Describes an approach to overcoming challenges of large-scale multisite educational reform evaluation in the context of a study of the relationships between student achievement and instructional practices in the National Science Foundation's Systemic Initiatives program. Pooled data from 11 sites were analyzed with a planned meta-analytic…

Submitted the Myers-Briggs Type Indicator (MBTI) to a descriptive reliability generalization analysis to characterize the variability of measurement error in MBTI scores across administrations. In general the MBTI and its scales yielded scores with strong internal consistency and test-retest reliability estimates. (SLD)

This paper synthesizes the findings of social skills interventions conducted with 3- to 5-year-old children with disabilities between 1975 and 1999. Provided are study purposes, procedures, measures, and findings as well as analysis of effect size outcomes. Positive outcomes were associated with a range of interventions, including modeling,…

Used meta analytic methods to summarize results of Monte Carlo studies of test size and power of the F test in the single-factor, fixed-effects analysis of covariance model, updating and extending narrative reviews of this literature. (SLD)

Presents a methodological critique of the 1998 meta-analysis of child sexual abuse outcomes by Rind et al. By restricting a supposedly broad meta-analysis to only some of the population in question, the conclusions they drew regarding this complex topic, primarily that adult-child sex is not necessarily harmful, are invalid. (Contains 33…

Presents a review of all types of child sexual abuse research ignored by Rind, Tromovitch, and Bauserman in their 1998 meta-analytic study. Eight major findings are addressed. Altogether these findings demonstrate the narrow focus of the meta-analysis. By restricting a broad meta-analysis to only some of the research and population in question,…

The meta-analytic method proposed by S. W. Raudenbush (1988) for studying variance heterogeneity was studied. Results of a Monte Carlo study indicate that the Type I error rate of the test is sensitive to even modestly platykurtic score distributions and to the ratio of study sample size to the number of studies.

Review of 1,791 cases from 8 studies of college business students' learning styles revealed small to moderate effect sizes in style preferences. Kolb's learning styles were not evenly distributed and there was much diversity among business students and within specific majors. (Contains 22 references.) (SK)

Studies (N=25) of the effectiveness of Direct Instruction programs with special education students were examined in a meta-analysis comparison. None of the studies showed results favoring comparison groups. Fifty-three percent of the outcomes significantly favored Direct Instruction. Effects were not restricted to particular handicapping…

The critical analysis of 23 studies using respondent techniques for the reduction of excessive emotional reactions in school children focuses on research design, dependent variables, independent variables, component analysis, and demonstrations of generalization and maintenance. Results indicate widespread methodological flaws that limit the…

A grounded meta-analytic technique for comparing organizational interventions derived from rational-based strategies (e.g., management-by-objectives, planned change) with organizational culture-based strategies (organizational culture, climate) is described. The method is seen as useful for integrating qualitative and quantitative research.…

Employed meta-analysis to determine existence of the detrimental effects of extrinsic rewards on intrinsic motivation. Results showed that within strictly defined parameters the phenomenon concerning the detrimental effects of reward described in Deci's Cognitive Evaluation Theory did exist. (Author/NB)

A critical analysis of 13 validation studies of the use of peer nomination forms to identify gifted students indicates methodological weaknesses. A four-step plan for research on the psychometric qualities of peer nomination forms is proposed. (Author/DB)

Meta analysis of 273 investigations concerned with the modification of attitudes toward persons with disabilities revealed equivocal results possibly due to methodological deficiencies (study quality ratings were low) or to the complexity of human attitudes. (Author/DB)

Examines by meta-analysis the effect that exposure to pornography produces on aggressive behavior under laboratory conditions considering a variety of possible moderating conditions. Demonstrates a homogeneous set of results showing that pictorial nudity reduces subsequent violent behavior, but that depictions of nonviolent sexual behavior and…
