The United States Chairman of the Joint Chiefs of Staff declared critical thinking as a capability imperative for Force XXI. He directed Military Services to develop critical thinkers. There is limited evidence of success in terms of developing critical thinking abilities. Specifically, the U.S. Army lacks a single, generally accepted, codified…

The study explores the effectiveness of multimodality teaching using the 4MAT Model. A meta-analysis was conducted with empirical studies on instruction via multimodality teaching in preschool, K-12, and higher education. The studies in the meta-analysis involved an experimental and control group. The control group received traditional teaching…

This mixed methods study investigates the research on strategies for distance learning to identify best practices for distance teaching of secondary students. For this study, distance learning was defined as an organized educational experience that takes place either synchronously or asynchronously while the student is in a different physical…

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…

Amid ongoing conflicts globally, the number of refugees has continued to grow, and half of them are children. Education not only stands as a fundamental human right for refugees but also as a vital pathway for their integration and resettlement in the future. Thus, refugee education prioritizes quality education for refugee learners within their…

Over the last four decades, meta-analysis has proven to be a vital analysis strategy in educational research for synthesizing research findings from different studies. When synthesizing studies in a meta-analysis, it is common to assume that the true underlying effect varies from study to study, as studies will differ in design, participants,…

This three-article format dissertation aims to provide evidence of the effect size of the relationship between writing self-efficacy and writing achievement in an empirical study and a meta-analysis, and compare three methods, the averaging method, three-level meta-analysis (3LM), and robust variance estimation (RVE), in handling multiple…

This dissertation describes a program of research encompassing three studies that focused on examining the effects of enhanced expectancies and perceptions of success on motor learning. OPTIMAL theory (Wulf & Lewthwaite, 2016) proposes that practice manipulations that enhance a learner's expectations for future successful outcomes lead to…

The purpose of this meta-analysis was to investigate the effectiveness of the use of games as part of mathematics instruction on academic achievement in grades Kindergarten to 12 in the United States. There were 17 studies selected for investigation published from 2010 to 2023 that focused on game-based learning and mathematics. This meta-analysis…

More than 85% of federally funded research initiatives fail to produce significant positive results (Coalition for Evidence-Based Policy, 2013). Moreover, of the less than 15% that do yield positive results, none show replicability outside of their original setting (Pogrow, 2017; Kizilcec et al., 2020). Mixed results are present in even the most…

This meta-analysis synthesized research on gender gap in the Force Concept Inventory (FCI). The main goal of the present meta-analysis was to identify the moderator variables that mediate effect size differences. Furthermore, the statistical significance of the average effect sizes was investigated. The inclusion criteria for the meta-analysis…

It is estimated that 16% of men and 26% of women have experienced child sexual abuse (CSA), and studies have shown a strong association with long-term psychosocial consequences. The use of psychoeducational groups with survivors of CSA has been found to produce favorable outcomes; however, no meta-analyses have been conducted on studies assessing…

This study examined the relationship of Problem-based Learning (PBL) and medical students' attitudinal behavior and academic outcomes. The analyses of 14 independent, primary studies conducted between 2003-2016, on 4,981 medical students across various medical schools were included in the study. The data were examined using a meta-analysis…

The research-to-practice gap in special education refers to educators' limited use of practices that are supported by empirical evidence. Procedures specifying criteria for the determination of evidence-based practices (EBPs) in special education have the potential to address challenges associated with identifying EBPs. Although meta-analyses and…

Research has been conducted to identify and analyze how schools are determining that the activities of their Professional Learning Community (PLC) are directly tied to student achievement as there is currently a gap in the existing literature with regards to this topic. For the purpose of this study, a "successful" PLC was defined as one…
