Despite decades of research, it has been difficult to achieve consensus on a definition of common learning disabilities such as dyslexia. This lack of consensus represents a fundamental problem for the field. Our approach to addressing this issue is to use model-based meta-analyses and Bayesian models with informative priors to combine the results…

The relationship between creativity and symbolic immortality had been long acknowledged by scholars. In a review of the literature, we found 12 papers that empirically examined the relationship between creativity and mortality awareness using a Terror Management Theory paradigm, overall supporting the notion that creativity plays an important role…

This meta-analytic study examined the validity of Gordon's music aptitude tests as predictors of other musical variables. The four tests analyzed were the Music Aptitude Profile (1965), Primary Measures of Music Audiation (1979), Intermediate Measures of Music Audiation (1982), and Advanced Measures of Music Audiation (1989). Separate analyses…

High-quality, use-oriented, and well-communicated research can improve social outcomes in low- and middle-income countries and, by doing so, accelerate development progress. We provide a meta-analysis of research supported by Canada's International Development Research Centre. We use a large and unique data set that comprises 170 research studies…

Formal empirical assessments of replication have recently become more prominent in several areas of science, including psychology. These assessments have used different statistical approaches to determine if a finding has been replicated. The purpose of this article is to provide several alternative conceptual frameworks that lead to different…

Research synthesis is the practice of systematically distilling and integrating data from many studies in order to draw more reliable conclusions about a given research issue. When the first edition of "The Handbook of Research Synthesis and Meta-Analysis" was published in 1994, it quickly became the definitive reference for conducting…

This meta-analysis study synthesizing the results of experimental and quasi experimental studies examined the effects of self-assessment interventions on student academic performance from primary education to higher education. A total of 16 studies with 46 effect sizes involving more than 7,650 participants were included in the analysis. Research…

This meta-analysis explores the correlation between self-assessment (SA) and language performance. Sixty-seven studies with 97 independent samples involving more than 68,500 participants were included in our analysis. It was found that the overall correlation between SA and language performance was 0.466 (p < 0.01). Moderator analysis was…

Flipped classroom has become a popular buzzword in the post-secondary education setting, and it is one of the most visible trends in smart learning environments. Alongside this popularisation comes the view that the flipped classroom is something desirable. Yet, many educators remain divided over whether flipped classroom is really an improvement…

Research self-efficacy represents the adaptation of the social cognitive concept of self-efficacy to the field of academic and scientific research and is one of the best predictors of successfully engaging in research activities. The current meta-analysis focuses on the relationship between research self-efficacy and 14 other relevant variables…

Currently, the research on the overall effect of flipped instruction on K-12 students' academic achievement has been insufficient, especially across various subject areas and grade levels. To redress this research gap, this study first synthesised five aspects of research on flipped instruction, including theoretical underpinnings, application…

Using a meta-review approach organized historically in relation to critical policy incidents, this paper critically reviews the process of developing and (re) invigorating Environment and Sustainability Education (ESE) (policy) research "as ESE policy" engagement over a 30+ year period in a rapidly transforming society, South Africa. It…

School voucher programs are scholarship initiatives -- frequently government funded or incentivized -- that pay for students to attend private schools of their choice. This study is the first formal meta-analytic consolidation of the evidence from all randomized controlled trials (RCTs) evaluating the student-level math and reading test score…

With the development of Web 2.0 technologies, the studies conducted in this field are diversifying and quite different results are obtained. In the current study, the contributions of wikis and blogs, which are considered as web 2.0 technologies, to academic performance were examined with meta-analysis method. The studies following…

A meta-analysis is a statistical method for combining the results of primary studies on the same topic. Meta-analyses play a significant role in scientific research particularly in the field of gifted education in which the study results rely on small samples, imprecise measurements, and heterogeneity. This overview provides a thematic analysis…
