In a reflective commentary, the authors address the implications of the fact that, in action settings, implementation and evaluation are often carried on by the same person, and they raise the question, "Should evaluation become implementation?" (PN)

Stakeholder-based studies modify the relationship between evaluator and user, producing conflict that can cause evaluators to regress to familiar, traditional patterns that leave interactive evaluation strategies only partially implemented. (Author/PN)

Program theory and implementation process theory contribute, respectively, to specifying the what and the why of program delivery. This article discusses the relationship between these two theories and the types of data collection methods that can be derived from each in order to contribute to more comprehensive evaluation designs. (JAZ)

A short history of program theory in evaluation is reviewed. Two related problems in program evaluation are discussed and illustrated: (1) how to specify in measurable terms the consensus of theories and values that guides the program; and (2) how to construct a theoretical framework that specifies the use of these measurements. (Author/JAZ)

The evaluators of Push/Excel assumed that it was a systematically developed program with measurable outcomes, not a charismatically inspired movement whose effects would be hard to pin down. As a result, neither the program nor the evaluation approach used were adequately tested. (Author)

Six essays are presented that discuss the definition, methodologies, and contexts of program environment evaluation. Specific topics covered include the use of profiles and models, social-psychological classroom environments, program/organization congruence, program personnel, and measuring implementation of social treatment.

The Bureau of Evaluation, created by the Louisiana Department of Education, has established policies and procedures that ensure use of evaluation findings by both policymakers and program administrators. Information on its development, structure, mission, rationale, staffing, and operations is provided. (PN)

The 9 articles of this theme issue stem from a project on alcohol and drug abuse that involved 14 projects, 10 of which began with randomized clinical trials. These papers describe implementation problems associated with experimentation in field research and the focus on ensuring internal validity. (SLD)

The organization and operations of an evaluation unit in a local governmental agency are presented. How local evaluation units manage (1) external relations (to obtain funding, to gain access to data sources, and encourage evaluation use) and (2) internal operations (including staffing, communication, data collection, and analysis) are described.…
