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…

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…

In a series of meta-analyses, paternal sensitivity was associated with children's (age range: 7 months-9 years) overall cognitive functioning (N = 3,193; k = 23; r = 0.19), including language skills (k = 9; r = 0.21), cognitive ability (k = 9; r = 0.18), and executive function (k = 8; r = 0.19). Paternal sensitivity was not associated with…

In multisite experiments, we can quantify treatment effect variation with the cross-site treatment effect variance. However, there is no standard method for estimating cross-site treatment effect variance in multisite regression discontinuity designs (RDD). This research rectifies this gap in the literature by systematically exploring and…

Elicited imitation tasks (EITs) have been proposed and examined as a practical measure of second language (L2) proficiency. This study aimed to provide an updated and comprehensive view of the relationship between EITs and other proficiency measures. Toward that end, 46 reports were retrieved contributing 60 independent effect sizes (Pearson's r)…

Fluent conversation requires temporal organization between conversational exchanges. By performing a systematic review and Bayesian multi-level meta-analysis, we map the trajectory of infants' turn-taking abilities over the course of early development (0 to 70 months). We synthesize the evidence from 26 studies (78 estimates from 429 unique…

Research has revealed the extent and mechanism of the relation between language (dominated by alphabetic systems) and students' mathematics learning, but when it comes to Chinese language (an orthographic system), nature remains elusive. In this meta-analysis we aim to quantify the size of the relation between Chinese language and mathematics and…
