The purpose of this study was to determine the types of research methods used to study cognitive processing development in gifted learners, from 1975-1986. Of 870 research publications identified on giftedness, 522 publications (60 percent) dealt with cognitive processing development. Research designs used most frequently were causal-comparative,…

This paper contains summaries of the findings of research and meta analyses conducted on the effectiveness of computer-based instruction (CBI) on student achievement. Eight conclusions, based on the CBI research are then given: (1) when CBI and traditional instruction are compared, students receiving CBI demonstrate equal or better achievement;…

Meta-analysis techniques were used to determine whether or not there are differences in General Aptitude Test Battery (GATB) validity and test scores between samples from the Northern, Southern, and Western United States census areas. The sample consisted of 26,111 subjects from 122 validation studies of the Specific Aptitude Test Battery (SATB).…

The usefulness of taking notes to enhance recall was assessed, based on reviewing the research literature using the techniques of meta-analysis. Meta-analysis allows for both the computation of the strength of an effect within studies and the determination of mean effect sizes averaged across related studies. Fourteen studies that maintained…

This article finds the empirical review of the intellectual effects of family factors by Lala Carr Steelman wanting because (1) it is selective and incomplete; (2) it ignores systematic aggregate effects; (3) it imposes linear analysis on nonmonotone relationships; and (4) it disregards most of the confounds identified by Steelman as crucial.…

The author responds to criticism by R. B. Zajonc on a review of the extant literature on the intellectual consequences of sibship size and birth order. (Author/LMO)

A synthesis of findings from 46 studies on group-based applications of mastery learning strategies points out their positive effects on both cognitive and affective student learning outcomes as well as on several teacher variables. Variables affecting the success of mastery learning, such as choice of strategy, student grade level, and study…

A meta analysis of thirteen published studies on computer-based instruction (CBI) reported positive effects on learning. In twelve studies, components of effective CBI which parallel components of effective teaching included: (1) attention and motivation; (2) presentation and opportunities to practice, elaborate, and problem solve; and (3)…

nter arguments are presented to defend the author's data selection practices and to point out pitfalls in Baker's critique. (SLD)

This article extends both the logic and the statistical procedures used in a recent analysis of Hyde's data on gender differences in cognitive abilities by Rosenthal and Rubin. The logic of a "model fitting" approach to meta-analysis is described. Relevant statistical procedures and goodness-of-fit tests are illustrated. (Author/BS)

The aggregate findings of experiments with modern mathematics for the last 30 years show that there have not been many detrimental effects of "new math" either on achievement or attitude. Instead, the evidence points toward beneficial effects in terms of improvement in overall achievement and attitude. (Author/BW)

This article is a response to Ruth Wade's meta-analysis of inservice teacher education research in the same issue of "Educational Leadership" (EA 518 308). Factors making a difference in inservice education are identified, but more work needs to be done in understanding the specific, practical details, allowing application. (DCS)

This synthesis of findings from 40 studies showed that students can raise their test scores by taking practice tests. The size of the gains were a function of three factors: identical vs. parallel forms of the test, number of practice tests, and ability level of the student. (Author/BW)

This article reports the results of a meta-analysis of 20 research articles containing 89 effect sizes related to the use of digital tools and learning environments to enhance literacy acquisition. Results (weighted effect size of 0.489) demonstrate that technology can have a positive effect on reading comprehension, but little research has…

A meta-analysis was conducted to evaluate the success of cognitive-behavioral therapy in reducing disruptive behaviors exhibited by school-age children in a school setting. Twenty-seven articles about studies using cognitive-behavioral therapy and a teacher measure of disruptive behavior were analyzed critically, and appropriate outcome measures…
