According to the socio-ecological model, the social environment contributes to the acquisition and maintenance of negative attitudes towards ethnic minority groups. However, the strength of the association between negative attitudes at different levels (i.e. individual, peers) and ethnic bullying and discrimination has not yet been assessed. A…

Purpose: Accelerating the adoption of intensification methods is critical for improving African agricultural productivity growth. This study synthesizes the effect of determinants underlying the speed of adoption of agricultural intensification methods in Africa. Design/Methodology/Approach: A systematic literature search was conducted using…

Negative cognitions play a key role in the development and maintenance of depression. To reduce depressive symptoms, most interventions either encourage adolescents to change negative cognitions, theorizing that the presence of negative cognitions underlies depression, or to acknowledge negative cognitions, theorizing that one's reaction to…

Mathematical problem posing, generally defined as the process of interpreting given situations and formulating meaningful mathematical problems, is academically important, and thus several interventions have been used to enhance this competence among students and teachers. Yet little is known about the interventions' various components and their…

Anatomy is the cornerstone of medical education. Virtual reality (VR) and augmented reality (AR) technologies are becoming increasingly popular in the development of anatomy education. Various studies have evaluated VR and AR in anatomy education. This meta-analysis aims to evaluate the effectiveness of VR and AR in anatomical education. The…

Studies on learning strategies across cultures in higher education inform the internationalisation of teaching and learning. Previous comparisons relied on geographical generalisations (e.g., "Asian", "Western", "Latin-American") or only variable-centred methods, which can overgeneralise the contexts they represent.…

Scale errors are intriguing phenomena in which a child tries to perform an object-specific action on a tiny object. Several viewpoints explaining the developmental mechanisms underlying scale errors exist; however, there is no unified account of how different factors interact and affect scale errors, and the statistical approaches used in the…

We have entered an era in which scientific evidence increasingly informs research practice and policy. As there is an exponential increase in the use of single-case experimental designs (SCEDs) to evaluate intervention effectiveness, there is accumulating evidence available for quantitative synthesis. Consequently, there is a growing interest in…

Accurate monitoring of performance in problem-solving tasks is an important prerequisite for students' future academic success. A wide variety of interventions aiming to enhance students' monitoring accuracy have been developed, but their effectiveness is not apparent from the individual studies in which they have been examined. This meta-analysis…

The Adult Prosocialness Behavior Scale (APBS) is most often used to measure adult prosociality. We conducted a reliability generalization meta-analysis to compute the average APBS reliability and examine the heterogeneity among reliability estimations and the influence of moderator variables. An exhaustive search identified 74 articles that…

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…
