Evaluation theories can be tested in various ways. One approach, the experimental analogue study, is described and illustrated in this article. The approach is presented as a method worthy to use in the pursuit of what Alkin and others have called descriptive evaluation theory. Drawing on analogue studies conducted by the first author, we…

In this paper, the author argues that evaluation theory and practice interact insufficiently today, even though early evaluation theorists expected them to be closely intertwined. She views this limited connection as the result of differing interests on the part of theorists and practitioners, differing frequencies of dissemination, and differing…

In this article, I report on an exploratory study that examined evaluation practices in France. The research began with observations of practitioners' activities, with a particular focus on the phases of evaluation…
