Background: By 2009, 99% of U.S. classrooms had access to computers, with an average ratio of 1.7 students per computer, and 40% of teachers report using computers often in their classrooms. However, while K-12 schools are investing more heavily in digital technologies, only a small fraction of this investment is going to instructional software…

The purpose of this study was to conduct a meta-analysis of dissertation research that examined the implementation of professional learning communities (PLCs) and student achievement in preK-12 schools. An exhaustive search for such unpublished studies was conducted using the following criteria: 1) the studies were available on dissertation…

At the onset of the 21st century, the United States ushered in a new era of school accountability and reform with the No Child Left Behind Act [NCLB] (United States Department of Education, 2010). Until and unless it is repealed or replaced, this law continues in effect today, with many states now applying to renew their NCLB waivers (Klein,…

The common practice of using of guided notes in the K-12 and special education classroom is not fully appreciated or understood. In an effort to add to the existing research about this phenomenon, the current investigation expands on previously published research and one previously published meta-analysis that examined the impact of guided notes…

Peer management intervention is a subtype of peer-mediated intervention that involves training individuals to implement standardized intervention protocols to modify the behavior of their peers. This meta-analysis of single-case research synthesized the results of 29 studies examining the effectiveness of school-based peer management…

The history of research on interventions for struggling readers in Grades 4 through 12 dates back to 19th-century case studies of seemingly intelligent children who were unable to learn to read. Physicians, psychologists, educators, and others were determined to help them. In the process, they launched a century of research on a wide variety of…

This article reports on the results of a representative sample meta-analysis that explored the effects of interactive versus didactic pedagogy using computer-assisted instruction on measures of academic achievement. A systematic literature search revealed 40 studies, from which 55 effect sizes were extracted. The random effects model of analysis…

Four figures and three tables are appended.There is growing consensus among researchers, educators, and policy makers about the need for greater emphasis on ambitious student-centered mathematics instruction in light of mounting concern about student mathematics performance in the intermediate grades and beyond. To facilitate educators' adoption…

The present review examines research on the effects of educational technology applications on mathematics achievement in K-12 classrooms. Unlike previous reviews, this review applies consistent inclusion standards to focus on studies that met high methodological standards. In addition, methodological and substantive features of the studies are…

Background: Historically, significant advances in scientific understanding have followed advances in measurement and observation. As the resolving power of an instrument increased, so have gains in the understanding of the phenomena being observed. Modern interactive systems are potentially the new "microscopes" when they are…

The purpose of this study was to examine the relationship of specific cognitive abilities and reading comprehension across a variety of norm referenced tests that align with Cattell-Horn-Carroll (CHC) theory of cognitive abilities and integrative models of reading. Data from existing studies was analyzed by comparing the relationships of four…

We conducted a meta-analysis on the effectiveness of cooperative and collaborative learning to support enhanced literacy outcomes. Interventions considered were provided in regular education settings (i.e., not pull-out instruction) with students from Grades 2 through 12. Reviewing more than 30 years of literacy research, we located 18…

The purpose of this article is to present the findings of a qualitative metasynthesis focused on Black learners negotiating their mathematics experiences in multiple settings (in school and out-of-school) and reflecting on experiences that contributed towards their mathematics identities over time. Five findings emerged from this qualitative…

Giving a student control over their learning has theoretical and intuitive appeal, but its effects are neither powerful nor consistent in the empirical literature base. This meta-analysis updated previous meta-analytic research by Niemiec, Sikorski, and Walberg by studying the overall effectiveness of providing learner control within educational…

This article summarises findings from systematic reviews of research on primary and secondary mathematics, primary and secondary reading, and programmes for struggling readers. All reviews used a common set of procedures, requiring comparisons with control groups and duration of at least 12 weeks. Across hundreds of qualifying studies, a clear…
