American educational policy was rapidly transformed between 1980 and 2001. Accountability was introduced into a sphere that had long been loosely coupled, both major political parties reevaluated longstanding positions, and significant institutional control over the schooling shifted to the federal government for the first time in the nation's…

Based on interview data from a collective case study, this article uses current notions of racial microaggressions to explore this "subtle" racism through the voices of six Latino/a students as they transition to a predominantly White university. Using critical race theory as a framework, I argue for greater understanding and increased use of the…

Mathematics Recovery (MR) is designed to identify first graders who are struggling in mathematics and provide them with intensive one-to-one tutoring. We report findings from a 2-year evaluation of MR conducted in 20 elementary schools across five districts in two states. The design allowed for the estimation of the counterfactual growth…

Considerable attention has been devoted to the resegregation of public schools over the 1990s. No research to date, however, has examined change in school segregation since 2000. Using the National Center for Education Statistics (NCES) Common Core of Data (CCD), we examine longitudinal trends in racial/ethnic segregation in 350 U.S. metropolitan…

This article considers whether the socioeconomic diversity of the undergraduate student body and experiences with cross-class interaction (CCI) are significantly related to cross-racial interaction (CRI) and engagement with curricular/co-curricular diversity (CCD) activities. Individual students who reported higher levels of CCI had significantly…

Current theories of novice teacher learning have not accounted for the varied influences of pedagogical training, subject matter knowledge, tools, identity, and institutional context(s) on the development of classroom practice. We examined how 26 beginning secondary science teachers developed instructional repertoires as they participated in two…

This article analyzes the longitudinal development of differences in academic skills between children of Turkish origin and children of native-born German parents from age 3 to 6 in Germany with a focus on the role of immigrant parents' acculturation to the receiving society. Growth curve models show that Turkish-origin children start with lower…

Research on social capital in education rarely considers how the resources students can access through their friendships affect educational outcomes later in life. Using the National Longitudinal Study of Adolescent Health, we explore how having resource-rich best friends impacts adolescents' college completion. We compare the influence of…

The underrepresentation of girls from nondominant backgrounds in the sciences and engineering continues despite recent gains in achievement. This longitudinal ethnographic study traces the identity work that girls from nondominant backgrounds do as they engage in science-related activities across school, club, and home during the middle school…

Validating the structure of informal numeracy skills is critical to understanding the developmental trajectories of mathematics skills at early ages; however, little research has been devoted to construct evaluation of the Numbering, Relations, and Arithmetic Operations domains. This study was designed to address this knowledge gap by examining…

Tree thinking involves using cladograms, hierarchical diagrams depicting the evolutionary history of a set of taxa, to reason about evolutionary relationships and support inferences. Tree thinking is indispensable in modern science. College students' tree-thinking skills were investigated using tree (much more common in professional biology) and…

International doctoral students in the United States face challenges of acculturation in academia yet complete graduate school at higher rates and more quickly than their domestic counterparts. This study examined advisor support, sense of belonging, and academic self-concept among international and domestic doctoral students at a research…

A district-level reform model created by the Center for Data-Driven Reform in Education (CDDRE) provided consultation with district leaders on strategic use of data and selection of proven programs. Fifty-nine districts in seven states were randomly assigned to CDDRE or control conditions. A total of 397 elementary and 225 middle schools were…

In a 9-month training experiment, 64 first graders with a risk factor were randomly assigned to computer-assisted structured discovery of the add-1 rule (e.g., the sum of 7 + 1 is the number after "seven" when we count), unstructured discovery learning of this regularity, or an active-control group. Planned contrasts revealed that the add-1…

Using a cluster randomized trial design, we evaluated the persistence of effects of a research-based model for scaling up educational interventions. The model was implemented in 42 schools in two city districts serving low-resource communities, randomly assigned to three conditions. In pre-kindergarten, the two experimental interventions were…
