Background: Intellectual disability (ID) affects 1%-3% of the paediatric population. Currently, there is no consensus as to the most effective strategies for improving the learning skills of children and adolescents with ID. This review aims to systematically gather information regarding interventions to promote and improve learning skills in…

The number of clinical prediction models sharing the same prediction task has increased in the medical literature. However, evidence synthesis methodologies that use the results of these prediction models have not been sufficiently studied, particularly in the context of meta-analysis settings where only summary statistics are available. In…

It may be possible to teach students in undergraduate research methods courses about replication, while simultaneously providing the discipline a means to solve what some have called a replication "crisis." Over the span of three consecutive fall semesters, students replicated Cialdini and Schroeder's "even a penny will help"…

Can well-documented gender differences in evaluations of prosocial versus antisocial actions found in childhood and adulthood be traced to sex differences in basic sociomoral preferences in infancy? We provide an answer to this question by meta-analyzing sex differences in preference for prosocial over antisocial agents in a set of 53 samples of…

Mental rotation, the cognitive process of moving an object in mind to predict how it looks in a new orientation, is coupled to intelligence, learning, and educational achievement. On average, adolescent and adult males solve mental rotation tasks slightly better (i.e., faster and/or more accurate) than females. When such behavioral differences…

This research aims to prove and find out the influence of local wisdom-based learning media on the character of students in Indonesia. This research uses a quantitative method with a meta-analysis approach. The research data were analyzed using the 0.8.5 version of JASP software. The eligibility criteria used include: (a) The publications must be…

As the world rapidly changes and develops, students are finding it increasingly difficult to achieve their goals. In this era where traditional education methods are being scrutinized for their impact on academic success, educators are exploring various teaching techniques to improve academic outcomes. The Six Thinking Hats Technique (STHT) is one…

This article systematically reviews the pedagogical approaches adopted in high school chemistry education with the aim of highlighting the most effective evidence-based instructional practices reported in the literature. For this, a meta-analysis of 35 pedagogical approaches is analyzed, and their effect sizes (Cohen's d) are compared in terms of…

In 2009, John Hattie's book Visible Learning: A Synthesis of over 800 Meta-Analyses Relating to Achievement brought big data to education. In the decade and a half since Visible Learning was originally published it has been aggressively marketed and has now grown into a large suite of branded books, tools, and products. Visible Learning continues…

Theories of cultural evolution posit that cues of competence-based prestige, rather than formidability-based dominance, should guide culturally transmitted learning, but recent work suggested that French and Kaqchikel Guatamalan preschoolers place their epistemic trust in dominant others. In contrast, this study shows that 249 three- to…

In evidence synthesis, dealing with zero-events studies is an important and complicated task that has generated broad discussion. Numerous methods provide valid solutions to synthesizing data from studies with zero-events, either based on a frequentist or a Bayesian framework. Among frequentist frameworks, the one-stage methods have their unique…

Meta-analysis of proportions is conceptually simple: Faced with a binary outcome in multiple studies, we seek inference on some overall proportion of successes/failures. Under common effect models, exact inference has long been available, but is not when we more realistically allow for heterogeneity of the proportions. Instead a wide range of…

This article reports a meta-analysis of studies on the effects of teachers' verbal lexical explanation (TVLE), as one type of lexical focus on form, on second language vocabulary learning. The dataset for this meta-analysis included 14 studies, representing a total of 36 independent samples (N = 3,304). The results of this study reveal that TVLE…

Background: This meta-analysis aims to: (i) describe the pooled prevalence of diabetes in people with intellectual disabilities, (ii) investigate the association with demographic, clinical and treatment-related factors and (iii) compare the prevalence versus age- and gender-matched general population controls. Methods: PubMed, Embase and CINAHL…

This article presents a systematic meta-review of the scientific literature discussing the concepts of information literacy, media literacy, and digital literacy. While carrying out a cross analysis of the way in which literature reviews specifically address these three concepts, this article identifies, and articulates a critical analysis of, the…
