Discusses the research design for the Third International Mathematics and Science Study (TIMSS) of the International Association for the Evaluation of Educational Achievement (IEA). Asserts that the TIMSS is a compromise between longitudinal and cross-sectional survey designs and will yield more information about student achievement. (CFR)

Considers how sociohistorical context affects procedures by which sociologists obtain subject permission for interviews and audiotaping interviews. Reviews a 1950s study involving interviews with institutionalized, schizophrenic women contrasting ethical and institutional implications of informed consent in that context to contemporary informed…

The results of an in-depth analysis of the lab activities found in two popular high school biology textbooks are presented. Activities were rated against 24 task categories that parallel skills or behaviors which reflect scientific inquiry, problem-solving skills, manipulative skills, and observational skills.

Statistical methods for program evaluation with nonexperimental data are reviewed with emphasis on circumstances in which nonexperimental data are valid. Three solutions are proposed for problems of selection bias, and implications for evaluation design and data collection and analysis are discussed. (SLD)

Dismissing research that is not theory driven, hypothesis testing, or generalization producing does injustice to the variety of contributions that qualitative research can make. Studies conducted through qualitative approaches are reviewed to summarize the desirable outcomes that can result. No research model has a monopoly on quality. (SLD)

This commentary argues that the study reported in EC 605 442, which indicated long-term gains for children with autism who experienced intensive behavioral intervention as preschoolers, needs to be replicated to be convincing, especially given the problem of nonrandom assignment of experimental and control groups.

This review offers a general theory of utilization of educational evaluation and considers factors affecting utilization, including evaluation context factors and evaluator-controlled factors. Special challenges in evaluating programs for gifted students and design shortcomings common in evaluation of such programs are identified. Specific…

Finds that introductory psychology textbooks present limited and often confusing coverage of research methods. Presents two research models that delineate separate dimensions for data collection procedures, research designs, and research settings. Contends that these models provide better coverage of research strategies. Includes suggestions for…

The application of time series analysis is described, focusing on the use of regression analysis for analyzing time series in a way that may make it more readily available to an evaluation practice audience. Practical guidelines are suggested for decision makers in government, health, and social welfare agencies. (SLD)

Presents two statistical topics and examples of their use in natural resource monitoring. The first topic deals with use of correlated observations in calculations of variance estimates for a regional mean, required sample size determination, and confidence intervals. The second topic concerns the use of Bayesian techniques in hypothesis testing.…

Outlines 13 priority research topics and 51 important research questions concerning medical education in ambulatory care settings, as defined by a distinguished group of medical educators, clinicians, and policymakers.

Examines the existing research on multiculturalism in general teacher education and special education teacher preparation programs. Results find that a significant degree of research on multicultural teacher education has been narrow in scope and has utilized a pre/post test design to measure student growth. (Author/CR)

A review of 20 research studies on the use of constant time delay in teaching chained tasks is analyzed in regard to demographic variables (participants, settings), procedural variables (probe format, delay sessions), outcome measures (effectiveness, generalization), and methodological adequacy (dependent and independent variable reliability).
