This research study conducted a meta-analysis to integrate the studies that investigated the effectiveness of project-based learning on academic achievement based on a worldwide higher-education population. The researcher explored the variables that previous meta-analysis studies used to evaluate academic achievements, such as student grade point…

There is increasing interest in meta-analysis in different fields due to the need to combine the results of primary research. One of the crucial concepts in combining results is weighting. This study examines how Hunter and Schmidt's method, weighting by sample size; Hedges and Vevea's method, weighting by inverse variance; and Osburn and…

This study aims to determine the effectiveness of ethnomathematics-based learning on students' mathematical literacy through a meta-analysis study. Primary studies were collected from Google Scholar and ERIC databases based on the inclusion criteria. The results of the literature review obtained 16 studies, either from theses, proceedings, or…

A considerable body of literature exists pertaining to realistic mathematics education (RME) and its correlation with mathematical literacy, with numerous studies demonstrating incongruent results. The principal objective of this meta-analysis is to systematically investigate the overarching influence of RME on mathematical literacy within the…

Learning analytics has received increasing attention in the field of education. However, few studies have investigated the overall impact of learning analytics interventions on learning achievements. This study aims to close this research gap and examine the sizes of the overall effects of learning analytics interventions on learning achievements…

The primary goal of this meta-analysis was to estimate the overall size of the relation between rapid automatized naming (RAN) and spelling in alphabetic languages and to examine what factors may moderate their relation. In addition, we examined if the size of the RAN-spelling relation is similar to that of the RAN-reading relation. A…

Empirical research investigating the association between teacher pay incentives and student test scores has grown rapidly over the past decade. To integrate the findings from these studies and help inform the debate over teacher merit pay, this meta-analysis synthesizes effect sizes across 37 primary studies, 26 of which were conducted in the…

Purpose: Promoting the labour integration of people with functional diversity is a key element to achieve their social inclusion. This meta-analysis aims to examine the effectiveness of experimental programs in developing employable skills for people with disabilities. Methods: Literature searches up to June 2019 were conducted in four databases…

This study examined the effect size of professional development programs on teachers' science teaching by meta-analysis method. For this purpose, literature review was made on existing national and international studies. In this context, master's thesis, doctoral dissertation, and articles conducted between 1990 and 2019 were appropriate for the…

Engagement in early childhood has been linked with later achievement, but the relation between these variables and how they are measured in early childhood requires examination. We estimated the overall association between academic engagement and achievement in children prior to kindergarten entry. Our systematic literature search yielded 13,521…

Background: Researchers debate whether game-based learning (GBL) affects students' achievement emotions, as past studies yielded mixed results. Objectives: This study determines the overall effect of GBL on students' positive achievement emotion and their negative achievement emotions (PAEs, NAEs), along with their moderators. Methods: This…

The most common and well-known meta-regression models work under the assumption that there is only one effect size estimate per study and that the estimates are independent. However, meta-analytic reviews of social science research often include multiple effect size estimates per primary study, leading to dependence in the estimates. Some…

Currently, masses of studies on mathematics learning getting to know have been discovered in numerous literatures supported by the use of blended learning model. This meta-analysis study aims at determining the overall effect of using blended learning. This study analyses 36 effect sizes from ERIC documents, Google scholar, and repositories from…

Tingir et al. (2017) concluded from their meta-analysis that the subject areas taught through mobile devices had significantly higher achievement scores (d = 0.48) than the ones taught with traditional teaching methods. Given the relatively high positive effect of mobile devices on student achievement, we carefully analysed the selected research…

Mixed-effects models can be used to examine the association between a categorical moderator and the magnitude of the effect size. Two approaches are available to estimate the residual between-studies variance, t[superscript 2][subscript res] --namely, separate estimation within each category of the moderator versus pooled estimation across all…
