Engagement is one of the most widely misused and overgeneralized constructs found in the educational, learning, instructional, and psychological sciences. The articles in this special issue represent a wide range of traditions and highlight several key conceptual, theoretical, methodological, and analytical issues related to defining and measuring…

Schools and school systems throughout the nation are increasingly experimenting with using various instructional technologies to improve productivity and decrease costs, but evidence on both the effectiveness and the costs of education technology is limited. A recent report published by the Thomas B. Fordham Institute sets out to describe "the…

This article summarizes critical evaluation needs, challenges, and lessons learned in translational research. Evaluation can play a key role in enhancing successful application of research-based programs and tools as well as informing program refinement and future research. Discussion centers on what is unique about evaluating programs and…

The author argues that one of the worst aspects of logical positivism is its attempt to construct a value-free science and to exclude values from the scientific process. (Author/PN)

When participants with varied background and interests join in a collaborative activity, their different viewpoints may make the evaluation of the activity more difficult. Experience evaluating a multidisciplinary biomedical research center illustrates the influence of values on program evaluation. (Author/GDC)

Evaluations of special education interventions are different from research on medical interventions. Educational evaluations would be more useful if they applied an actuarial, or probability approach. Information should be collected over time and using various measures, thus increasing the available data. (GDC)

This paper reports the problems involved in measuring the extent to which the practice in program sites matches model theory formulated in Head Start Planned Variation. The main focus in studying program implementation is the question of internal validity, whether the children in the HSPV programs actually receive the treatment being evaluated.…

Because research synthesis enables one to determine either the overall effectiveness of a particular treatment or the relative effectiveness of different types of treatments, it is becoming increasingly popular as a tool in program evaluation. Numerous methodological problems arise, however, when research synthesis is applied to studies conducted…

This paper reviews two areas of limitations concerning college outcome assessments and argues that while cognitive outcomes may be effectively measured during the students' academic careers, the perceptions of alumni are a necessary component of the assessment of affective outcomes. The limitations that are addressed concern first, determining…

A number of issues involved in the large-scale assessment of science and mathematics education were illustrated during the conduct of two national surveys: the 1977 National Survey of Science, Mathematics, and Social Studies Education and the 1985 National Survey, Science and Mathematics Education. Development of the survey questionnaires started…

A model for research and evaluation in outdoor education is presented in this paper which includes a bibliography of representative research in outdoor, experiential education. The model stresses close interaction between program designers and evaluators and rests on the premise that the strength of outdoor education--interaction between people,…
