The authors cite problems but regard meta-analysis as an improvement over traditional methods of research integration. Advantages are increased objectivity, freedom from arbitrary levels of statistical significance, and potential to relate an array of independent variables to effect size. Disadvantages include questionable reliability of ratings…

Some of the advantages of meta-analysis as a useful approach to synthesizing research studies are described, along with caveats that a careful analyst should consider when applying this approach to research data. (LC)

Recommends that analysts (1) use conventional meta-analytic statistics when testing for moderator variables; (2) perform tests between mean effect sizes; and (3) continue to perform model tests in meta-analyses for which study outcomes are already consistent if they have theoretical expectations about moderators. (RS)

Argues that historians have often neglected ideological forces that have shaped their work. Offers a meta-analysis of the ideological dimensions of historical scholarship. Proposes a social psychoanalytical approach to history. Argues that a recognition of the connection between past and present would expose the ties between history and politics.…

This article proposes a set of criteria for reporting meta-analyses of topics in learning disabilities. Application of the criteria to examples of published meta-analyses reveals the wide variation in amount of reported data, which could influence the summative results of meta-analyses and subsequent judgment of face validity. (Author/DB)

Maintains that authors' meta-analytic findings make early competence accounts of theory of mind increasingly unlikely. Asserts that findings argue against executive function expression accounts, including that advocated by Scholl and Leslie (PS532407). Explains that meta-analytic findings directly contradict Scholl and Leslie's predictions…

Gene V. Glass is presently Regents' Professor of both Educational Leadership and Policy Studies and Psychology in Education at Arizona State University. He won the Palmer O. Johnson Award for best article in the "American Educational Research Journal" in both 1968 and 1970. Dr. Glass has also served on the editorial boards of 13 journals and has…

In their meta-analysis of clinical versus statistical prediction models, Aegisdottir et al. (this issue) extended previous findings of statistical-method superiority across such variables as clinicians' experience and familiarity with data. In this reaction, the authors are particularly interested in violence prediction, which yields the greatest…

Historically, cognitive-developmental and behavior-analytic approaches to the study of human behavior change and development have been presented as incompatible alternative theoretical and methodological perspectives. This presumed incompatibility has been understood as arising from divergent sets of metatheoretical assumptions that take the form…

This paper provides a summary of cost-benefit and cost-effectiveness analyses and their potential importance for decision making. The extent to which these tools are actually used, the possible connections between meta-analysis and cost-effective analysis, and the connection between effect sizes and benefit-cost ratios are discussed. (JAZ)

This article describes conceptual and methodological limitations of existing research on the efficacy of early intervention programs. Recent studies using meta-analytic techniques to generate testable hypotheses are reviewed. Recommendations for greater precision in measurement and for improved research design are offered. (DB)

Critiques K. Kavale's meta-analysis, which reported reliable significant correlations between auditory-perceptual skills and reading achievement. Concludes that Kavale fails to provide evidence that teaching auditory-perceptual skills is useful to learning disabled children unless skills are functional reading skills. (Author/CL)

The article critiques a 1987 (Kavale and Forness) meta-analysis which concluded that research does not support modality-based instruction. The study is faulted for its selection criteria as well as its failure to consider demographic differences, achievement level differences, multiplicity of preferences, definitions of terms, effect-size…

This response to Dunn (EC 221 793) reaffirms the conclusions of a meta analysis on modality-based instruction, through elaboration of the study's selection criteria and methodological factors. Although modality-based instruction is seen to be intuitively appealing, educators are encouraged, instead, to apply instructional methods of proven…

R. T. Ogawa and B. Malen's article does not meet its own recommended standards for rigorous testing and presentation of its own conclusions. Use of the exploratory case study to analyze multivocal literatures is not supported, and the claim of grounded theory to analyze multivocal literatures may be stronger. (SLD)
