Research on attention allocation to social and non-social stimuli in autism spectrum disorder (ASD) has produced mixed results, with some studies suggesting that attention allocation is atypical in ASD (e.g., Klin, Jones, Schultz, Vokmar, & Cohen, 2002) and others finding no significant differences in attention allocation patterns when…

The acquisition of a language is a complex process. Applied Linguistics research tends to view this process as classroom-based. It is only more recently that learners, in particular young learners, are being placed in the centre of investigation in research exploring language learning from their subjective perspectives. To understand these…

A recent national report heartily supported arts integration as an effective, innovative, and cost-efficient way to address teachers' and students' needs; however, the report called for a better understanding of when, for whom, and what content areas are best served by arts integration methods. The effectiveness of drama-based pedagogy (DBP), a…

ABRACADABRA (ABRA) is an evidence-based suite of interactive multimedia that engages learners in the development of core reading skills. This meta-analysis presents an update of the research evidence about the effectiveness of ABRA for elementary students. It reports 91 effect sizes in six reading-related outcomes for a sample of 7,388 students.…

The purpose of this meta-synthesis is to formulate a hypothesis concerning the importance of diacritical marks in Arabic word recognition for typically developed Arabic readers. I propose that the importance of diacritical marks in Arabic word recognition varies as a function of grade level, stimuli frequency, and text affiliation. Stimuli…

In meta-analysis, the random-effects model is often used to account for heterogeneity. The model assumes that heterogeneity has an additive effect on the variance of effect sizes. An alternative model, which assumes multiplicative heterogeneity, has been little used in the medical statistics community, but is widely used by particle physicists. In…

Meta-analyses in orphan diseases and small populations generally face particular problems, including small numbers of studies, small study sizes and heterogeneity of results. However, the heterogeneity is difficult to estimate if only very few studies are included. Motivated by a systematic review in immunosuppression following liver…

Introduction: Previous studies suggest that many systematic reviews contain meta-analyses that display temporal trends, such as the first study's result being more extreme than later studies' or a drift in the pooled estimate. We assessed the extent and characteristics of temporal trends using all Cochrane intervention reports published 2008-2012.…

In network meta-analysis, the use of fixed baseline treatment effects (a priori independent) in a contrast-based approach is regularly preferred to the use of random baseline treatment effects (a priori dependent). That is because, often, there is not a need to model baseline treatment effects, which carry the risk of model misspecification.…

This article argues that to better investigate the enduring relationship between social class background and inequalities in post-compulsory education necessitates a more comprehensive approach to thinking with Bourdieu, but also a need to move beyond his seminal, much used concepts. Through meta-analysis, we review how Bourdieusian theory has…

A common concern about the Beck Depression Inventory, Second edition (BDI-II) among researchers in the area of depression has long been the single-factor scoring scheme. Methods exist for making cross-sample comparisons of latent structure but tend to rely on estimation methods that can be imprecise and unnecessarily complex. This study presents a…

Former literature reviews suggested that if (student) teachers learn together in their professional development activities, professional development is enhanced. In the present literature review, we explored a variety of peer teacher professional development activities, conceptually divided into coaching, collaborating, and assessing activities.…

The relation between self-determination and intellectual functioning is complex, as other contextual factors may also play significant roles in explaining variability in self-determination. This study used meta-analytic techniques to assess how self-determination measures vary between people with disabilities classified as having intellectual…

This systematic review investigated one systematic approach to designing, implementing, and evaluating functional assessment-based interventions (FABI) for use in supporting school-age students with or at-risk for high-incidence disabilities. We field tested several recently developed methods for single-case design syntheses. First, we appraised…

Following on from successful early intervention programs abroad, the Netherlands also introduced a number of different programs to tackle educational disadvantage in preschool and early years education. Studies that investigate the effects of Dutch early childhood interventions have been published since 2000. This meta-analytic review study…
