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…

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…

Chinese students often outperform U.S. students on international tests in mathematics. Chinese students' mathematics performances are assumed to be related directly to their teachers' deep mathematics understanding and ability to represent concepts flexibly in their classrooms, which, in turn, are thought to be influenced by Chinese mathematics…

Random samples of 50 articles each from the education and health-sciences literature are used to compare uses of quantitative evidence. Study designs and approaches in these fields are similar; thus no support is provided for the idea that educational research is less rigorous than that of the health sciences. (SLD)

Argues that international assessments that show U.S. educational inferiority are unwarranted, reviews the history of these assessments, and evaluates the major explanations of the achievement differences. It also examines the theoretical and empirical underpinnings of curriculum-centered explanations because of their relevance to school reform.…

Examines the current rift in perspective between whole language arts and traditional language arts instruction by analyzing the basis of each view in research and theory. Suggests research developments that might alleviate the present impasse. Describes the need for new hypotheses, a variety of designs, improved instrumentation, and collaborative…

Identifies important criteria for assessing the quality of educational research and applies these 20 identified criteria to 2 recent international comparative studies in education, the Second International Science Study and the first International Assessment of Educational Progress. The major types of criteria are utility, propriety, and accuracy.…
