A 3-year research project (1974-77) in connection with the national campaign against adult illiteracy involves assessing the role of broadcasting in motivating adults to ask for help, investigating appropriate instructional media, and correlating the various learning situations and the subsequent social benefits. Some problems of research design…

"No significant differences" is the most frequently quoted conclusion of surveys comparing the effectiveness of alternative instructional technologies. While this effectiveness conclusion does not differ for the research reported here, the other purposes are to discuss alternative criteria for measuring effectiveness and to analyze potential…

The adverse impact of a content-valid job sample test of metal trades skills was compared to that of a well-constructed content-valid written achievement test for the same technical area. The adverse impact of the former was considerably less. Suggests that industrial psychologists should explore more fully the potential of performance testing.…

Explores some of the methodological issues and problems involved in studies of black mother-child interactions, and presents alternatives to previously-used methods of selecting tasks, instructing subjects, and collecting data in the home. (BD)

Discusses a few examples of areas in which 'we-they' dichotomizing is manifested in classrooms and which could be documented and analyzed through qualitative research. Concludes that studies that yielded concrete classroom examples could help teachers shift towards broader, more realistic, and more positive role definitions than are typical.…

Reviews experimental studies of behavioral consequences of exposure to violent or aggressive pornography and evaluates the validity and relevance as support for censoring pornography in the aftermath of the Meese Commission.

Maintains that before teachers or administrators become involved in classroom research they should carefully assess the conceptual soundness, feasibility, and ethics of any proposed study. Also considered should be ways to facilitate research and the potential rewards of research involvement. (BB)

Two quasi-experimental longitudinal studies, conducted by the Centre for Educational Research in Landau, Germany, are reported. Various effects of reporting the outcomes of learning to students were studied. Results emphasized the importance of feedback for learning outcomes. (LMO)

Responds to commentaries by Bereiter and Gersten concerning findings of the High/Scope Educational Research Foundation's 15-year Preschool Curriculum Comparison Study. Addresses issues of design of study, experimenter bias, sample size, self-report validity, interpretation of findings, and related topics. (NH)

To facilitate meta-analysis of diverse study findings, a mixed linear model with fixed random effects is presented and illustrated with data from teacher expectancy experiments. The standardized effect size is viewed as random and the variation among effect sizes is modeled as a function of study characteristics. (Author/BS).

Describes experiments relating information to decision making. The experiments were developed to validate previously suggested conceptual model of information flow and its relation to decision making and to establish specific values for significant parameters involved. Background and summary of recent research and experimental design and research…

A meta analysis of research on children's attributions for success and failure was conducted to test the adequacy of the egotistic bias hypothesis for children in grades one to seven. Results supported the egotism hypothesis and indicated that both question wording and research context are important determinants of children's attributions.…

Given the increased data-based capabilities of educational institutions, educational researchers should have more opportunities to use sequential designs. This paper illustrates how to analyze educational data from a cohort-sequential design. University data pertaining to grade inflation were analyzed using a variant of multiple regression.…

The appropriateness of within-course time series analyses for instructor ratings and the potency of inducing rater perceptions of the rating process as an interactive variable in course evaluations were assessed. A specific positive psychological set prior to evaluation tended to produce more favorable evaluations than general, brief instructions.…
