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.…

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…

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…

Metadata that are often captured and discarded when students take achievement tests on a computer can transform processes for identifying, monitoring, and supporting students who might benefit from social-emotional learning (SEL) interventions. This submission presents a metric called response-time effort (RTE) that relies on such metadata. 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…

Although graduation rates are rising, the high school dropout problem remains a national crisis, and evidence-based information about interventions for at-risk students is critically needed. Prior research shows that Check & Connect, an individualized mentoring program, has positive effects on school persistence and progression for students…

School belonging (i.e., social connectedness to school) has positive implications for academic achievement and well-being. However, few studies have examined the developmental antecedents of school belonging, particularly for students of Mexican origin. To address this gap in the research literature, the present study examined reciprocal relations…

The "Pathway to Academic Success Project" trains teachers to improve the reading and writing abilities of English learners (ELs) who have an intermediate level of English proficiency by incorporating cognitive strategies into reading and writing instruction. This What Works Clearinghouse (WWC) intervention report, part of the WWC's…
