The literature describing deaf persons' intelligence was subjected to a quantitative and qualitative review in this analysis of 85 studies containing independent samples of 43,177 deaf subjects. First, bibliometric analyses were conducted to define the scope, dissemination, and trajectory of the research investigating deafness and Intelligence…

Concern over the validity of statistical tests performed on data that may not satisfy underlying assumptions has prompted methodological researchers to perform Monte Carlo studies for frequently used tests. Unfortunately, these studies appear to have had little impact on methodological practice. One reason is the lack of an overarching framework…

Study effect meta-analysis was used to synthesize the results of explicit instruction on critical thinking (CT). The approach involved the collection of 250 studies (books, articles, dissertations, and abstracts) from the ERIC database and "Dissertation Abstracts International", coding of the study features, calculation of effect sizes,…

Since about 1962, researchers have explored the effectiveness of educational software in the schools under various conditions, and many have concluded that computer assisted instruction (CAI) is effective. Many of the studies reviewed to support this conclusion, however, had design flaws. Reviews of educational software effectiveness studies have…

Differences in science achievement between males and females have been examined either directly or indirectly in a variety of studies. This investigation reviewed a quantitative synthesis of correlational research on science affect, ability, and achievement conducted by Steinkamp and Maehr. Their findings were reassessed by employing a…

A synthesis of findings from 38 studies on group-based applications of mastery learning strategies are presented. Meta-analytic procedures were used to combine the results of the studies and to calculate overall estimates of the effects of group-based applications. Results show that such applications yield consistently positive effects on both…

The meta-analytic approach used in this review is similar to that described by Glass et al. (1981), whose approach requires a reviewer to locate and code studies of an issue, to code study outcomes on a common scale, and to use statistical methods to relate study features to outcomes. The studies considered for use in this meta-analysis came from…

"The purpose of this article is to report a review of the developing empirical literature to explain "expert" teacher behavior, by analogy, from the cognitive psychology expertise literature. Emphasized is a review of the expert-novice cognitive psychology literature, encompassing the research on: chess, and other games; physics,…

Intended for researchers, policy analysts, and practitioners, the book provides a review of 176 documents (both published and unpublished) focusing on education, employment, and independent living outcomes across ten handicapping conditions. The first chapter provides an introduction to the project to review the extant literature on the subject.…

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…

Meta-analytic techniques were used to analyze the effects of age, education, and work experience on General Aptitude Test Battery (GATB) validities and test scores. The sample consisted of 30,568 subjects from 143 Specific Aptitude Test Battery (SATB) validation or revalidation studies analyzed since 1972. The effect of these three variables on…

The relatively simple question of whether sex differences exist has evolved into the more theoretically interesting question of why sex differences occur. This transition has come about because of the meta-analytic investigations of sex differences in social behavior which established sex difference trends in a variety of social behaviors. Many…

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…

This monograph includes chapters on: (1) The Need for Educational Productivity Research; (2) Syntheses of Research on Factors Influencing Learning; (3) Contextual and Transactional Influences on Science Outcomes; (4) Identifying the Salient Facets of a Model of Student Learning: A Synthesis of Meta-Analysis; and (5) Use of National Survey Data in…
