theorizing as a subjective, informal, and dynamic process. The papers of Rippey, Guba, and Wolf are used to illustrate the process of theory development, with special reference to evaluation as rhetoric. (See TM 504 630-635). (CTM)

The theorists whose work appears in this issue have confronted the exercise presented to them in vastly different ways. The editors of this journal asked these theorists to consider how they would evaluate the Bunche-Da Vinci program, and to make and specify assumptions about the program context. The primary task, however, was to describe "a…

Authors described various theories and methods of evaluation, as well as issues of procedure. (Editor /RK)

Program theory plays a prominent role in many evaluations, not only in theory-driven evaluations. This paper presents a case study of the process of developing and refining a program's theory within a user-oriented evaluation. In user-oriented (or utilization-focused) evaluations, primary users can play a role in defining their own program theory.…

Theorizing about evaluation should be conceptualized as a human activity governed by certain strategies and principles. The theories advanced by various evaluators have changed over the years, thus illustrating ten principles of evaluation. The starting point for theory development or modification is self-reflection and review of one's own…
