Introduction: This paper draws on the results of studies undertaken between 2004 and 2007 as part of Project REVISTAS, supported by the European Commission's ALFA Programme. Method: A variety of methods was employed over the life of the project, including analysis of directories, a survey of universities in the region believed to be offering…

This chapter is about culture and mathematics teaching and learning. The authors' goal is to offer a thoughtful treatment of the role of culture in the teaching and learning of mathematics and to synthesize literature that is relevant to this concern from multiple subdisciplines in education, including math education, educational anthropology,…

Research on effectiveness of school bullying interventions has lagged behind descriptive studies on this topic. The literature on bullying intervention research has only recently expanded to a point that allows for synthesis of findings across studies. The authors conducted a meta-analytic study of school bullying intervention research across the…

Research suggests that exposure to mass media depicting the thin-ideal body may be linked to body image disturbance in women. This meta-analysis examined experimental and correlational studies testing the links between media exposure to women's body dissatisfaction, internalization of the thin ideal, and eating behaviors and beliefs with a sample…

This research synthesis verifies the effectiveness of the Picture Exchange Communication System (PECS) for improving the functional communication skills of individuals with autism spectrum disorders (ASD). The research synthesis was focused on the degree to which variations in PECS training are associated with variations in functional…

What constitutes quality in early childhood settings, and how can it best be measured with today's widely used tools and promising new approaches? Find authoritative answers in this book, a must-have for high-level administrators and policymakers as more and more states adopt early childhood Quality Rating and Improvement Systems. The most…

To respond to Congress' interest in student outcomes at different types of schools, this report addresses the following questions: (1) What does research show about graduation rates, employment outcomes, student loan debts, and default rates for students at for-profit schools compared to those at nonprofit and public schools, taking differences in…

The study used meta-analysis techniques to examine the effectiveness of intervention strategies for children with cerebral palsy. An examination of existing literature on meta-analysis revealed that techniques are available to accommodate a wide variety of research designs and data. Next, the percentage of studies purporting to address an…

Conducted meta-analysis of 108 well-designed outcome studies using 4- through 18-year-old subjects to examine effectiveness of psychotherapy with children and adolescents. Overall, findings revealed significant, durable effects of treatment that differed somewhat with client age and treatment method but which were reliably greater than zero for…

The Meta-Analysis Effect Size Calculator provides the user with many different ways to calculate an effect size depending on the information available in the original research report. In addition, the program computes an unbiased estimate of effect size. (Author)

Evaluated the effectiveness of paradoxical interventions in psychotherapy, in a meta-analysis of 12 data sets. Found that paradoxical interventions were as effective as, but not more effective than, the typical treatment made except for one month after treatment termination and with more severe cases, when it showed relatively greater…

The paper explores the conceptual bases of the controversy over meta analysis and computes it with traditional research on four dimensions: (1) scientific rigor, (2) detecting small effects, (3) problems of oversimplification, and (4) potential policy impact. It is argued that choice of procedures should be determined by the specific purpose of a…

Examined generalizability of treatment studies by comparing solicited and nonsolicited patient groups treated or studied in clinical settings. Findings suggest it may be possible to generate comparable samples in terms of pretreatment symptomatology, however, data are too limited to permit conclusions regarding generalizability of treatment…

As meta-analytic studies have become essential in educational research, resampling methods have matured and are supported by an in-depth theoretical and applied literature base. The objective of this paper is to assist researchers in applying resampling methods to the results of meta-analysis. The rationale for resampling methods is reviewed, and…

The practical significance, usefulness, and generalizability of research have for years hinged on a finding of statistical significance. Voices of reform have called for the use of effect sizes, confidence intervals, and meta-analytic synthesis of research as a way to judge the practical significance and generalizability of a discovery. This paper…
