Methodological reviews have been used successfully to identify research trends and improve research practice in a variety of academic fields. Although there have been three methodological reviews of the emerging field of computer science education research, they lacked reliability or generalizability. Therefore, because of the capacity for a…

The article reviews the current status (1993-2007) of psychosocial treatments for children and adolescents who have been exposed to traumatic events. Twenty-one treatment studies are evaluated using criteria from Nathan and Gorman (2002) along a continuum of methodological rigor ranging from Type 1 to Type 6. All studies were, at a minimum, robust…

Whether or not there are sex differences in helping behavior is a question that has attracted interest from both theoretical and applied perspectives. A meta-analysis was conducted of 172 studies of helping behavior, coded for publication date, source, sex of author, sample size, setting, type of appeal for help, availability of other helpers, sex…

Discusses results of a meta-analysis which sought to identify those variables found in research as strongly correlated with responsible environmental behavior. Variables found significant were: knowledge of issues; knowledge of action strategies; locus of control; attitudes; verbal commitment; and sense of responsibility. Proposes a model of…

Meta-analysis is a technique for combining the summary statistics from previously conducted research studies to indicate the direction of results and provide an index of the magnitude of effect size. This paper focuses on the effect of the violation of the assumption of independence (that the value of any included statistic is in no way…

Drawing from work on the meta-analysis of over 500 validation studies of the General Aptitude Test Battery (GATB) by the U.S. Employment Service, the paper presents a methodological message and a substantive message. Gene Glass's methods, as used by Edwin Ghiselli in personnel selection, ignore study artifacts (sampling error, error of…

Addresses the implicit assumption that instructional media represent meaningful experimental variables independent of instructional content or strategy. Results of computer-based instruction (CBI) studies (both well-designed and flawed) and meta-analyses are reviewed to support the authors' position that this assumption is invalid, and new…

Educational programs and evaluations which were submitted to the Department of Education's Joint Dissemination Review Panel (JDRP), in order to be named validated programs, were studied to identify program characteristics associated with large versus small effect size. Effect size was calculated for 165 out of 232 submittals reviewed by JDRP from…

This meta analysis of 101 studies of computer-based education in colleges highlights examination performance, student attitudes toward instruction and computers, the relationship of publication source to study outcome, and time needed for instruction. One hundred twenty-one references are listed. (Author/LRW)

A meta-analysis was conducted of 137 studies investigating the effects of father absence due to employment, military service, death, divorce, separation, or desertion on children's cognitive performance as assessed by scores on standardized intelligence, scholastic aptitude, and academic achievement tests and school grades. Aggregation of the…

A meta analysis was conducted of studies of college students' evaluations of their teachers. Forty-seven studies were included, representing 74 multisection courses, in which four selection criteria were met. An actual, rather than an experimental class was used; the unit of analysis was the class rather than the individual student; a common…
