Systematic reviews and meta-analyses are important techniques because they synthesize results from multiple primary studies on a similar topic. To influence policy, practice, and research, however, synthesis researchers must translate the results for various audiences. Ideally, the translation drives future research agendas, informs policymaking,…

Background/Context: Methodological background: Meta-analysis typically depends on the assumption that true effects follow the normal distribution. While assuming normality of effect "estimates" is often supported by a central limit theorem, normality for the distribution of interventions' "true" effects is a computational…

Following the theme of the first two presentations, this presentation will focus on the choices available for research synthesis when summarizing research evidence. The presenters will describe the current research synthesis practice of the What Works Clearinghouse (WWC) as well as several alternative models, including inverse-variance weighted…

This article presents a meta-synthesis review of quality of online education (QOE) measurement approaches. In order to survey the existing body of knowledge, a qualitative method was employed to investigate what quality of online education is comprised of and how the concept has been measured through the literature. To achieve this, a total of 112…

During the past two decades, the Geoscience Education Research (GER) community has been increasingly recognized as an evidence-based research subdiscipline in the geoscience and in the larger discipline-based education research (DBER) field. Most recently, the GER community has begun to address the current state of the field and discuss the best…

This article provides a meta-analysis of research conducted on distributed leadership from 2002 to 2013. It continues the review of distributed leadership commissioned by the English National College for School Leadership (NCSL) ("Distributed Leadership: A Desk Study," Bennett et al., 2003), which identified two gaps in the research…

This paper reviews, analyzes, and reflects upon two important reports released in 2013, both discussing research evidence for the value of dance education or arts education more generally, among school-aged students. One report was created by a large dance education advocacy and support group in the USA, the National Dance Education Organization;…

Single-case design (SCD) research focuses on finding powerful effects, but the influence of this methodology on the evidence-based practice (EBP) movement is questionable. Meta-analytic procedures may help facilitate the role of SCD research in the EBP movement, but meta-analyses of SCDs are controversial. The current article provides an…

The Circle of Security™ interventions are psychosocial treatments intended to increase maternal sensitivity and thus child attachment security in infants and young children. A small number of publications have reported empirical research on outcomes of these treatments. This article reviews the research evidence, plausibility, theoretical…

Evidence-based practices (EBPs) are supported as generally effective for populations of learners by bodies of high-quality and experimental research and, when aligned with stakeholder values and practical needs, should be prioritized for implementation. However, evidence-based practices are not currently available for all learner types in all…

Poor quality early childhood education and care (ECEC) can be detrimental to the development of children as it could lead to poor social, emotional, educational, health, economic, and behavioural outcomes. The lack of consensus as to the strength of the relationship between teacher qualification and the quality of the early childhood learning…

This chapter summarizes a set of research studies that focus on high school course offerings, takings, and effects. Improving high school experiences and having students graduate from high school ready for college are national priorities under President Obama's Race to the Top initiative. Doing so by expanding access to advanced courses dates back…

This study examined interventions for addition and subtraction that were implemented through single-case design (SCD) research studies. We attempted to extend prior SCD meta-analyses by examining differences in effect sizes across several moderating variables and by including a novel index of effect, improvement rate difference (IRD). We also…

Virtual schools have the potential to improve student learning--but so far, as asserted in this article, research tells little about how online instruction affects student performance. Most of the studies that pointed to good student outcomes were small in scale and based on specific programs or products. Few provide data to help understand…

Over the last 4 decades, the school effectiveness and school improvement research bases have gained prominence and recognition on the international stage. In both a theoretical and empirical sense, they have matured through a wide range of well-documented projects, interventions, and innovations across a range of countries, describing how efforts…
