We report on a meta-analysis designed to test the theory that instruction that involves direct teaching of academic vocabulary and teaching strategies to determine the meaning of unknown words develops students' abilities to infer new words' meanings and builds students' overall vocabulary knowledge. We meta-analyzed 39 experimental and…

Peer learning is a distinct category of student support gaining popularity globally and in South Africa, although these are typically informal approaches which have not been sufficiently researched to examine their influence and impact. Some scholars have criticised the available research as patchy, inconsistent, and methodologically weak.…

This meta-analysis determined game-based learning's (GBL) overall effect on students' computational thinking (CT) and tested for moderators, using 28 effect sizes from 24 studies of 2,134 participants. The random effects model results showed that GBL had a significant positive overall effect on students' CT (g = 0.677, 95% confidence interval…

Based on 52 studies with samples mostly from English-speaking countries, the current study used Bayesian network meta-analysis to investigate the intervention effectiveness of different reading comprehension strategy combinations on reading comprehension among students with reading difficulties in 3rd through 12th grade. We focused on commonly…

Which domain-specific self-evaluations are most central to children's global self-worth? And does this differ between countries with different levels of collectivism-individualism? We conducted a preregistered cross-cultural meta-analysis to address these questions. We included 141 independent samples (21 countries/regions, 584 cross-sectional…

Rising food and nutrition insecurity across the U.S. poses a significant health concerns. Despite the expansion of federal support and food aid programs, insecurity persists. This dissertation asks about the extent to which national funding initiatives and local emergency food organizations as mediated by the university-based agriculture Extension…

It was aimed to review the effect of the use of augmented reality applications on the academic achievement of students in science education in this study. In line with this aim, the experimental researches reviewing the effect of use of augmented reality applications within the scope of science course on student achievement were evaluated with…

A systematic review of the literature (1965-2022) and meta-analysis were undertaken to compare the school readiness skills of children participating in public pre-kindergarten (pre-K) or Head Start. Seven quasi-experimental studies met the inclusion criteria for the meta-analysis and 38 effect sizes were analyzed. Results indicated no reliable…

Multivariate meta-analysis, which jointly analyzes multiple and possibly correlated outcomes in a single analysis, is becoming increasingly popular in recent years. An attractive feature of the multivariate meta-analysis is its ability to account for the dependence between multiple estimates from the same study. However, standard inference…

Network meta-analysis (NMA) can be used to compare multiple competing treatments for the same disease. In practice, usually a range of outcomes is of interest. As the number of outcomes increases, summarizing results from multiple NMAs becomes a nontrivial task, especially for larger networks. Moreover, NMAs provide results in terms of relative…

Traditional visualization in meta-analysis uses forest plots to illustrate the combined treatment effect, along with the respective results from primary trials. While the purpose of visualization is clear in the pairwise setting, additional treatments broaden the focus and extend the results to be illustrated in network meta-analysis. The…

Fourteen empirical studies on academic burnout were synthesized and reviewed with a meta-analytic approach based on the framework of job demand, control, support model. It was found that demand, control, and support were associated with academic burnout. The three dimensions of burnout were negatively related to demand and positively related to…

This meta-analysis assessed the effect of word-problem-solving interventions on the word-problem-solving accuracy of students identified as having a learning disability (LD) or at risk for an LD in kindergarten to the sixth grade. Eighteen randomized control group designed studies met the inclusion criteria. Overall, word-problem-solving…

The etiological significance of neurological disorders in autism is debated, but it is clear that they complicate support provision and clinical management, and can have negative impact on outcomes. This systematic review and meta-analysis explored the full range of co-occurring neurological disorders in autism. We estimated the odds of having…

Achievement goal theory is a popular theoretical framework that has been widely used to understand the goals students hold regarding their academic work. This theoretical model has been subject to an ongoing debate regarding the number and nature of constructs it includes. Notable in such debates has been the inclusion or exclusion of…
