Noncognitive constructs such as self-efficacy, social awareness, and academic engagement are widely acknowledged as critical components of human capital, but systematic data collection on such skills in school systems is complicated by conceptual ambiguities, measurement challenges and resource constraints. This study addresses this issue by…

This study investigated the relative importance of three subdomains of early number competence (number, number relations, and number operations) in predicting later mathematics achievement in cross-sequential samples of pre-K, kindergarten (K), and first graders (N=150 at each grade). OLS-regression analyses showed that each subdomain predicted…

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 study assessed the prevalence of weapon-related behaviors and experiences in secondary schools in California, their intercorrelations, and predictors at the individual and school levels. This study is based on a representative sample of 889,726 secondary school students in California based on the California Healthy Kids Survey. Prevalence…

The world currently has more than three billion smartphone users. The smartphone is fully integrated into the daily life of individuals, including 95% of American teenagers. Excessive use of the smartphone leads to smartphone addiction and problematic smartphone use (PSU) which has been associated with depression, stress, reduced self-esteem, and…

In the spring of 2018 the Northern California/Nevada Section of the American Association of Physics Teachers was alerted to a local high school's plans to eliminate physics for the following school year. As part of the campaign to support the school's efforts to sustain physics in the following year, the physics offerings from the surrounding…

Strong evidence indicates that student expectations of success in mathematics decline in middle school. The goal of the present study was to examine whether the expectations of teachers and the quality of the student-teacher relationship play a role in these declines. A total of 201 (86 boys, 115 girls) Latino/a students (M = 11.0 years) and their…

Hispanic first-generation college students (FGCS) experience more potential barriers to college success than continuing generation college students (CGCS). With an eye toward identifying ways to support students in negotiating these barriers, there were three purposes to this study. First was to understand the variability among Hispanic FGCS based…

The primary purpose of this study was to explore the relationship between school climate and academic achievement in the Common Core State Standards era. This quantitative study involved 79 high school-level school districts from five counties in the southern California area. The essential research questions used to guide the study were designed…

Previous work has looked at the relationship between high school preparation and student performance in calculus-based introductory mechanics (physics 1) courses. Here, we extend that work to look at performance in introductory calculus-based electricity and magnetism (physics 2), and we look at the significance of what college math courses have…

African American male students face a multitude of challenges that may lead to poor academic and social outcomes at school. There is extensive research on the predictors of their problems, but far less on the factors that can lead to positive outcomes. To address this gap, this exploratory study asked two main questions. Does racial-ethnic…

Teacher retention has been studied for decades, yet it has recently assumed renewed significance due to current teacher shortages. This study was designed to determine whether teachers' job embeddedness (JE) is related to turnover. JE is found in organizational literature (Mitchell, Holtom, Lee, Sablynski, & Erez, 2001) and has been a robust…

The purpose of this study was to explore relationships between financial aid awards and measures of student academic achievement. Financial aid and academic records for 11,956 students attending an urban California community college were examined and analyzed using simultaneous linear regression and two-way factorial ANOVAs. Findings revealed a…

Additional to the lack of gender and ethnic diversity, the attrition rate among Physics and Engineering undergraduates is as high as 40%. Considering the impact of STEM gateway course on students' choice of major, we investigated the association between students' Expectancy-Value beliefs at the beginning of the class with their intent to persist…

Purpose: Sequential bilingual children in the United States often speak 2 languages that have different social statuses (minority-majority) and separate contexts for learning (home-school). Thus, distinct factors may support the development of each language. This study examined which child internal and external factors were related to vocabulary…
