Research synthesis, eg, by meta-analysis, is more and more considered in the area of high-dimensional data from molecular research such as gene and protein expression data, especially because most studies and experiments are performed with very small sample sizes. In contrast to most clinical and epidemiological trials, raw data are often…

Multilevel meta-analysis is an innovative synthesis technique used for the quantitative integration of effect size estimates across participants and across studies. The quantitative summary allows for objective, evidence-based, and informed decisions in research, practice, and policy. Based on previous methodological work, the technique results in…

This study reviews the European evidence on the impact of professional development (PD) of pre-school educators on child outcomes. A meta-analysis investigates how PD of pre-school educators in formal pre-school centers in Europe affects child outcomes. The European studies are quite recent and limited in numbers, and our results show a…

In this study, the effectiveness of the learning stations technique and experimental investigations are tested by comparing this method to the traditional teaching method. A meta-analytical impact analysis method was used to calculate the effect size of the learning stations technique on academic achievement. Studies conducted in Turkey between…

Experiential learning activities have been used for over 40 years with the hope that they increase students learning. However, a definitive study that showed their overall effectiveness has not been produced. The purpose of this study is to address this gap in the literature. This meta-analysis examined a 43-year span and identified 13,626 journal…

Even though teachers are key figures of a program's effectiveness, most intervention studies have not focused explicitly on the effects of antibullying programs at teacher level. We conducted a meta-analysis into the effects of school-based antibullying programs on determinants of teacher intervention, including teachers' attitudes towards…

In the past 50 years, the original McMaster PBL model has been implemented, experimented, revised, and modified, and is still evolving. Yet, the development of PBL is not a series of success stories, but rather a journey of experiments, failures and lessons learned. In this paper, we analyzed the meta-analyses and systematic reviews on PBL from…

Blended instruction integrating off-line and on-line teaching has become an important instrument for promoting educational reform and innovation. However, the results of current empirical studies diverge on the effect of blended instruction on student performance, which necessitates further research on the effectiveness of blended instruction and…

Best instructional methods are essential tools to bring desirable changes in pre-service science teachers. The available literature lacks enough meta-analytic review illustrating the effect of various instructional methods on pre-service science teachers' learning outcomes. This meta-analytic review identified instructional methods used for…

The use of social media such as Twitter has gained popularity in education during the COVID-19 pandemic. This study included 22 high-quality peer-reviewed journal articles for the meta-analysis. The authors reveal that there are no significant differences in teaching effectiveness between the Twitter and non-Twitter-assisted learning approaches.…

There has been extensive research using centrality measures in educational settings. One of the most common lines of such research has tested network centrality measures as indicators of success. The increasing interest in centrality measures has been kindled by the proliferation of learning analytics. Previous works have been dominated by…

Although technology has increased our capacity for social networking both in the digital space and face-to-face, Kira J. Baker-Doyle contends that most professional development opportunities for educators are still fundamentally asocial. She calls for the adoption of humanizing network practices to create meaningful continuing education…

Inequality in reading outcomes is perhaps the single greatest social justice issue faced by school psychologists, and school psychologists need a better understanding of reading theory and its application to intervention to better combat the important issue. The present study examined the active view of reading (AVR; Duke & Cartwright, 2021),…

This study addresses a gap in the literature regarding the implementation of digital strategies in educational institutions, particularly universities. Despite significant advancements in the development of digital strategies, there remains a lack of commitment and vision for their effective implementation. This study systematically reviewed the…

Percentage study weights in meta-analysis reveal the contribution of each study toward the overall summary results and are especially important when some studies are considered outliers or at high risk of bias. In meta-analyses of test accuracy reviews, such as a bivariate meta-analysis of sensitivity and specificity, the percentage study weights…
