The paper has three major objectives. The first objective of the paper is to synthesize and define common categories of meta-analysis. The second objective is to propose a way to comprehend these common categories of meta-analysis through learning from their respective generic conceptual frameworks. The third objective is to point out which R…

Meta-analyses of educational research findings frequently involve statistically dependent effect size estimates. Meta-analysts have often addressed dependence issues using ad hoc approaches that involve modifying the data to conform to the assumptions of models for independent effect size estimates, such as by aggregating estimates to obtain one…

Diffraction has emerged as a concept and methodology through opposing reflexivity. In this paper, I argue that reflexivity and diffraction are not external to each other. In contrast, I propose that they blur into each other and so we do not find ourselves using pure reflexivity or diffraction. Furthermore, I contend that categorically…

A common problem in the analysis of multiple data sources, including individual participant data meta-analysis (IPD-MA), is the misclassification of binary variables. Misclassification may lead to biased estimators of model parameters, even when the misclassification is entirely random. We aimed to develop statistical methods that facilitate…

This research aims to prove and find out the influence of local wisdom-based learning media on the character of students in Indonesia. This research uses a quantitative method with a meta-analysis approach. The research data were analyzed using the 0.8.5 version of JASP software. The eligibility criteria used include: (a) The publications must be…

This systematic review addressed the following question: Which are the relations between L1 and/or L2 foundational and upper-level language skills, cognitive skills, high-order cognitive and self-regulation factors and L2-English reading comprehension skills in 11-to-19 year EFL secondary school students with different L1 language profiles?…

The 0.05 boundary within Null Hypothesis Statistical Testing (NHST) "has made a lot of people very angry and been widely regarded as a bad move" (to quote Douglas Adams). Here, we move past meta-scientific arguments and ask an empirical question: What is the psychological standing of the 0.05 boundary for statistical significance? We…

Theories of reading comprehension have widely predicted a role for syntactic skills, or the ability to understand and manipulate the structure of a sentence. Yet, these theories are based primarily on English, leaving open the question of whether this remains true across typologically different languages such as English versus Chinese. There are…

Mixed-effects models can be used to examine the association between a categorical moderator and the magnitude of the effect size. Two approaches are available to estimate the residual between-studies variance, t[superscript 2][subscript res] --namely, separate estimation within each category of the moderator versus pooled estimation across all…

The Learning and Study Strategies Inventory (LASSI; Weinstein et al., "Learning and study strategies inventory." H&H Publishing, 1987) is a prominent instrument used in thousands of institutions worldwide as an educational and research tool. Despite its widespread prevalence, there are inconsistencies regarding the underlying latent…

This meta-synthesis study aims to reveal the types of bilingualism in Turkey by interpreting the quantitative data and findings obtained from studies on bilingualism types. In the light of the findings, 28 types of bilingualism and 5 classification criteria have been identified in the theses written on bilingualism in the "Turkish Higher…

Literature reviews allow education professionals to identify effective interventions and assess trends in research and practice. However, issues with transparency and the specific methods used in conducting literature searches have the potential to limit the utility of reviews. This study evaluated the description of article search procedures and…

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 study set out to investigate the relationship between L2 vocabulary knowledge (VK) and second-language (L2) reading/listening comprehension. More than 100 individual studies were included in this meta-analysis, which generated 276 effect sizes from a sample of almost 21,000 learners. The current meta-analysis had several major findings.…

Feedback is one of the most important factors for successful learning. Contemporary computer-based learning and testing environments allow the implementation of automated feedback in a simple and efficient manner. Previous meta-analyses suggest that different types of feedback are not equally effective. This heterogeneity might depend on learner…
