This paper presents a global approach to the media comparison literature. Beginning with the pros and cons of media research, it discusses the results of both individual and meta-analysis research, compares the different methods researchers have used to determine media selection, and concludes with the most recent trends in media selection. It is…

Conclusion about site-specific determinants of educational outcomes of the controversial longitudinal evaluation of the Follow Through programs (1976) are challenged again by reexamining the Direct Instruction model data. Reanalysis confirms earlier critiques and supports more recent research funding on the relationship between types of…

This Council on Library and Information Resources (CLIR) report summarizes and analyzes more than 200 recent research publications that focus on the use of electronic library resources (digital libraries and digital resources) and were published between 1995 and 2003. Eight major ongoing studies (each with multiple publications) are identified as…

Quantitative self-assessment studies that compared self-evaluations and teacher marks/grades were subjected to meta-analysis. Results of a meta-analysis of 51 studies are summarized. It is suggested that researchers should attend to both good design and to adequate reporting of self-assessment studies. (TJH)

Meta analysis techniques were used to synthesize research on teaching students how to control variables when designing an experiment. The review included 65 controlled studies. Findings are reported in terms of the influence on effect sizes of characteristics of the study, instruments used, treatments applied, and results' utilities. (SLD)

Meta-analysis of 143 effect sizes in 43 studies of adventure programming for adolescents found an overall effect size of 0.31. Summary effect sizes of outcome categories differed significantly among categories, however. Effect size was related to program length and participant age but not to delinquent status. Discusses the lack of pertinent…

This article provides an integrative review of prevention and intervention studies addressing dropout or school completion described in professional journals. Forty-five intervention studies were coded according to research design, participants, interventions, and outcomes to describe the range of data-based programs and approaches available in…

This article explores how the evidence base for aspects of early childhood has been explored using systematic research synthesis methods developed at the Evidence for Policy and Practice Information and Co-ordinating Centre (EPPI-Centre). Three early childhood systematic reviews have been carried out using EPPI-Centre procedures and tools. The…

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).

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.…

Separate meta-analyses have been completed recently on the effectiveness of computer-based education (CBE) in elementary schools, high schools, colleges, and nontraditional postsecondary institutions. Several conclusions can be drawn from these meta-analyses. First, although CBA has not been uniformly successful in all its guises and at all…

A meta-analysis of nine studies on psychotherapy with persons who have mental retardation found a wide range of research designs, types of interventions, and participants. The evaluation also pointed to a moderate degree of change in outcome measure and moderate effectiveness in terms of benefit to clients with mental retardation. (Contains…

Reviews, analyzes, and critically assesses a sample of articles reporting research findings related to the instructional effectiveness of computer-assisted instruction (CAI). Problems in CAI research are described, including validity of the experimental research design, and current trends in CAI research are discussed. (31 references) (LRW)

This article summarizes single-subject design intervention studies that include students with learning disabilities. Effect sizes of 85 studies were analyzed across instructional domains, sample characteristics, intervention parameters, and methodological procedures. Findings are supportive of the pervasive influence of cognitive strategy and…

Discusses logic and interpretation problems inherent in doing quantitative syntheses of single-case research. Addresses the meta-analytic method of using percentage of nonoverlapping data, highlighting special concerns related to withdrawal designs, sensitivity to variability in behavior, social significance of behavior change, and variables that…
