Using meta-analytic techniques, results were synthesized from 58 empirical sources on the association between being married and subjective well-being (SWB). Results indicated that being married was positively and significnatly associated with SWB. However, the magnitude of this association was weaker than expected. (Author/BL)

The homogeneity test provided by L. Hedges (1982) in meta-analysis has been widely used, mainly to test if the effect sizes share the same variance. Ignoring the intercorrelations among effect sizes affects the Type I error rate. The main purpose of this research was to study the impact of pooling effect sizes on the homogeneity test in effect…

Many researchers fail to understand that reliability is a function of scores, not tests. This paper provides an explanation of the distinction as well as a description of the reliability generalization meta-analysis technique. Reliability generalization meta-analysis can provide a way to aggregate test score reliability coefficients from prior…

Examines the use of conceptual frameworks in collecting qualitative data from multiple sites. Presents strategies for devising frameworks that are flexible and general without sacrificing specificity. (JOW)

Conducted a reliability generalization study for the State-Trait Anxiety Inventory (C. Spielberger, 1983) by reviewing and classifying 816 research articles. Average reliability coefficients were acceptable for both internal consistency and test-retest reliability, but variation was present among the estimates. Other differences are discussed.…

Comments on the article by J. S. Hyde (see record EJ733581), which reviewed the results of 46 meta-analyses of studies investigating gender differences and produced results that supported the gender similarities hypothesis that men and women are similar along most psychological traits. The current authors agree with the gender similarities…

Many have elaborated on the potential of virtual reality (VR) in learning. This article attempts at organizing the literature in this issue in order to better identify indicators that can account for future valid trends, and seeks to bring to attention how authors who wrote about the future of VR in education confused futures' terms and produced…

The 2001 renewal of the United States' Title I program, which provides federal funds to schools with large populations of low-income students, instituted the Supplemental Educational Services (SES) program in which schools in their third year of failing to make Adequate Yearly Progress (AYP) are required to offer after-school tutoring in core…

Meta-analysis was applied to study the empirical research from 1990-2007 regarding the effectiveness of the dating violence prevention programs in middle and high schools on students' knowledge and attitudes. The results show that overall the program participants improved their knowledge and attitudes towards dating violence. Implications for…

Including English language learners (ELLs) in large-scale assessments raises questions about the validity of inferences based on their scores. Test accommodations for ELLs are intended to reduce the impact of limited English proficiency on the assessment of the target construct, most often mathematic or science proficiency. This meta-analysis…

This study examined the percentage of task-sampling variability in performance assessment via a meta-analysis. In total, 50 studies containing 130 independent data sets were analyzed. Overall results indicate that the percentage of variance for (a) differential difficulty of task was roughly 12% and (b) examinee's differential performance of the…

This article describes how one university-based center, UCLA's Center X, has worked to prepare and sustain urban educators over the past 16 years. Synthesizing findings from more than 20 articles, papers, books, and dissertations that report on Center X's work, we argue that three key activities are necessary to spur change and ensure a…

The relationship between functional or life skills curricula (the intervention) and transition-related outcomes for secondary-aged youth with disabilities is explored in this systematic review. A total of 50 studies intervening with 482 youth with (largely) disability labels of moderate to severe mental retardation were reviewed. The findings of…

While e-learning, Web-enhanced instruction, and other forms of instructional technology have been touted as an effective way of addressing student withdrawal and academic performance, there are those (Carr, 2000) that report both program and end-of-semester course completion rates in distance education courses as merely acceptable compared to more…

New emphasis is being placed on the importance of parent involvement in children's education. In a synthesis of research on the effects of parent involvement in homework, a meta-analysis of 14 studies that manipulated parent training for homework involvement reveals that training parents to be involved in their child's homework results in (a)…
