Poor program implementation constitutes one explanation for null results in trials of educational interventions. For this reason, researchers often collect data about implementation fidelity when conducting such trials. In this article, we document whether and how researchers report and measure program fidelity in recent cluster-randomized trials.…

Education decision makers routinely make choices among programs and strategies to implement. Policy demands increasingly require that such decisions are based on evidence regarding program effectiveness at improving student outcomes. However, research evidence is but one of the considerations that practitioners must juggle, along with local…

Commentaries regarding appropriate methods for researching professional development have been a frequent topic in recent issues of "Educational Researcher" as well as other venues. In this article, the authors extend this discussion by observing that randomized trials of specific professional development programs have not enhanced our…

Impact evaluation plays a critical role in determining whether federally funded research programs in science, technology, engineering, and mathematics are wise investments. This paper develops quantitative methods for program evaluation and applies this approach to a flagship National Science Foundation-funded education research program, Research…

Traditional methods for preparing systematic reviews and syntheses of effectiveness studies rely on a limited set of methodological criteria to include studies that measure and report effects too narrowly to forward the mission of evidence-based practice. This article discusses why and how the criteria for study selection, evidence screening, and…

A strong base of research is needed to guide investments in teacher professional development (PD). This article considers the status of research on PD and articulates a particular direction for future work. Little is known about whether PD can have a positive impact on achievement when a program is delivered across a range of typical settings and…

The most important impact of the Baseline study on vocational education has been on the Congress. Recommendations in the Baseline reports have been written into the vocational education provisions of various pieces of federal educational legislation. (Author/AM)

Explores issues in evaluating exemplary programs, including the measurement of the degree to which the program is exemplary or promising. Suggests that comparison (control) group analysis can mislead researchers about the effectiveness of a program and suggests the use of gain scores to identify exemplary programs. (SLD)

Nearly 20 educational models were studied in an effort to determine varying patterns of effects of educational programs in different settings. Children's academic achievement was measured from kindergarten through third grade in each model program. The study's design, methodology, and findings are reported in this article. (GC)

Notes that even with the problems identified in this paper, consistent, positive results are appearing in preliminary reports. Equally important, the data seem to support a number of reasonable notions about the impact of distinctive curricula on students. (Author/AM)

Six deficits of this model are discussed: disparity in proponent prowess, fallible arbiters, excessive confidence in the model's potency, difficulties in framing the proposition in a manner amenable to adversary resolution, "a cat's-paw for biased decision makers," and, excessive costs. (Author/JM)

Education researchers, practitioners, and policymakers alike are committed to identifying interventions that teach students more effectively. Increased emphasis on evaluation and accountability has increased desire for sound evaluations of these interventions; and at the same time, school-level data have become increasingly available. This article…

Reviews some current criticisms of teacher education and the nature of recent reform proposals. Presents a series of propositions dealing with (1) potential reform of teacher education's substance and process and (2) governance of certification, accreditation, and the link between research community and teacher education process. (CMG)

Discusses the use of transaction-cost economics in measuring the impact of educational reforms and whether these reforms are likely to succeed in the "real life" of schools. Several current educational reforms are judged on the basis of their transaction costs and consequent prospects for success. (GR)

The author responds to Pinnell et al's (1996) call for caution in using cost-benefit analysis in measuring educational reform success. It is argued that reform already is being sold to state legislators and educators in cost-benefit terms and that research has been inappropriately used in the selling process. (GR)
