In a meta-analysis, it is important to specify a model that adequately describes the effect-size distribution of the underlying population of studies. The conventional normal fixed-effect and normal random-effects models assume a normal effect-size population distribution, conditionally on parameters and covariates. For estimating the mean overall…

Evidence that rapid naming skill is associated with reading ability has become increasingly prevalent in recent years. However, there is considerable variation in the literature concerning the magnitude of this relationship. The objective of the present study was to provide a comprehensive analysis of the evidence on the relationship between rapid…

Research synthesis and meta-analysis provide a pathway to bring together findings in a given domain with greater systematicity, objectivity, and transparency than traditional reviews. The same techniques and corresponding benefits can be and have been applied to examine methodological practices in second language (L2) research (e.g., Plonsky,…

The purpose of this study is to illustrate the multilevel meta-analysis of results from single-subject experimental designs of different types, including AB phase designs, multiple-baseline designs, ABAB reversal designs, and alternating treatment designs. Current methodological work on the meta-analysis of single-subject experimental designs…

Outdoor adventure education (OAE) has a long history of being credited with the personal and social development (PSD) of its participants. PSD is notoriously difficult to measure quantitatively, yet stakeholders demand statistical evidence that given approaches to eliciting PSD are effective in their methods. Rightly or wrongly, many stakeholders…

The purpose of this systematic review and meta-analysis was to synthesize the available research on the "Skills for Social and Academic Success" ("SASS") program, a school-based cognitive/behavioural intervention for adolescents with social anxiety disorder. A search of online databases, combined with reference list examination…

Child gender has been proved to affect toddlers'/children's language development in several studies, but its effect was not found to be stable across different ages or various aspects of language ability. The effect of gender on toddler's, children's and adolescents' language ability was examined in the present meta-analysis of ten Slovenian…

The testing effect is a robust empirical finding in the research on learning and instruction, demonstrating that taking tests during the learning phase facilitates later retrieval from long-term memory. Early evidence came mainly from laboratory studies, though in recent years applied educational researchers have become increasingly interested in…

The "summer learning effect" (SLE) is described as a stall or drop in achievement over summer, especially in schools serving poor or "minority" communities. There has been little research in Europe on the effect, and research internationally has primarily focused on the effect in reading, with minimal focus on writing. This…

The primary purpose of this study was to determine what trends exist in the identification and description of participants with disabilities used in school-based physical education research. A total of 60 research articles published in the "Journal of Teaching in Physical Education" from 2010-2014 which included school-aged individuals…

In response to policy initiatives calling for the implementation of evidence-based classroom practice, instructional coaches are frequently utilized as providers of professional development (PD). Despite the demand for instructional coaches, there is little empirical evidence that coaching improves teacher practice. We address this limitation by…

Most research on online learning in higher education has been focused on general education at four-year institutions. There is a need for more research that focuses on online and hybrid education at community colleges in technical education fields. This issue includes articles from eight National Science Foundation funded projects doing innovative…

The aim of this study is to investigate recent empirical research studies about 3D virtual learning environments. A total of 167 empirical studies that involve the use of 3D virtual worlds in education were examined by meta-review. Our findings show that the "Second Life" platform has been frequently used in studies. Among the reviewed…

Feedback is frequently highlighted as a key contributor to students' learning. This literature study argues that the focus of some of the feedback literature appears too narrow to understand what is going on in a classroom. Parts of the feedback literature show the relationship between feedback and learning approximate to a process-product model…

This paper analyses the bibliometric characteristics of 616 journal articles on key competences indexed in ERIC in a 23-year-period following documentary analysis. This observation method allowed us to highlight key elements like the population, educational level, topics, etc. to focus whether this literature contributes towards implementing…
