The present study tests two predictions stemming from the hypothesis that a source of difficulty with rational numbers is interference from whole number magnitude knowledge. First, inhibitory control should be an independent predictor of fraction understanding, even after controlling for working memory. Second, if the source of interference is…

Measures of school-level growth in student outcomes are common tools for assessing the impacts of schools. The vast majority of these measures use standardized tests as the outcome of interest, even though emerging evidence demonstrates the importance of social-emotional learning (SEL). In this article, we present results from using the first…

This article examines four preadolescent girls' physical lives over three years inside and outside of schools (fourth, fifth, and sixth grades). The girls participated in a school-based physical education intervention during the first two years that was designed to enhance their physical activity (PA) choices in both environments. At the…

In this report, the authors present the results of a long-term tracking study that follows 1,177 students who applied to enter 1 of 13 oversubscribed Knowledge Is Power Program (KIPP) middle schools through a 5th or 6th grade admissions lottery in 2008 or 2009. Those students are now old enough to have attended college for at least two years. This…

Educators, researchers, and policy makers concerned about college under-enrollment among underserved groups of students have traditionally focused reform efforts at the high school level.

This article focuses on the reported experiences of three focal students who participated in a Spanish/English dual language program in their southern California school district throughout their elementary and middle school years. All three students identify as Mexican-origin and speak Spanish, English, and the Indigenous language of Zapoteco and…

The purpose of this research is to examine the English language proficiency trajectories of 2,201 fourth- through eighth-grade Latino English learner (EL) students who differed by current English language proficiency and were enrolled in a dual language program. Results showed that (1) students in the four English language proficiency groups…

The influence of parental beliefs and behaviors on children's math confidence and performance is well documented, but few studies examine these associations over time, or in large samples of Latino/a families. This study used longitudinal data from 247 (114 sons and 133 daughters) mother-child dyads to examine whether maternal math gender…

Existing research on self-management skills shows that measures of self-management predict student success. However, these conclusions are based on small samples or narrowly defined self-management measures. Using a rich longitudinal dataset of 221,840 fourth through seventh grade students, this paper describes self-management gaps across student…

This article reports on students' problem-solving approaches across three representations--number lines, coordinate planes, and function graphs--the axes of which conventional mathematics treats in terms of consistent geometric and numeric coordinations. I consider these representations to be a part of a "hierarchical representational…

Despite post-racial rhetoric, stereotypes remain salient for American youth. We surveyed 150 elementary and middle schoolers in Northern California and conducted case studies of 12 students. Findings showed that (a) students hold school-related stereotypes that get stronger in middle school, (b) African American and Latino students experience…
