Self-injurious behaviour is purportedly common in autism, but prevalence rates have not yet been synthesised meta-analytically. In the present study, data from 14,379 participants in thirty-seven papers were analysed to generate a pooled prevalence estimate of self-injury in autism of 42% (confidence intervals 0.38-0.47). Hand-hitting topography…

The aim of this study was to determine the effect of creative drama method on the Social Studies course achievement of students. Within the scope of the research, in Google Academic, EBSCOhost, ERIC, ULAKBIM TR Index, thesis databases of the Higher Education Council in Turkey (YÖK), a search was conducted via the key words "drama, creative…

Network meta-analysis has been gaining prominence as an evidence synthesis method that enables the comprehensive synthesis and simultaneous comparison of multiple treatments. In many network meta-analyses, some of the constituent studies may have markedly different characteristics from the others, and may be influential enough to change the…

Access to knowledge has never been easier in the internet age, and so it is important that students develop skills to discriminate undependable information from reliably investigated research. We have created an exercise that teaches good research practice by exploring the history, ethics, and design of clinical trials. Students apply their…

Technology-enabled active learning environments (TE-ALEs) have attracted considerable research interest, particularly in higher education. However, research shows inconsistent results describing the influence of TE-ALEs toward students' cognitive learning outcomes. This study was designed to identify high-quality empirical research examining…

Many randomized trials evaluate an intervention effect on time-to-event outcomes. Individual participant data (IPD) from such trials can be obtained and combined in a so-called IPD meta-analysis (IPD-MA), to summarize the overall intervention effect. We performed a narrative literature review to provide an overview of methods for conducting an…

Research synthesis on simple yet general hypotheses and ideas is challenging in scientific disciplines studying highly context-dependent systems such as medical, social, and biological sciences. This study shows that machine learning, equation-free statistical modeling of artificial intelligence, is a promising synthesis tool for discovering novel…

This study analyzes empirical evidence that compared face-to-face and online education. A meta-analysis points to various gaps in research, including how policy and curriculum development should be guided in this fast-moving education medium. Significant gaps remain, especially in the area of adaptability of both faculty and students to various…

This study aimed to determine for continuous outcomes dependent on baseline risk, whether funnel plot asymmetry may be due to statistical artefact rather than publication bias and evaluate a novel test to resolve this. Firstly, we conducted assessment for publication bias in nine meta-analyses of postoperative analgesics (344 trials with 25 348…

Despite the importance of identifying individuals with reading disabilities, existing operational definitions of reading disability do not result in reliable identification. A large part of the problem arises from measurement error when a cut-point is imposed on a continuous distribution, especially for low base-rate conditions. One way to reduce…

This systematic review and meta-analysis examined recent articles that have used the 1995 Draw-A-Scientist Checklist (DAST-C). This study was focused on the current state of students' stereotypes of scientists and the appropriateness of the DAST-C as a tool to assess these perceptions. Articles included in the review were published between 2003…

Background: Although children with intellectual disabilities (ID) are at greater risk of falls from poorer balance ability than typically developing children, reliable information about which types of physical intervention are most effective is scarce. Objective: A meta-analysis was used to examine the most effective programs on balance ability in…

Purpose: The purpose of this study was to investigate whether there are elevated symptoms of anxiety or depression in children and adolescents (aged 2-18 years) who stutter, and to identify potential moderators of increased symptom severity. Method: We conducted a preregistered systematic review of databases and gray literature; 13 articles met…

Ongoing debate exists concerning pedagogical strategies including song to improve vocabulary learning in second or foreign language learners. A search of primary empirical studies published from 1990 to 2020 produced 27 articles with 28 studies and 1864 total participants. Effect sizes were analysed for the influence of English instructional…

E-learning was abruptly adopted as a strategic response to the sudden closure of institutions of learning induced by the COVID-19 pandemic. In contrast to the conventional voluntary adoption of e-learning, this study aims to explore a new trail by drawing challenges of e-learning eclectically from recent literature to develop an alternative…
