The National Science Foundation-sponsored report "Fostering Learning in the Networked World" called for "a common, open platform to support communities of developers and learners in ways that enable both to take advantage of advances in the learning sciences." We review research on science inquiry learning environments (ILEs)…

This paper presents the first experimental evidence on the effects of live versus internet media of instruction. Students in a large introductory microeconomics course at a major research university were randomly assigned to live lectures versus watching these same lectures in an internet setting, where all other factors (e.g., instruction,…

The purpose of this paper is to provide a summary of evidence for the effectiveness and safety of commonly used crisis interventions in schools, such as critical incident stress debriefing (CISD), critical incident stress management (CISM), and psychological debriefing (PD). Two researchers independently searched relevant databases for reviews and…

Storm, Tressoldi, and Di Risio (2010) rely on meta-analyses to justify their claim that the evidence for psi is consistent and reliable. They manufacture apparent homogeneity and consistency by eliminating many outliers and combining databases whose combined effect sizes are not significantly different--even though these combined effect sizes…

Purpose: The present study is a meta-analysis that examines the difference in novel word learning performance between children with primary language impairment (LI) and typically developing children. Participant and task characteristics were examined as variables that potentially moderated children's word learning. Method: Eight hundred and…

Empirical evidence supports the efficacy of psychodynamic therapy. Effect sizes for psychodynamic therapy are as large as those reported for other therapies that have been actively promoted as "empirically supported" and "evidence based." In addition, patients who receive psychodynamic therapy maintain therapeutic gains and appear to continue to…

The authors conducted a qualitative meta-analysis of the research on assessment accommodations for students who are deaf or hard of hearing. There were 16 identified studies that analyzed the impact of factors related to student performance on academic assessments across different educational settings, content areas, and types of assessment…

The purpose of this article is to provide school psychologists with a synthesis of important information regarding the epidemiology, etiology, assessment, and treatment of childhood depression. A review of the recent research and relevant literature is summarized reflecting the contemporary knowledge regarding depression during childhood and…

The need for higher enrollment, along with a greater focus on educational access and making college more accessible has created an urgent need for community colleges and universities to develop retention and persistence strategies for students who are not prepared academically and may lack the resources to be successful in college (Bailey &…

This article reports a meta-analysis based on a multiple case study of the use of learning study (LS) to understand children's learning in Swedish preschool. The aim is to investigate whether and how the LS model can be developed, adjusted and used to meet contemporary demands placed upon preschool teachers for increased content focus and improved…

This meta-analysis is designed to build on the existing knowledge base by examining vocabulary interventions specifically for factors associated with child outcomes for at-risk children. Specifically, the authors addressed the following questions: (1) To what extent are vocabulary interventions an effective method for at-risk children prior to…

Despite the large research base grounded in behavioral theory for strategies to increase appropriate behavior and prevent or decrease inappropriate behavior in the classroom, a systematic review of multi-component universal classroom management research is necessary to establish the effects of teachers' universal classroom management approaches.…

When conducting a meta-analysis, it is common to find many collected studies that report regression analyses, because multiple regression analysis is widely used in many fields. Meta-analysis uses effect sizes drawn from individual studies as a means of synthesizing a collection of results. However, indices of effect size from regression analyses…

Historically, qualitative and quantitative approaches have been applied relatively separately in synthesizing qualitative and quantitative evidence, respectively, in several research domains. However, mixed methods approaches are becoming increasingly popular nowadays, and practices of combining qualitative and quantitative research components at…

One of the most influential studies affecting educational policy is Glass and Smith's 1978 study, "Meta-Analysis of Research on the Relationship of Class-Size and Achievement." Since its publication, educational policymakers have referenced it frequently as the justification for reducing class size. While teachers and the public had long believed…
