Context: A perennial problem in applied statistics is the inability to justify strong claims about cause-and-effect relationships without full knowledge of the mechanism determining selection into treatment. Few research designs other than the well-implemented random assignment study meet this requirement. Researchers have proposed partial…

Background: Systematic reviews and meta-analyses of interventions can provide critical evidence for educators and policymakers by providing insights into the effectiveness of related interventions. The quality of included studies builds the foundation for a high-quality review, while bias in the included studies increases the risks of unreliable…

Strength training (ST) or resistance training is important in the development and maintenance of musculoskeletal and cardiovascular health in women of all ages; however, uptake of ST amongst women is low. To improve female musculoskeletal health, it is vital that more women are encouraged to participate in ST to maintain musculoskeletal integrity.…

Understanding distinctions between morality and conventions is an important milestone in children's moral development. The current meta-analysis integrated decades of social domain theory research (Smetana, 2006; Turiel, 1983) on moral and conventional judgments from early to middle childhood. We examined 95 effect sizes from 18 studies (2,707…

Studies have reported that physical exercise reduces maladaptive stereotyped motor behaviours (SMB) in children with ASD, but these intervention studies vary in design and outcome. The present systematic review and meta-analysis included 22 studies, involving 274 children with ASD, to quantify the effect of exercise on SMB and its potential…

Bayesian methods seem a natural choice for combining sources of evidence in meta-analyses. However, in practice, their sensitivity to the choice of prior distribution is much less attractive, particularly for parameters describing heterogeneity. A recent non-Bayesian approach to fixed-effects meta-analysis provides novel ways to think about…

In fields (such as population health) where randomised trials are often lacking, systematic reviews (SRs) can harness diversity in study design, settings and populations to assess the evidence for a putative causal relationship. SRs may incorporate causal assessment approaches (CAAs), sometimes called 'causal reviews', but there is currently no…

In recent decades, increased scholarly attention has been paid to the interactions between immigration, media coverage, framing, and the rise of populism. This paper draws on these interactions to systematically review peer-reviewed articles related to media representations of immigrants and refugees in Brazil and the United Kingdom (UK). The…

The relationship between motor skills and executive functions (EFs) is gaining prominence in the field of developmental psychology. However, evidence of the motor skills--EFs link in children with typical development is somewhat inconsistent and there has been no adequate attempt to evaluate it systematically across studies. In view of this, the…

Using the Hartung-Knapp method and 95% prediction intervals (PIs) in random-effects meta-analyses is recommended by experts but rarely applied. Therefore, we aimed to reevaluate statistically significant meta-analyses using the Hartung-Knapp method and 95% PIs. In this methodological study, three databases were searched from January 2010 to July…

The unpredictable pandemic has drastically altered learning approaches, where online learning has been booming. Through VOSviewer, this study visualizes the network of top authors, organizations, sources, and countries that have been devoted to online learning. Through meta-analyses via Stata/MP 14.0, this study identifies nine variables that may…

The aim of this study is to explore the effect size of the drama approach used in the social studies course on academic achievement through the meta-analysis method in the Turkish sample. The academic studies included in this study were searched at the following databases, namely, National Thesis Centre of the Council of Higher Education (YÖK),…

Reflective thinking is a must-have skill to connect the knowledge obtained with previous knowledge and can be seen from learning achievement. This study aims to prove and determine the relationship between reflective thinking and learning achievement and its effect size. This study used a quantitative meta-analysis method. Reflective thinking is…

Evaluative skill, the ability to accurately assess ideas in terms of originality or creativity, is a critical component of creativity. It involves discarding bad ideas and discerning ideas that are worthwhile to pursue. In light of the growing research on the association between individuals' evaluative skill and divergent thinking (DT), a research…

Creativity is essential for the sustainable development of both individuals and organizations. The constant permeation of technology into everyday life is expected to facilitate the cultivation of creativity. To date, no consistent answer has been reached regarding the effect of technology on creativity. This study conducted a three-level…
