After the fall of communist regimes in Central and Eastern Europe, the returns to education were substantially growing over time. We summarise the existing literature conducting a meta-analysis of returns to education for economies of Central and Eastern Europe (CEE) and test for several mechanisms, which can explain the evolution of the returns…

Confidence assessment (CA) involves students stating alongside each of their answers a confidence rating (e.g. 0 low to 10 high) to express how certain they are that their answer is correct. Each student's score is calculated as the sum of the confidence ratings on the items that they answered correctly, minus the sum of the confidence ratings on…

This study synthesized impacts of integrated literacy and content-area instruction (i.e., science, social studies) on vocabulary and comprehension outcomes in the elementary years (i.e., kindergarten through fifth grade). A systematic search of the extant literature identified 35 (quasi)experimental studies. Random-effects models were used to…

Background: Research shows that over summer break, students forget approximately 1 month of learning in math and reading; furthermore, low-income students lose ground relative to peers. Year-round education (YRE) redistributes schooldays to shorten summer. Prior analyses pooled single-track YRE (academic intervention in which all students attend…

Prenatal alcohol exposure (PAE) is associated with profound and lifelong disability. The umbrella term fetal alcohol spectrum disorder (FASD) describes a spectrum of impairments resulting from the deleterious effects of PAE (Chudley et al., 2005). While the core aspects of the condition remain unchanged, the Australian guidelines comprise two…

Case-mix heterogeneity across studies complicates meta-analyses. As a result of this, treatments that are equally effective on patient subgroups may appear to have different effectiveness on patient populations with different case mix. It is therefore important that meta-analyses be explicit for what patient population they describe the treatment…

The Hartung-Knapp method for random-effects meta-analysis, that was also independently proposed by Sidik and Jonkman, is becoming advocated for general use. This method has previously been justified by taking all estimated variances as known and using a different pivotal quantity to the more conventional one when making inferences about the…

Having surveyed the history and methods of meta-regression in a previous paper, in this paper, we review which and how meta-regression methods are applied in recent research syntheses. To do so, we reviewed studies published in 2016 across four leading research synthesis journals: "Psychological Bulletin," the "Journal of Applied…

Purpose: The aim of this study is to find in which conditions animation based teaching style for example teaching through 2D or 3D animations or animated diagrams leads to the better learning outcome. To achieve this purpose, we compared these two conditions (i) animation based teaching style is effective when offered to high spatial ability…

Previous meta-analyses on peer tutoring have mainly included studies using treatment-control/comparison design and excluded studies that adopted pre-test-post-test design. However, some recent meta-analyses on other interventions adopting pre-test-post-test design revealed that certain crucial intervention moderators should be considered when…

Open textbooks have been developed in response to rising commercial textbook costs and copyright constraints. Numerous studies have been conducted to examine open textbooks with varied findings. The purpose of this study is to meta-analyze the findings of studies of postsecondary students comparing learning performance and course withdrawal rates…

This systematic review, specifically a Meta-synthesis, aimed to synthesize the challenges and implementation of Inclusive Education (IE) in selected Asian countries. Fifteen (15) out of 792 studies were selected and screened through a set of inclusion and exclusion criteria. Academic databases such as Google Scholar, Cross Ref, Open Alex, and…

With the study reported on here we aimed to synthesise recent quantitative research to specify the effect of inclusive practices on attitudes via meta-analysis. Since attitudes have an integral role in the performance of inclusion programmes, within the scope of the study, the cumulative findings of experimental studies conducted on attitudes…

This meta-analysis synthesized the effects of the English medium instruction and content and language integrated learning (EMI-CLIL) approach on secondary-level students' English learning. The dataset included 44 samples (N = 7,434) from 38 primary studies. The results revealed EMI-CLIL's overall effectiveness for the development of English…

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…
