Toward the goal of more rapid knowledge accumulation via better meta-analyses, this article explores statistical approaches intended to increase the precision and comparability of effect sizes from education research. The featured estimate of the proposed approach is a standardized mean difference effect size whose numerator is a mean difference…

This study aims to comparatively analyze the effect size of perceptions related to democratic attitudes and values of school administrators, teachers, preservice teachers, and students. The meta-analysis method, one of the research synthesis methods, was used in the research. Within the scope of the study, master's and doctoral theses and research…

Today, hundreds of studies on the technique known as Realistic Mathematics Education (RME) have been discovered. Numerous trials yielding contradicting results. The purpose of this meta-analysis is to ascertain the overall effect of RME and to examine the moderator variables in order to explore the consequences. The ERIC database, Sage…

Students' self-determined motivation (acting out of interest, curiosity, and abiding values) is associated with higher academic well-being, persistence, and achievement. Self-determination theory posits that self-determined motivation is dependent on the satisfaction of three psychological needs (relatedness, competence, and autonomy), which are…

The purpose of this study was to estimate the overall reliability values for the scores produced by Runco Ideational Behavior Scale (RIBS) and explore the variability of RIBS score reliability across studies. To achieve this, a reliability generalization meta-analysis was carried out using the 86 Cronbach's alpha estimates obtained from 77 studies…

The purpose of this study was to synthesize experimental studies that explain the effect of student-centered methods and techniques used in primary school mathematics courses on academic achievement. Some certain criteria were selected and applied regarding the inclusion of primary study in the synthesis. As a result of qualitative systematic…

The research emphasized three main objectives: 1) to analyze the propensity score of the research effect size for developing students' creative thinking, 2) to study the attribute variables effect of the research on the effect size of creative thinking before and after the propensity score adjustments, and 3) to compare the effect size between…

While an increasing number of studies have cast light on the effectiveness of MALL (mobileassisted language learning) on English as a foreign/second language (EFL/ESL) reading comprehension, there is still a lack of comprehensive meta-analysis regarding the effect sizes of these studies. To fill the gap, this study reported results based on a…

Due to their experience of managing two languages, it has been suggested that bilinguals could receive more practice in the domain of working memory (WM) leading to a WM bilingual advantage. Although some studies have shown that bilinguals can outperform monolinguals in WM tasks, the studies investigating WM capacity in bilinguals provide…

Impact evaluation and measurement are highly complex and can pose challenges for both social impact providers and funders. Measuring the impact of social interventions requires the continuous exploration and improvement of evaluation approaches and tools. This article explores the available evidence on meta-evaluation--the "evaluation of…

Examining gender differences in learning is of critical importance in terms of revealing any potential inequalities. Although gender differences in lifelong learning tendencies are often examined in individual studies in the literature, the relevant findings are found to be inconsistent. In this study, a meta-analysis was carried out to…

Guided by the self-system process model, the aim of this study was to unravel the relationship between students' perceived teacher support and academic achievement as well as to address the role of student engagement, using a meta-analytic approach. Based on 71 empirical articles, we found that there was a small to medium correlation between…

Improving self-efficacy in the learning process of Mathematics is very important as the key to success in learning Mathematics. Self-efficacy in learning mathematics is a belief in one's ability to solve mathematical problems. Many studies have been conducted on the relationship between self-efficacy and students' mathematics learning ability in…

Since individuals with intellectual disabilities are vulnerable to injury, they should be aware of potential dangers and develop skills to protect themselves from possible injury. This study verifies the effects of group safety skill training on individuals with intellectual disabilities. Meta-analytical procedures were used to identify and…

Systematic reviews and meta-analyses are important techniques because they synthesize results from multiple primary studies on a similar topic. To influence policy, practice, and research, however, synthesis researchers must translate the results for various audiences. Ideally, the translation drives future research agendas, informs policymaking,…
