This study explored sexual orientation and gender identity as predictors of health literacy among adolescents attending New York City (NYC) public high schools. Many studies have demonstrated disparities in sexual health among sexual and gender minority (SGM) adolescents. However, little is known about their health literacy. Health literacy,…

This study shows that residual variation can cause problems related to scaling in exponential random graph models (ERGM). Residual variation is likely to exist when there are unmeasured variables in a model--even those uncorrelated with other predictors--or when the logistic form of the model is inappropriate. As a consequence, coefficients cannot…

This study explores how extracurricular activities experiences affect students' leadership development outcomes. The current status of students' experiences of extracurricular activities and leadership development outcomes identified. Also, it analyzed the correlation, as well as how they contribute to the college students' leadership. Lastly, the…

As human-induced climate change rapidly increases, information about climate change permeates each aspect of society. This study examines how learning sources pertaining to climate change influence self-reported pro-climate behaviour in adolescents. Cross-tabulation method, combined with correspondence analysis, has been conducted on data obtained…

This dissertation explored whether unnecessary linguistic complexity (LC) in mathematics and biology assessment items changes the direction and significance of differential item functioning (DIF) between subgroups emergent bilinguals (EBs) and English proficient students (EPs). Due to inconsistencies in measuring LC in items, Study One adapted a…

Mathematical giftedness (MG) is an intriguing phenomenon, the nature of which has yet to be sufficiently explored. This study goes a step further in understanding how MG is related to expertise in mathematics (EM) and general giftedness (G). Cognitive testing was conducted among 197 high school students with different levels of G and of EM. Based…

The aim of this study was to examine the relationship between the sport-confidence and the coach-athlete relationship in Turkish national male student-wrestlers, and to investigate whether educational status, wrestling style, wrestling category, and career of wrestlers were significant variables on student-wrestlers' sport confidence and their…

Employment status in high school has been shown to have a negative relationship with measures of academic achievement which some researchers have attributed to student characteristics such as demographics and socioeconomic status. The current study investigated differences in the demographic and socioeconomic characteristics of "working…

The purpose of this study was to examine whether variations in student achievement in college courses exist between high school students who took the courses as dual enrollment (DE) courses and academically comparable high school students (AIMS scholars) who took the courses upon matriculation to college. Additionally, the researcher explored…

This study examined rural-nonrural differences in postsecondary educational expectations and the attainment of expectations for grade 10 students attending rural and nonrural high schools in the Regional Educational Laboratory (REL) Midwest region and how these differences compare with rural-nonrural differences in the rest of the nation. For…

The purpose of this study was to examine postsecondary admissions outcomes for music and arts students as compared to their non-arts peers using nationally representative data (N = 14,900) from the Education Longitudinal Study of 2002. Controlling for certain observable differences between students who do and do not elect arts courses, music…

The role of mastery and performance goals in self-regulated learning (SRL) has received much attention. However, in collectivist and Confucian-heritage contexts, social-academic goals may also play an important, yet unexamined role in SRL. This study examined the association between social-academic goals and SRL. We tested a hierarchical model…

Students with disabilities are disproportionately involved within the bullying dynamic. Few studies have investigated the bullying involvement of youth with disabilities over time. The current study evaluated the victimization and perpetration rates of 6,531 students in Grades 3 through 12, including 16% with disabilities, over the course of 3…

Students who drop out of high school are at increased risk of a range of negative social and economic consequences, including lower earnings and poorer health. To reduce dropout rates and lessen these negative consequences, districts around the country are using early warning indicators to identify and provide supports for students at risk of…

The current focus on assessing "college and career readiness" raises an empirical question: How do high school tests compare with college admissions tests in predicting performance in college? We explored this using data from the City University of New York and public colleges in Kentucky. These two systems differ in the choice of…
