Objectives: To evaluate the associations of physical education (PE) with school violence and bullying. Design: Systematic review. Method: Using a systematic search in Medline, PsycINFO, SPORTDiscus, Web of Science, and Scopus, relevant studies with a quantitative and qualitative design were identified that met previously established eligibility…

This study utilized the quantitative meta-analysis technique to integrate chemistry education research findings conducted in the Philippines covering the period 2005-2016. It aimed to describe and examine the effects of teaching methodologies on academic performance in the secondary chemistry teaching-learning process. A search procedure and broad…

The focus of the current study is on handling the dependence among multiple regression coefficients representing the treatment effects when meta-analyzing data from single-case experimental studies. We compare the results when applying three different multilevel meta-analytic models (i.e., a univariate multilevel model avoiding the dependence, a…

This book offers practical guidance for understanding and implementing APA Style Journal Article Reporting Standards (JARS) and Meta-Analysis Reporting Standards (MARS) for quantitative research. These standards provide the essential information researchers need to report, including detailed accounts of the methods they followed, data results and…

Many thesis, dissertations, and articles have been written on whether the concept of multiple intelligence has achieved the expected success in educational environments that has been established in accordance with the multiple intelligence principle and whether such developments have had a positive influence on the attitudes of students towards…

The vast majority of meta-analyses uses summary/aggregate data retrieved from published studies in contrast to meta-analysis of individual participant data (IPD). When the outcome is continuous and IPD are available, linear mixed modelling methods can be employed in a one-stage approach. This allows for flexible modelling of within-study…

Background: Model-based meta-analysis (MBMA) is increasingly used to inform drug-development decisions by synthesising results from multiple studies to estimate treatment, dose-response, and time-course characteristics. Network meta-analysis (NMA) is used in Health Technology Appraisals for simultaneously comparing effects of multiple treatments,…

Studies combined in a meta-analysis often have differences in their design and conduct that can lead to heterogeneous results. A random-effects model accounts for these differences in the underlying study effects, which includes a heterogeneity variance parameter. The DerSimonian-Laird method is often used to estimate the heterogeneity variance,…

Social sciences librarians have an interest in supporting systematic reviews, but the available guidance is focused on health sciences settings. This study contributes guidance specifically for social sciences librarians using the Campbell Collaboration's standards to evaluate the search methods reported in systematic reviews on K-12 mathematics…

Background: Adults with intellectual disabilities are reported to be highly inactive, with research required to understand contributory factors. This systematic review aimed to investigate gender differences in physical activity (PA) and sedentary behaviour (SB) in adults with intellectual disabilities. Methods: This systematic review was reported…

The purpose of this study is, by using meta-analysis method, to examine whether there is a significant difference in the effect size of the Technological Pedagogical Content Knowledge (TPACK) according to gender. For this purpose, it was examined whether both Technological Pedagogical Content Knowledge and the knowledge types related to TPACK…

Dissertations present significant challenges to all doctoral students but these challenges are often greater for online students. Research shows that as many as 50% of all doctoral students do not complete their degrees, and this number is likely even higher for online students. One reason for this may be that online doctoral students do not have…

Conceptual frameworks are conjectural/hypothetical research tools that are particularly important and widely used in the disciplined inquiry, including educational (technology) research. However, there is a lack of guidance on how to construct them. Hence, the objective of the current research was to provide a methodological perspective through a…

When considering data from many trials, it is likely that some of them present a markedly different intervention effect or exert an undue influence on the summary results. We develop a forward search algorithm for identifying outlying and influential studies in meta-analysis models. The forward search algorithm starts by fitting the hypothesized…

We describe a meta-analytic scatterplot that indicates precision of points for two variables paired within studies; this is equivalent in form to a 'cross-hairs' plot used to portray specificity and sensitivity in diagnostic testing. At the user's discretion, the plot also displays boxplots for each of the X and Y variable distributions, means for…
