Provides an expanded analysis of rigor and relevance in the context of program evaluation. Epistemological rigor, epistemological relevance, methodological rigor, and methodological relevance are defined and illustrated in the literature on vocational education evaluation. (Author/SK)

Six case studies are discussed, which illustrate the experimental and pragmatic epistemological paradigms as they function independently, compete with one another, or complement each other. Researchers should consider not only the substantive goals of an evaluation, but also the epistemological goals. (SLD)

The eight articles of this issue examine the nature of differences that arise between qualitative and quantitative researchers in program evaluation in terms of goals and epistemologies. The origins of these differences and their consequences are explored. Authors represent both perspectives but do not defend their ideological turfs. (SLD)

Qualitative evaluation and quantitative evaluation are discussed, examining how the perspective of each can and should create a critical debate that encourages inquiry instead of hostility. To achieve the major goal of linking evaluation information to the organization's culture, the evaluator needs to use multiple methods in a responsive,…

Three studies are presented, which illustrate situations in which researchers and funders agreed on the primacy of either the experimental or pragmatic paradigms but acknowledged a role for the other.
