As Information Technology expands, all industries and fields in Saudi Arabia are experiencing reduced costs and improvements in the efficiency and effectiveness of operations in various systems. This has positioned the higher education sector in Saudi Arabia as the land of opportunity in terms of educational technology and its ability to support…

Asthma is the leading chronic health condition among children in the United States and a major cause of childhood disability. It also disproportionately affects low-income and racial and ethnic minorities. Although a wide range of interventions have been implemented to improve asthma-related outcomes among socioeconomically disadvantaged and…

Background: For a majority of the world's children, despite substantial increases in primary school enrollment, academic learning is neither occurring at expected rates nor supplying the basic foundational skills necessary to succeed in the 21st century. The significant lag in academic achievement tells us that simply making formal education…

This study examined the impact of publication bias on a meta-analysis of empirical studies on validity of University Matriculation Examinations in Nigeria with a view to determine the level of difference between published and unpublished articles. Specifically, the design was an ex-post facto, a causal comparative design. The sample size consisted…

In the present study the results of two meta-analyses on the effectiveness of "individually" delivered indicated school-based interventions for externalizing behavior problems at elementary schools are presented. A distinction was made between studies that evaluated effects of interventions with only an individual component (k = 11 studies, n =…

Many meta-analyses of comparative outcome studies found a substantial association of researcher allegiance (RA) and relative treatment effects. Therefore, RA is regarded as a biasing factor in comparative outcome research (RA bias hypothesis). However, the RA bias hypothesis has been criticized as causality might be reversed. That is, RA might be…

The primary purpose of this study was to examine, using meta-analytical techniques, the differential effects of differing intensities of acute exercise on speed and accuracy of cognition. Overall, exercise demonstrated a small, significant mean effect size (g = 0.14, p less than 0.01) on cognition. Examination of the comparison between speed and…

This study examined interventions for addition and subtraction that were implemented through single-case design (SCD) research studies. We attempted to extend prior SCD meta-analyses by examining differences in effect sizes across several moderating variables and by including a novel index of effect, improvement rate difference (IRD). We also…

This study assessed the effectiveness of culturally sensitive interventions (CSIs) ("N" = 10) designed to address substance use among minority youths. Study methods consisted of systematic search procedures, quality of study ratings, and meta-analytic techniques to gauge effects and evaluate publication bias. The results, across all measures and…

Reviews of the effects of noise on performance carried out in the 1980s suggested that results depended on the type of noise, nature of the task, and characteristics of the person performing in noise. This general view has been confirmed in the recent meta-analysis and synthesis by Szalma and Hancock (2011). There are, however, some notable…

Meta-analysis was used to comprehensively summarize the relationship between dispositional variables and both directions of work-family conflict. The largest effects detected were those associated with negative affect, neuroticism, and self-efficacy; all were in expected directions. In general, negative trait-based variables (e.g., negative affect…

This dissertation builds on and extends research on the relationship between equity-minded mathematics teaching, specifically teaching mathematics for social justice, complex instruction, and project-based learning, and students' learning and identity development. Although different in their structures and strategies, equity-minded mathematics…

The purpose of this descriptive paper was to explore and synthesize literature related to understanding modular learning and how it can be implemented effectively so faculty members embrace its use. An in-depth review of literature addressed topics including, Educational Theories supporting modular learning, the development of modular learning,…

This study examines how design characteristics in digital simulation-based learning environments moderate self-efficacy and transfer of learning. Drawing on social cognitive theory and the cognitive theory of multimedia learning, the meta-analysis psychometrically cumulated k?=?15 studies of 25 years of research with a total sample size of…

This article presents a meta-analysis of one area of sociological literature in music education: Where are the women and "others"? Where do we raise concerns about social values? Institutional Ethnography provides the basis for the meta-analysis, presented in two historical periods, pre-1960 and 2007-2012. A short story of an actual…
