In 2 Monte Carlo studies of fixed- and random-effects meta-analysis for correlations, A. P. Field (2001) ostensibly evaluated Hedges-Olkin-Vevea Fisher-[zeta] and Schmidt-Hunter Pearson-r estimators and tests in 120 conditions. Some authors have cited those results as evidence not to meta-analyze Fisher-[zeta] correlations, especially with…

A meta-analysis was conducted on the effects of multiple-choice and open-ended formats on L1 reading, L2 reading, and L2 listening test performance. Fifty-six data sources located in an extensive search of the literature were the basis for the estimates of the mean effect sizes of test format effects. The results using the mixed effects model of…

Although the student evaluation of teaching has been extensively researched, no general consensus has been reached about the validity of the process. One contentious issue has been the relationship between the evaluations and learning. If good instruction increases the amount of learning that takes place, then learning and the evaluations should…

However intuitively appealing the notion is that therapists learn from clinical experience (presumably both successes and failures), whether clinical judgment actually is enhanced by experience remains a matter on which there continues to be disagreement. The author discusses the meta-analysis of P.M. Spengler et al. that demonstrates a supportive…

The purpose of the present study was to synthesize research that compares children with and without reading disabilities (RD) on measures of short-term memory (STM) and working memory (WM). Across a broad age, reading, and IQ range, 578 effect sizes (ESs) were computed, yielding a mean ES across studies of -0.89 (SD = 1.03). A total of 257 ESs…

Eating disorder not otherwise specified (EDNOS) is the most prevalent eating disorder (ED) diagnosis. In this meta-analysis, the authors aimed to inform Diagnostic and Statistical Manual of Mental Disorders revisions by comparing the psychopathology of EDNOS with that of the officially recognized EDs: anorexia nervosa (AN), bulimia nervosa (BN),…

This mixed methods examination of 710 research articles in mathematics education published in six prominent educational journals during the period 1995-2005 finds that 50% of the studies used qualitative methods only, 21% used quantitative methods only, and 29% mixed qualitative and quantitative methods in various ways. Although the number of…

This report presents results from a new quantitative synthesis of research on the effectiveness and validity of test accommodations for English language learners (ELLs) taking large-scale assessments. In 2006, the Center on Instruction published a review of the literature on test accommodations for ELLs titled "Practical Guidelines for the…

The authors sought to (a) identify interventions that immediately increased the oral reading fluency of students with or at risk for disabilities, (b) estimate to what extent these gains maintained over time, and (c) evaluate whether particular characteristics of students (e.g., gender, disability status) predicted their response to fluency…

Problem-based learning (PBL) is an instructional strategy that is poised for widespread application in the current, growing, on-line digital learning environment. While enjoying a track record as a defensible strategy in face-to-face learning settings, the research evidence is not clear regarding PBL in on-line environments. A review of the…

This review examines 105 empirical studies that investigate students' views of the nature of science (VNOS), effects of curricular interventions on changing students' VNOS, and relations between VNOS and demographics, majors, and learning of science. The reviewed studies can be categorized into three theoretical frameworks: the unidimension, the…

This article summarizes research examining the relationship between the constructs of ethnic identity and personal well-being among people of color in North America. Data from 184 studies analyzed with random effects models yielded an omnibus effect size of r = 0.17, suggesting a modest relationship between the 2 constructs. The relationship was…

Objective: The authors conducted a meta-analysis of empirical studies investigating associations between indices of posttraumatic stress disorder (PTSD) and intimate relationship problems to empirically synthesize this literature. Method: A literature search using PsycINFO, Medline, Published International Literature on Traumatic Stress (PILOTS),…

We previously reported a meta-analysis of explicit memory studies in populations with intellectual disability (ID). The current study discusses the educational implications of this meta-analysis. The main factors at the core of these implications can be divided into two categories: those related to task characteristics (e.g., depth of processing,…

The first year of college is unique and important for many reasons that warrant focused research. Students are often solely responsible for making many academic decisions for the first time as well as living relatively, independently away from home. One apparent consequence of these challenges is that this is the peak time for dropping out of…
