With the explosion of multimedia learning environments and the use of digital time-compression algorithms in common software and hardware, we need guidance on how to use this technology without sacrificing quality and learning outcomes. The purpose of the meta-analysis is to examine the existing empirical research literature to derive an overall…

This systematic review examined the effects of distinct physical activity interventions on the academic achievement of school students based on an analysis of four distinct outcomes: mathematics, language, reading, and composite scores. This study was performed in accordance with the PRISMA guidelines and the QUORUM statement. A literature search…

Clinicians, teachers, and researchers have long suspected that there may be some kind of association between poor reading and emotional health. However, for many years, studies of this association were generally sporadic and poor in quality. This article outlines how -- over the last 5 years or so -- national and international associates of the…

The study aims to portray the implementation of bilingual language policy and its implications for multiculturalism and internationalization of higher education. The meta-analysis research design enables the researchers in this study to search the available published public documents that are relevant for this study. The result of the study…

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…

Systematic reviews often encounter primary studies that report multiple effect sizes based on data from the same participants. These have the potential to introduce statistical dependency into the meta-analytic data set. In this paper, we provide a tutorial on dealing with effect size multiplicity within studies in the context of meta-analyses of…

Conducting mixed methods research studies has the potential to help researchers who represent special education to address relatively complex questions compared to monomethod research studies. Therefore, it is important to determine the prevalence of mixed methods research studies in special education, especially because the prevalence rate…

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…
