Diversity and mobility in education and work present a paramount challenge that needs better conceptualization in educational theory. This challenge has been addressed by educational scholars with the notion of "boundaries", particularly by the concepts of "boundary crossing" and "boundary objects". Although studies on boundary crossing and…

Although connectionist models provide a framework explaining how the decoding and encoding abilities work reciprocally to enhance reading and spelling ability, encoding instruction in today's schools is not a priority. Although a limited amount of high-quality experimental or control studies to date (N = 11) give empirical support to using direct,…

Recent randomized experiments have found that seemingly "small" social-psychological interventions in education--that is, brief exercises that target students' thoughts, feelings, and beliefs in and about school--can lead to large gains in student achievement and sharply reduce achievement gaps even months and years later. These interventions do…

This review critically examines 15 empirical studies, conducted since the mid-1980s, on the effects of support, guidance, and orientation programs--collectively known as induction--for beginning teachers. Most of the studies reviewed provide empirical support for the claim that support and assistance for beginning teachers have a positive impact…

The "underclass" debate of the 1980s often concerned the relative importance of neighborhood racial and economic isolation to the educational challenges facing many African Americans. This review organizes the neighborhood effects research that has emerged since that time according to these differing perspectives. The review's triangulated…

Despite increased focus on the effects of organized activities on youth development, there is currently no consensus about the best way to assess various dimensions of involvement. This article explores the complexities of assessing involvement and focuses specifically on the following organized activity dimensions: (a) breadth, (b) intensity, (c)…

Extended time is one of the most common testing accommodations provided to students with disabilities. It is also controversial; critics of extended time accommodations argue that extended time is used too readily, without concern for how it changes the skills measured by tests, leading to scores that cannot be compared fairly with those of other…

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…

The goal of scientific literacy has led to a steady increase in argument-based interventions in science education contexts. It has been suggested that student participation in argument develops communication skills, metacognitive awareness, critical thinking, an understanding of the culture and practice of science, and scientific literacy.…

Attention has been directed toward extended school time as a measure to improve academic achievement. The school year and day length have varied over time and across localities depending on the particular needs of the community. Proponents argue that extending time will have learning and non-academic benefits. Opponents suggest increased time is…

Many of the democratizing opportunities provided by community colleges are diminished in the eyes of policy makers by inadequate rates of success. In particular, large proportions of students who enter community colleges do not persist for longer than a semester, complete a program, or attain a credential. This review critically examines academic…

This systematic review of algebra instructional improvement strategies identified 82 relevant studies with 109 independent effect sizes representing a sample of 22,424 students. Five categories of improvement strategies emerged: technology curricula, nontechnology curricula, instructional strategies, manipulatives, and technology tools. All five…

This meta-analysis examines the effects of vocabulary interventions on pre-K and kindergarten children's oral language development. The authors quantitatively reviewed 67 studies and 216 effect sizes to better understand the impact of training on word learning. Results indicated an overall effect size of 0.88, demonstrating, on average, a gain of…

Digital communication has transformed literacy practices and assumed great importance in the functioning of workplace, recreational, and community contexts. This article reviews a decade of empirical work of the New Literacy Studies, identifying the shift toward research of digital literacy applications. The article engages with the central…

A number of studies have documented the cognitive outcomes associated with bilingualism. To gain a clear understanding of the extent and diversity of these cognitive outcomes, the authors conducted a meta-analysis of studies that examined the cognitive correlates of bilingualism. Data from 63 studies (involving 6,022 participants) were extracted…
