A review of studies published between 1980 and 2005 shows a significant positive effect of specialized training on the competency of caregivers in childcare (d=0.45, S.E.=0.10). Experimental results from the meta-analysis were significantly smaller for settings with no fixed curriculum content, delivery of the training at multiple sites and…

Person-centered education is a counseling-originated, educational psychology model, overripe for meta-analysis, that posits that positive teacher-student relationships are associated with optimal, holistic learning. It includes classical, humanistic education and today's constructivist learner-centered model. The author reviewed about 1,000…

Study Purpose: This article examines the influence of "Educational Administration Quarterly (EAQ)" on the scholarly literature in education during the 25-year period 1979 to 2003. This article continues part of the first critique of EAQ conducted by Roald Campbell in 1979. Study Methods: Two citation measures are used in this study to assess EAQ…

Numerous studies show that children's language ability is related to false-belief understanding. However, there is considerable variation in the size of the correlation reported. Using data from 104 studies (N=8,891), this meta-analysis determines the strength of the relation in children under age 7 and examines moderators that may account for the…

The purpose of this synthesis is to summarize the effectiveness of peer-mediated interventions on the mathematics performance of both students with disabilities and those at risk for mathematics disabilities. Meta-analytic techniques were used to calculate mean effect sizes for 17 studies that met inclusion criteria. Results indicate that…

CIRCLE has recently published three detailed fact sheets that update, refine, and in some respects complicate, our knowledge of the links between college education and civic engagement (see "College Attendance and Civic Engagement Among 18 to 25 Year Olds," "Civic Engagement among Recent College Graduates," and "Civic Engagement among 2-year and…

L. L. Bonatti, M. Pena, M. Nespor, and J. Mehler (see record 2006-06642-010) argued that P. Perruchet, M. D. Tyler, N. Galland, and R. Peereman (see record 2004-21166-008) confused the notions of segmentation and generalization by ignoring the evidence for generalization in M. Pena, L. L. Bonatti, M. Nespor, and J. Mehler (see record…

Effect sizes are critical to result interpretation and synthesis across studies. Although statistical significance testing has historically dominated the determination of result importance, modern views emphasize the role of effect sizes and confidence intervals. This article accessibly discusses how to calculate and interpret the effect sizes…

The author comments on the article "The Primacy of Cognition in Schizophrenia," by R. W. Heinrichs and states that to the pursuit of schizophrenic/normal differences, there is no end. Heinrichs used meta-analyses to argue persuasively for the primacy of cognition for this role. His conclusion not only elicited agreement from both researchers and…

This is a compilation of two separate reports on international literacy research from France and Argentina. In the reports from France, research correspondent Jacques Fijalkow detailed three research projects that included the following: (1) A description of adult literacy skills; (2) An investigation of how study-abroad students were integrated…

In this article we briefly examine the meta-analysis of systematic phonics instruction published in "Teaching Children to Read," the influential 2000 report by the National Reading Panel. A brief review of this study, and the ensuing reanalysis by Camilli, Vargas, and Yurecko, is given. Following this, we report new analyses that…

While many studies attest that some teachers contribute more to their students' academic growth than other teachers, research has not been very successful at identifying the specific teacher qualifications, characteristics, and classroom practices that are most likely to improve student learning. Unfortunately, this is just the information that…

The study investigated the power of theoretically derived cognitive variables to predict posttraumatic stress disorder (PTSD), travel phobia, and depression following injury in a motor vehicle accident (MVA). MVA survivors (N = 147) were assessed at the emergency department on the day of their accident and 2 weeks, 1 month, 3 months, and 6 months…

Purpose: The concept of managers assuming developmental roles such as coaches and learning facilitators has received considerable attention in recent years. Yet, despite the growing body of expert opinion that suggests that coaching is an essential core activity of everyday management and leadership, the literature base remains largely…

Objective: To conduct a meta-analysis on randomized, controlled treatment trials of pediatric obsessive-compulsive disorder (OCD). Method: Studies were included if they employed randomized, controlled methodology and treated young people (19 years or under) with OCD. A comprehensive literature search identified 13 RCTs containing 10…
