The investigation of students' conceptions of knowledge of mathematics and the process of knowing mathematics is important to provide an understanding of the phenomena behind students' performance. However, there is a scarcity of empirical investigation of students' beliefs about mathematics knowledge in the Indonesian context. This study aims to…

Student-reported quality and coverage of school-based relationships and sex education (RSE) vary, with gender/sexual-minority and disadvantaged students reporting poorer provision. Experience of RSE among younger adolescents is under-explored. We examined student-reported RSE coverage and priorities and how coverage, and sexual-health knowledge…

Scholarship on the 'manufacturing of citizenship' has focused primarily on European and American nationalism. Scholars have noted the scarcity of research on identity construction among children in the Diaspora. This study explores the role of the altruistic principle and the Middle Way approach (a political strategy for the resolution of…

Despite the intuitive appeal of purpose as a subject of inquiry and its associations with positive life outcomes, empirical research on adolescent purpose is limited. This exploratory study examined several dimensions of purpose--classification, engagement, and commitment--based on essay and survey responses from a sample of 124 low-SES and…

This study examined the association between having been bullied at school during the past 6 months ("bullied status") and not meeting physical activity (PA) recommendations of 60 minutes of daily PA during the past week among 8th- and 11th-grade Texas adolescents. Multiple logistic regression analysis was conducted to examine this…

Home language (HL) effects on academic language literacy have been extensively discussed. However, previous research has mostly focused on Indo--European languages. This study extends the literature by using data (n = 17,600) collected in a diversified language area: Guangxi, China. We examined the effects of four HLs and four socioeconomic…

Data from 1,312 middle school students from nine states in the U.S. were gathered in spring 2015 during an NSF grant initiative featuring middle school environmental science curricular activities. Surveys related to STEM dispositions, career interest, climate change, creative tendencies and attitudes toward school were completed by participants,…

Federal legislation and policy increasingly seek to address minority overrepresentation in special education due to concerns that U.S. schools are misidentifying children as disabled based on their race or ethnicity. Yet whether and to what extent this is occurring is currently in dispute. We estimated racial disparities in disability…

Writing is a demanding, multidimensional process that is, cognitively and socially, highly complex. Success in writing is vital to success in education and in the workforce. Writing is increasingly used to demonstrate learning through schooling and has the potential to contribute toward understanding and learning in the content areas. The project…

Recent advances in positive youth development theory and research explicate complex associations between adaptive functioning and risk behavior, acknowledging that high levels of both co-occur in the lives of some adolescents. However, evidence on nuanced overlapping developmental trajectories of adaptive functioning and risk has been limited to 1…

Modern biology has become increasingly molecular in nature, requiring students to understand basic chemical concepts. Studies show, however, that many students fail to grasp ideas about atom rearrangement and conservation during chemical reactions or the application of these ideas to biological systems. To help provide students with a better…

The new science education reform documents call for integration of engineering into K-12 science classes. Engineering design and practices are new to most science teachers, meaning that implementing effective engineering instruction is likely to be challenging. This quasi-experimental study explored the influence of teacher-developed, engineering…

As part of the National Assessment of Educational Progress (NAEP) in reading, students are asked to demonstrate their understanding of words as used in literary and informational texts. This focus on students' understanding of word meaning highlights the importance of vocabulary in reading comprehension. This report provides an overview of…

Research on science achievement disparities by gender and race/ethnicity often neglects the beginning of the pipeline in the early grades. We address this limitation using nationally representative data following students from Grades 3 to 8. We find that the Black-White science test score gap (-1.07 SD in Grade 3) remains stable over these years,…

This study tests the predictive associations between externalizing behaviors and internalizing symptoms and examines the mediating roles of social competence, parent-child conflicts, and academic achievement. Using youth-, parent-, and teacher-reported longitudinal data on a sample of 523 boys and 460 girls from late childhood to early…
