A review of studies published between 1980 and 2005 shows a significant positive effect of specialized training on the competency of caregivers in childcare (d=0.45, S.E.=0.10). Experimental results from the meta-analysis were significantly smaller for settings with no fixed curriculum content, delivery of the training at multiple sites and…

Person-centered education is a counseling-originated, educational psychology model, overripe for meta-analysis, that posits that positive teacher-student relationships are associated with optimal, holistic learning. It includes classical, humanistic education and today's constructivist learner-centered model. The author reviewed about 1,000…

Study Purpose: This article examines the influence of "Educational Administration Quarterly (EAQ)" on the scholarly literature in education during the 25-year period 1979 to 2003. This article continues part of the first critique of EAQ conducted by Roald Campbell in 1979. Study Methods: Two citation measures are used in this study to assess EAQ…

Numerous studies show that children's language ability is related to false-belief understanding. However, there is considerable variation in the size of the correlation reported. Using data from 104 studies (N=8,891), this meta-analysis determines the strength of the relation in children under age 7 and examines moderators that may account for the…

The purpose of this synthesis is to summarize the effectiveness of peer-mediated interventions on the mathematics performance of both students with disabilities and those at risk for mathematics disabilities. Meta-analytic techniques were used to calculate mean effect sizes for 17 studies that met inclusion criteria. Results indicate that…

This paper provides a table that contains a summary of resources available that support the National High School Center's "Eight Elements of High School Improvement: A Mapping Framework". This framework is based on eight common elements of systemic school reform and provides a structure for understanding, aligning, and prioritizing…

There is a highly compelling case for using technology on a large scale to increase access to and improve America's adult education and workforce skills enterprise. By the reckoning of the National Commission on Adult Literacy and others, the nation must reach many more millions of adults with effective college- and job-readiness skills programs…

A meta-analysis was conducted on school-based interventions to reduce obesity in children. Sixty-six (k = 66, N = 31,059) comparisons from 40 published studies from 1997 through 2008 were included in analyses. Results indicated a significant effect for school-based interventions with an overall weighted effect size of r = 0.05. Several moderating…

S. Jackson and S. Jacobs' article entitled "Generalizing about Messages" represents an important methodological innovation in communication research. The article urges procedural change by recommending the use of multiple-message designs because of a weakness in single-message designs; it recommends analyzing message-replication data…

This work supplements a previous work, "Philosophical Aspects of Library Information Science in Retrospect." It explores Library Information Science, which deals with the facilitation of recorded knowledge, the metalibrarianship encompassing the theoretical aspects of a broad range of recorded communications, and the philosophies…

This paper summarizes the results of a quantitative review of the validity of the employment interview. It begins by discussing factors that make the interpretation of interview validity data difficult. The interpretation of interview validity data is shown to be hampered by the heterogeneity of constructs and measurement methods in the interview.…

One purpose for combining research studies is to estimate a population treatment effect. The internal validity of a model for how effect size estimates should be computed and combined will hinge upon the homogeneity of the effect size variation. Effect size variation may be assessed in the form of a summary fit statistic, and a direct…

This research describes the statistics and interpretations currently used for reporting discriminant analysis results and attempts to provide some approximate guidelines. Articles in the last 10 years of the American Educational Research Journal (AERT) were scanned. Eighteen studies containing 86 different discriminant analyses were identified and…

The article describes procedures employed for the quantitative synthesis of single-subject research literature in special education. The need for objective, systematic review procedures is noted; previous approaches are reviewed; and the authors' approach (which makes use of overlapping data across phases as an outcome metric) is outlined.…

An evaluation of the "Percentage of Nonoverlapping Data" approach for quantifying outcomes of single-subject research in special education reveals that it is potentially too sensitive to atypical baseline data, not powerful enough to discriminate important treatment differences, and adversely affected by even subtle trends in the data.…
