Climate in the classroom is one of the determining factors in the development of practices in Inclusive Education. Many factors contribute to the climate in the classroom. However, there are predominance on affective-relational factors, with impact on action, norms and values, social interactions and learning processes. In this paper, the authors…

Purpose: This meta-analysis aims to verify the efficacy of occupational health and safety (OHS) training in terms of knowledge, attitude and beliefs, behavior and health. Design/methodology/approach: The authors included studies published in English (2007-2014) selected from ten databases. Eligibility criteria were studies concerned with the…

The main purpose of this study is to determine the effect of multiple intelligences theory (MIT)-based education on students' academic achievement. In this research, the meta-analytic method was adopted to determine this effect, and studies related to this subject carried out in Turkey were compiled. The effect sizes of the studies included in the…

This methodological brief introduces basic procedures and issues for conducting a high-quality meta-analysis in gifted education. Specifically, we discuss issues such as how to select a topic and formulate research problems, search for and identify qualified studies, code studies and extract data, choose and calculate effect sizes, analyze data,…

How parents interact with their children impacts many crucial facets of children's lives. Over the last 4 decades, researchers have identified four different parenting styles: authoritative, authoritarian, permissive, and disengaged. Hundreds of studies conducted all over the world, have identified correlations between parenting style and many…

Written corrective feedback (WCF) is an instructional strategy used to help second/foreign language (L2) learners improve their writing effectiveness. Teachers can design and provide WCF across a number of dimensions such as focus (e.g. grammar, organization, content), type (e.g. direct correction, reformulation, comment), and tone (e.g. negative,…

Distributed data networks representing large diverse populations are an expanding focus of drug safety research. However, interpreting results is difficult when treatment effect estimates vary across datasets (i.e., heterogeneity). In a previous study, risk estimates were generated for selected drugs and potential adverse outcomes. Analyses were…

Motivated by our meta-analytic dataset involving survival rates after treatment for critical leg ischemia, we develop and apply a new multivariate model for the meta-analysis of study level survival data at multiple times. Our data set involves 50 studies that provide mortality rates at up to seven time points, which we model simultaneously, and…

The main aim of this study was to gather teachers' views to determine the effect size of gender differences on the instructional leadership behavior of school principals. The standardized mean difference (SMD) was calculated to measure the effect size in this study. An initial search yielded 126 studies on the research topic, which consists…

Despite increased attention to methodological rigor in education research, the field has focused heavily on experimental design and not on the merit of replicating important results. The present study analyzed the complete publication history of the current top 100 education journals ranked by 5-year impact factor and found that only 0.13% of…

We conducted a systematic review and meta-analysis to determine the effect of changes to the Diagnostic and Statistical Manual (DSM)-5 on autism spectrum disorder (ASD) and explore policy implications. We identified 418 studies; 14 met inclusion criteria. Studies consistently reported decreases in ASD diagnosis (range 7.3-68.4%) using DSM-5…

This paper examines sources of potential bias in systematic reviews and meta-analyses which can distort their findings, leading to problems with interpretation and application by practitioners and policymakers. It follows from an article that was published in the "Canadian Journal of Communication" in 1990, "Integrating Research…

This piece presents a theoretical exploration of the potential for the creation of policy that would inform the inclusion of arts and particularly theater courses in all community colleges. In April 2017, Fong et al. released a comprehensive meta-analysis that explored the relationship between psychosocial factors of self-perception and motivation…

This meta-analysis summarizes the influence of Turkish teacher's gender and marital status on their perception of organizational commitment. In total, 30 independent research studies conducted across the country are investigated to analyze the relations between gender and organizational commitment, i.e., a sample group of 11,724 participants. In…

This research compiles experimental studies from 1988 to 2010 that examined the influence of the cooperative learning method, as compared with that of traditional methods, on mathematics achievement and on attitudes towards mathematics. The related field was searched using the following key words in Turkish "matematik ve isbirlikli ögrenme,…
