The heterogeneity in the developmental trajectories of math motivational beliefs (i.e., expectancies for success and subjective task value beliefs) was examined among Asian and Latinx male and female students from Southern California across Grades 8 through 10 (n = 2,710; 50% female; 85% Latinx; 15% Asian; M[subscript age] = 13.77). By conducting…

Secondary course assignment substantially determines a teacher's day-to-day work life, incentivizing them to realize their personal desires, which prior work shows tend to be working with more advanced students. Teachers have varying abilities to enact these desires, potentially due to their political capital, which is largely influenced by…

As immigrants account for an increasing proportion of American youth, understanding how these young people experience change in their citizenship status is an important, yet rarely examined area for research. There is a plethora of evidence that opportunities to participate in American society are stratified according to class, race and ethnicity.…

Few studies holistically examine how students experience the multiple dimensions of school climate and resilience promoting characteristics, or how these two constructs may be interrelated. This study utilised a sample of 78,550 7th, 9th, and 11th grade students in California. Roughly half of the participants were female (52%), and roughly half…

Background: The experiences of youth with intersecting LGBTQ+ and Asian American (AA) identities have been largely unexplored. This study explored these experiences of LGBTQ+ AA California youth with mental health, school climate, and school victimization. Methods: Drawing from the 2016-2017 California Healthy Kids Survey (N = 326,124), this study…

This study examined relations between student engagement and drug use using data obtained from the statewide biennial California Healthy Kids Survey. Latent variable modeling with confirmatory factor analysis indicated four conceptually distinct and psychometrically sound factors capturing academic motivation, school connectedness, caring…

This paper examines the extent to which transgender students' experiences with school-based victimization and school protective factors contribute to or reduce substance use. We conducted secondary analyses of school-based victimization, school protective factors, and substance use of a subsample of transgender students from the 2013-2015…

The purpose of this study was to explore grade-level differences (7th, 8th, and 9th) among junior high school students' perceptions of the effects of participation in physical education (PE) class on individual environmental stress. The role of physical activity as a stress reduction tool has been well documented. However, physical activity as a…

This study examined the association between participation in a school-based group-mentoring program (Project Arrive) and academic outcomes in a group of ninth-grade students who had been identified as at high risk of high-school dropout (n = 239). Comparison participants were ninth-grade students with similar levels of risk (n = 980). Using…

Little is known about the naturalistic development of mindfulness in adolescence and how it relates to changes in emotional well-being. The current longitudinal study examined the development of one dimension of mindfulness, nonreactivity to difficult inner experience (or in more colloquial terms, being able to notice, but "take a step…

Across countries, the age and timing of when children navigate school transition varies, as does provision of support during this challenging time. These two factors can heavily shape young people's adjustment, yet to date there is minimal research which has investigated how this period is navigated in different cultures. The aim of the present…

This study estimates the causal impact of 8th grade English learner (EL) reclassification on high school English language arts (ELA) standardized test scores, SAT (Scholastic Aptitude Test) reading, and on-track to graduate status. I apply a regression discontinuity design to rich administrative data from a large district in California. The…

Although there is substantial research that has guided middle school reform, there is insufficient support of Latinx students during their normative secondary transition (middle school to high school). Current research emphasizes that students who are not prepared when entering high school will face grim academic futures. The study explores the…

This dissertation explored the roles schools can play in the successful outcomes of large carnivore or keystone reintroduction projects. Schools are more than centers for knowledge acquisition--they connect their community and disseminate information quickly to a wide audience. This study took place in California's Eastern Sierra Nevada, a…

To date, there is a paucity of empirical evidence that examines gang membership in schools. Using statewide data of 7th-, 9th-, and 11th-grade students from California, this study focuses on the prevalence of gang membership by county, region, ethnicity, and grade level. Bivariate and multivariate logistic regression analyses were employed with…
