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…

This study synthesized research on teacher efficacy. A 14-stage model was implemented to identify and analyze characteristics found in the synthesis population of 89 primary studies which addressed teacher efficacy. The 89 primary studies yielded 789 distinct and 973 total research hypotheses; 25 distinct and 973 total teacher efficacy constructs;…

This Bulletin describes the strength and duration of changeable risk and protective factors for youth violence at points in youth development when they appear most salient. These predictors are potential targets for prevention and intervention. The quantitative results of a large number of studies were synthesized using meta-analysis procedures.…

Although there are three main computer-assisted instruction (CAI) formats (drill and practice, simulation, and tutorial), tutorial format is particularly suitable to conceptual school subjects because this format: (1) explains the concept of the text; (2) tests the understanding of the topic; and (3) selects the next step of the subject. When a…

This digest addresses the role of evaluation and its basic logic, and provides a description of how the field is structured. In order to reach evaluative conclusions it is usually necessary to establish or identify factual promises and value premises. To obtain the required kind of overall evaluative conclusion, it is typically necessary to…

Talk remains by far the most used medium of instruction and classroom action. Classroom talk is typically dominated by triadic dialogue or an I-R-E (Initiate-Response-Evaluation) pattern of talk noted in the literature as consistent across grades and subjects. Studies seem to indicate that teachers utilize traditional forms of talk, even though…

Uses meta-analysis on teaching strategies research in science and finds that the so-called alternative science teaching strategies are more effective than traditional science teaching strategies. Shows that inquiry-oriented instruction characterizes the alternative strategies and distinguishes them from traditional science teaching strategies. (SR)

This meta-analysis synthesized results from test anxiety reduction programs. The treatment of test anxiety has been quite successful in reducing the test anxiety level of clients. The most effective treatments appear to be those that combine skill-focused approaches with behavior or cognitive approaches. Individually conducted programs, along with…

Considers the effects of learner control in computer-assisted instruction based on literature reviews and a meta analysis of 24 studies. Results suggest that learner control has little if any effect on students, and further research is recommended. (Author/LRW)

This article presents results of a meta-analysis of 58 studies of mathematics intervention for elementary students with special needs. Studies in preparatory mathematics, basic skills, and problem solving were reviewed. Duration and method of instruction proved important. Direct instruction and self-instruction were more effective than mediated…
