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…

For many years, research has supported the value of using real-life experiences as teaching opportunities (Noobanjong & Louhapensang, 2017; Powell, 2015). This is just as true of teaching writing as of anything else. In fact, when learners use writing (such as journaling) to share their experiences, they benefit in several ways, including…

Students with autism spectrum disorder (ASD) often exhibit challenges with reading development. Evidence-based interventions and specialized approaches to reading instruction are currently being implemented across educational contexts for learners with ASD (Machalicek et al., 2008), yet there is limited understanding of how core ASD features may…

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…

This study examined associations among a concurrent set of social-emotional strengths and school membership across the United States (N = 1,009) and Chinese (N = 747) students aged 9 to 11 years old. Results identified significant positive relations of school membership with four social-emotional strengths (i.e., gratitude, optimism, zest, and…

Early adolescence is a critical time for examining academic motivation, specifically motivation to read. To support self-determined motivation to read, students' needs for competence, autonomy, and relatedness must be met within the classroom context. Because classroom instructional practices are a key component of adolescents' daily experiences…

We investigated the relationship of self-sexualization to self-objectification, weight concerns, self-efficacy, academic outcomes, and career aspirations among preadolescent girls. Participants were 89 six- to nine-year-old girls; parental reports were also obtained. Two thirds of girls showed signs of self-sexualization by choosing a sexualized…

The current study identified alcohol and cannabis use trajectories among a sample of Mexican-origin youth and examined cultural and familial correlates from childhood to adolescence. Mexican-origin youth (N = 674) from Northern California were assessed annually from ages 10 to 17 (8 waves). Latent class growth modeling examined variability in…

The purpose of this study was to examine time-varying associations of parent-adolescent cultural conflict with depressive symptoms and grade point average (GPA) among Chinese Americans from ages 11-22. We pooled two independently collected longitudinal data sets (N = 760 at Wave 1) and used time-varying effect modeling (TVEM) to show that the…

Detroit's Flip the Script afterschool program offers academic support, leadership development, and guidance from positive male mentors to young men of color ages 11-15. At Male Leadership Academy, another program in the city's West Side, youth receive similar services, including life lessons from peers and adults provided in a guest speaker…

Online physical education (OLPE) has been viewed as an oxymoron. Physical education curriculum at all levels seeks to help learners grow socially in the way they interact and deal with diverse and challenging fellow students and settings. Students who have no contact with other students while they are at home for various reasons may not be able to…

The aim of this study was to assess whether and how a sustained instructional focus on argumentation might improve children's understanding and application of key epistemic criteria for scientific arguments. These criteria include the articulation of clear, coherent causal claims, and the explicit justification of such claims with appropriate…

Self-determination theory and substantial research findings suggest that more desirable outcomes may occur when participants are able to choose their prevention or treatment interventions, as having a choice may lead to greater motivation and feelings of self-efficacy. The present study examined the influence of having a choice of family-based…

Nationally, both science and agricultural education professional organizations have identified agriculture as a fundamental technology to be studied by students, with the goal of achieving an understanding of the agri-food system necessary for democratic participation. Benchmarks representing the content that K-12 children need to understand about…

The theory of evolution by natural selection has revolutionized the biological sciences yet remains confusing and controversial to the public at large. This study explored how a particular segment of the public--visitors to a natural history museum--reason about evolution in the context of an interactive cladogram, or evolutionary tree. The…
