Multiple meta-analyses have now documented small positive effects of teacher professional development (PD) on pupil test scores. However, the field lacks any validated explanatory account of what differentiates more from less effective in-service training. As a result, researchers have little in the way of advice for those tasked with designing or…

The internship is a crucial component of principal preparation. This systematic research review aims to build on two prior syntheses of existing research on principal internships. We employed an exhaustive review of five search engines for empirical studies on principal internships in the United States between 2010 and 2023. Our search yielded 92…

Many teacher education researchers have expressed concerns about the lack of rigorous impact evaluations of teacher preparation practices. I summarize these various concerns as they relate to issues of internal validity, measurement, and external validity. I then assess the prevalence of these issues by reviewing 166 impact evaluations of teacher…

Clearinghouses set standards of scientific quality to vet existing research to determine how "evidence-based" an intervention is. This paper examines 12 educational clearinghouses to describe their effectiveness criteria, to estimate how consistently[underlined] they rate the same program, and to probe why their judgments differ. All the…

Although flipped classroom pedagogies have been widely touted for their ability to foster diverse 21st-century learning objectives, previous syntheses of flipped learning have focused almost exclusively on outcomes related to academic achievement. Using data from 317 studies, our research addresses this deficit by providing a comprehensive…

Teacher coaching has emerged as a promising alternative to traditional models of professional development. We review the empirical literature on teacher coaching and conduct meta-analyses to estimate the mean effect of coaching programs on teachers' instructional practice and students' academic achievement. Combining results across 60 studies that…

The purpose of this literature review is to systematically examine policy and practice intervention research and assess the impact of those interventions on high school dropout and school completion rates. This systematic review extends the literature by (a) describing both policy and practice interventions, (b) synthesizing findings from…

Ensuring an informed and effective dementia workforce is of international concern; however, there remains limited understanding of how this can be achieved. This review aimed to identify features of effective dementia educational programs. Critical interpretive synthesis underpinned by Kirkpatrick's return on investment model was applied. One…

The effectiveness of bilingual programs for promoting academic achievement of language minority children in the United States has been examined in six meta-analyses. The present meta-analytic study investigates this topic for the first time in the European context. Thorough literature searches uncovered 101 European studies, with only 7 meeting…

This meta-analysis examined which classroom management strategies and programs enhanced students' academic, behavioral, social-emotional, and motivational outcomes in primary education. The analysis included 54 random and nonrandom controlled intervention studies published in the past decade (2003-2013). Results showed small but significant…

To facilitate second language learning, it has become increasingly popular to use a second language as the medium of instruction for content subjects for majority language students. Although numerous research studies have shown the advantages of such kind of programs in North America and Europe, those investigating English as the Medium of…

Despite increasing emphasis on preparing more and better teachers and despite the near universal presence of student teaching across teacher education programs (TEPs), numerous questions about what and how student teaching experiences contribute to preservice teachers' development remain unanswered. Indeed, much of the attention focused on student…

High school exit exams are affecting a growing majority of high school students. Although exit testing polices were enacted with the goal of improving student achievement as well as postsecondary outcomes, they also have the potential for negative effects. To better understand the effects of exit testing policies, in this article the authors…

This article reviews research on the achievement outcomes of three types of approaches to improving elementary mathematics: mathematics curricula, computer-assisted instruction (CAI), and instructional process programs. Study inclusion requirements included use of a randomized or matched control group, a study duration of at least 12 weeks, and…
