A meta-analysis of 79 studies of reading performance of low achievers with and without learning disabilities found students with the learning disabilities label performed considerably worse on reading measures. Use of timed tests greatly increased the difference in reading performance between underachievers and students with the learning…

Psychological consequences of presymptomatic DNA-testing for Huntington's disease are reviewed. Both carriers and noncarriers experience emotional reactions after disclosure of their test results; however, no long-term adverse emotional consequences have been revealed. Consequences for the family are discussed. Future research should include…

Meta-analysis of 16 studies of expatriate managers' adjustment and 25 of expatriate job performance showed that mean effect sizes were lower than in previous analyses. Cautions about basing cross-cultural training on results of such studies were expressed. (Contains 68 references.) (SK)

Explores implications for evaluation practice of using five different perspectives on organizations, drawing on the four models of social program implementation developed by R. F. Elmore (1978). It is argued that evaluation will only really be effective when its focus, methods, and management reflect realistic assumptions about how organizations…

Describes analyses based on 35 studies on effectiveness of Grief Therapy. Clients with no-treatment control groups showed little improvement, possibly because of the relatively long delay between loss and treatment. Client selection procedures appear to contribute strongly to variability in effect size (ESs). The majority of studies involving…

A meta-analysis of instructional research with students with learning disabilities in the domains of word recognition and reading comprehension indicates effect sizes for comprehension measures were higher when studies included derivatives of both cognitive and direct instruction, whereas effect sizes were higher for word recognition when studies…

A meta-analysis of 21 studies compared the effectiveness of computer-assisted instruction (CAI) with traditional instruction. Results showed that CAI focusing on higher-order learning in technical education was more effective. (Contains 38 references.) (JOW)

This meta analysis examines the effect of computer-assisted instruction (CAI) upon college student performance, addresses the impact of various study characteristics upon effects, and explores how media richness theory may predict CAI performance gains. Findings indicate that student performance gains are larger for CAI than traditional…

In their article "Scholars Before Researchers: On the Centrality of the Dissertation Literature Review in Research Preparation", David N. Boote and Penny Beile argue that the literature review is the fundamental task of dissertation and research preparation. They claim that doctoral students receive minimal formal training, and little guidance…

This article is a review of the literature related to the reading attitudes and the instructional methods of teaching reading. The article provides a synthesis of previous studies on the reading attitudes of elementary school students in the United States and also addresses a brief review of literature on historic and traditional methods of…

We conducted a reliability generalization meta-analysis to examine the internal consistency of Dyadic Adjustment Scale (DAS; Spanier, 1976) scores across 91 published studies with 128 samples and 25,035 participants. The DAS was found to produce total and Dyadic cohesion, Consensus, and Satisfaction scores of acceptable internal consistency,…

An early version of this article, discussing curricular interventions in mathematics, was written for the What Works Clearinghouse (WWC). The Institute of Education Sciences (IES), which funds WWC, instructed WWC not to publish it. An expanded version, written at WWC's invitation for a special issue of an independent electronic journal and a book…

Many studies over the last 20--25 years have examined the benefits of mentoring for the protege and the organization. A review of these studies being published revealed that there is not only a lack of studies utilizing or reporting comparison group information but also a general lack of experimental research about mentoring. This quantitative…

The authors investigated the effect of chronic exercise on feelings of energy and fatigue using meta-analytic techniques. Chronic exercise increased feelings of energy and lessened feelings of fatigue compared with control conditions by a mean effect delta of 0.37. The effect varied according to the presence or absence of a placebo control or…

Meta-analyses of studies yielding sex-specific risk of potentially traumatic events (PTEs) and posttraumatic stress disorder (PTSD) indicated that female participants were more likely than male participants to meet criteria for PTSD, although they were less likely to experience PTEs. Female participants were more likely than male participants to…
