Children tend to overestimate their performance on a variety of tasks and activities. The present meta-analysis examines the specificity of this phenomenon across age, tasks, and more than five decades of historical time (1968-2021). Self-overestimation was operationalized as the ratio between children's prospective self-estimates of task…

This study employs meta-analysis to synthesize findings from 30 articles investigating gender differences in computational thinking (CT) among K-12 students. Encompassing 51 independent effect sizes, the meta-analysis involves a participant pool of 9181 individuals from various countries, comprising 4254 males and 4927 females. Results indicate…

The study of language maintenance and shift (LMS) has attracted a large body of empirical work in language policy and planning (LPP) contexts, including allochthonous (immigrant) and autochthonous (indigenous) languages. However, some critical ontological questions that relate to the scope and terminology of language maintenance studies remain…

This article presents results from an extensive systematic and meta-analytical review of the effectiveness of school-based bullying prevention programs. Its main aim is to explore the results of this meta-analysis specifically in regard to variations in the effectiveness of school-bullying programs globally and the effectiveness of specific…

The current study provides a systematic examination of child care quality around the globe, using the Environment Rating Scales (ERS). Additional goals of this study are to examine associations between ERS process quality and structural features (group size, caregiver-child ratio) that underpin quality and between ERS and more proximal aspects of…

This meta-analysis examines current North American research on the work of school principals in the special education milieu. More specifically, it considers how elementary and secondary principals envision and act in ways that foster inclusion within a school community. Three core special education-oriented domains arose in the 19 studies…

The field of distance education is composed of a multiplicity of topics leading to a vast array of research literature. However, the research does not provide a chronological picture of the topics it addresses, making it difficult to develop an overview of the evolution and trends in the literature. To address this issue, a co-word analysis was…

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…
