The purpose of this systematic review and meta-analysis was to synthesize the available research on the "Skills for Social and Academic Success" ("SASS") program, a school-based cognitive/behavioural intervention for adolescents with social anxiety disorder. A search of online databases, combined with reference list examination…

Evaluations of a large federally funded sexual risk avoidance education (SRAE) efforts in the USA have not been widely reported in the wake of funding cuts. The purpose of this study is to report results from a broad set of programmes to demonstrate the breadth of field effectiveness of these programmes. Twenty-seven separate community-based SRAE…

Extensive research has examined the effectiveness of admissions tests for use in higher education. What has gone unexamined is the extent to which tests are similarly effective for predicting performance at both the master's and doctoral levels. This study empirically synthesizes previous studies to investigate whether or not the Graduate Record…

This paper uses data from the Head Start Impact Study (HSIS), a nationally representative multisite randomized trial, to quantify variation in effects of Head Start during 2002-2003 on children's cognitive and socio-emotional outcomes relative to the effects of other local alternatives, including parent care. We find that (1) treatment and control…

This article synthesizes the literature comparing at-risk children designated as responders and low responders to interventions in reading. The central question addressed in this review is whether individual differences in reading-related skills at pretest predict responders at posttest across a variety of interventions and sets of criteria for…

Charter schools are largely viewed as a major innovation in the public school landscape, as they receive more independence from state laws and regulations than do traditional public schools, and are therefore more able to experiment with alternative curricula, pedagogical methods, and different ways of hiring and training teachers. Unlike…

The Focused Practice Instructional Approach (FPIA) was based on the Environmental Mode of instruction established by George Hillocks' 1986 meta-analysis for writing instruction. The purpose of this study was to clearly define the FPIA approach using the original studies and test if it was significantly effective in fourth grade classrooms using…

A meta-analysis was conducted to examine the degree to which teachers' test scores and their performance in preparation programs as measured by their collegiate grade point average (GPA) predicted their teaching competence. Results from 123 studies that yielded 715 effect sizes were analyzed, and the mediating effects of test and GPA type,…

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.…

Three meta-analytic studies have shown that bilingual education is an effective method for teaching students who are English language learners. However, there is limited evidence of the effectiveness of bilingual education in preschool. This study used multiple years of data from the Manchester (New Hampshire) Even Start program and relevant…

A quantitative method, meta-analysis, is used to integrate research findings from a representative group of 38 coaching studies. Because different studies reported results on different scales, effect size was used to transform all results to a common metric. This meta-analysis showed that there are two distinct literatures on the effectiveness of…

This review examines empirically based studies of school-based mental health interventions. The review identified 64 out of more than 2,000 articles published between 1990 and 2006 that met methodologically rigorous criteria for inclusion. Of these 64 articles, only 24 examined both mental health "and" educational outcomes. The majority of…

Results of a previous meta-analysis of gender differences in reading achievement at the secondary school level (Lietz, in press) showed significant differences between major assessment programs. Thus, the gender gap in favour of girls was more pronounced for the assessment programs conducted by the National Assessment of Educational Programs in…
