This Research Update synthesizes findings from the profiles of 15 research and evaluation reports added to the Out-of-School Time Program Research and Evaluation Database in December 2006. It highlights strategies for assessing program processes as well as key outcomes and features of programs that promote positive outcomes. The Harvard Family…

In the USA, many environmental educators have paid little attention to Western Christian and Jewish ecotheology, in spite of its being a potentially rich resource for environmental education. In part, this neglect can be attributed to popular misconceptions about the influence of religious beliefs on environmental values. This essay reviews the…

As part of the accountability movement, schools are increasingly called upon to provide interventions that are based on sound scientific research and that provide measurable outcomes for children. Brain Gym[R] is a popular commercial program claiming that adherence to its regimen will result in more efficient learning in an almost miraculous…

A meta-analysis was performed to synthesize existing research comparing the effects of computer-assisted instruction (CAI) versus traditional instruction (TI) on students' achievement in Taiwan. Fifty-two studies were located from four sources, and their quantitative data was transformed into effect size (ES). The overall grand mean of the…

Practical meta-analysis of correlation matrices generally ignores covariances (and hence correlations) between correlation estimates. The authors consider various methods for allowing for covariances, including generalized least squares, maximum marginal likelihood, and Bayesian approaches, illustrated using a 6-dimensional response in a series of…

The relationship between intelligence and socioeconomic success has been the source of numerous controversies. The present paper conducted a meta-analysis of the longitudinal studies that have investigated intelligence as a predictor of success (as measured by education, occupation, and income). In order to better evaluate the predictive power of…

Using meta-analysis, randomized experiments in education that either clearly did or clearly did not experience student attrition were examined for the baseline comparability of groups. Results from 35 studies suggested that after attrition, the observed measures of baseline comparability of groups did not differ more than would be expected given…

The literature on Web-based instruction (WBI) is reviewed, focusing initially on the terminology, history, and commentary (pro and con) related to the topic. The advantages and disadvantages associated with WBI are then discussed and an overview of the empirical work on WBI, paying particular attention to studies on student satisfaction and…

The purpose of this meta-analysis was to synthesize findings from 42 interventions (randomized control trials and quasi-experimental studies) on instructional approaches that enhance the mathematics proficiency of students with learning disabilities. We examined the impact of four categories of instructional components: (a) approaches to…

Purpose: This study assessed the psychometric properties of instruments used to measure constructs similar to stuttering-specific health-related quality of life. In the stuttering literature, most such instruments were originally intended to measure speakers' attitudes about, or reactions to, their stuttering. Method: Seventeen instruments were…

This study explores the predictive validity of GMAT[R] scores for predicting performance in graduate management programs outside the United States. Results suggest that the validity estimates based on the combination of GMAT[R] scores were about a third of a standard deviation higher for non-U.S. programs compared with existing data on U.S.…

Purpose: The purpose of this paper is to analyze a new research topic, national human resource development (NHRD) for neglected but critical components of economics foundation and accumulated international development research and practices. Design/methodology/approach: Through a targeted literature review on NHRD writing, major development…

In light of a recent revelation that Gersten (1985) included erroneous information on one of two programs for English Language Learners (ELLs), the authors re-calculate results of their earlier meta-analysis of program effectiveness studies for ELLs in which Gersten's studies had behaved as outliers (Rolstad, Mahoney & Glass, 2005). The correction…

Today's college students, the Net generation, have woven technology into their everyday repertoire of communication and connection tools. They use the Internet, e-mail, instant messaging, blogs, and social networking Web sites like Facebook and MySpace at higher rates than individuals from any other generation. Student affairs professionals,…

Following the 2005 London bombings, there is widespread public debate about diversity, integration, and multiculturalism in Britain, including the role of education in promoting national identity and citizenship. In response to official concerns about terrorism, a review panel was invited to consider how ethnic, religious and cultural diversity…
