Disparities in Mathematics performance have been shown across race and gender for decades, although little research has reported the race by gender nexus in terms of disparity. In turn, research done to ameliorate these disparities have assumed that these differences are primarily among student populations who need remedial learning improvement.…

Using panel data from three successive collective bargaining (CBA) negotiation cycles from 277 California school districts in a difference-in-differences framework, I investigate the relationship between changes in CBA restrictiveness and racial and economic achievement gaps over time. I find that achievement gaps in California are smaller where…

Curriculum-based measurements (CBM) are used in schools to screen students for academic difficulties. Oral reading fluency curriculum-based measures (CBM-R) are the most popular, yet several studies have identified predictive bias in CBM-Rs in relation to key variables (e.g., race, sex). Despite a massive increase in the use of these measures as…

Objective: Community colleges have considerable potential to grow the number of individuals who complete STEM baccalaureate degrees and to broaden access to educational opportunities in STEM. However, efforts to tap this potential have been hampered by nagging questions about whether community colleges prepare students adequately for advanced STEM…

Undergraduate student participation in out-of-class activities yields a range of documented benefits and represents an area of study that can inform efforts to increase persistence in science, technology, engineering or mathematics (STEM) majors, particularly for underrepresented groups. This study was designed to explore the impact of selected…

Purpose: This study examined how participation in the Service Platoon program of The Mission Continues (TMC) impacts self-reported purpose in life (PIL), interpersonal support (IS), and civic engagement (CE) among military veterans.

This dissertation is comprised of three essays, each examining a different topic in labor economics. In Chapter 1, I examine the productivity and selection effects of K-12 teacher tenure by leveraging variation from New Jersey's TEACHNJ Act. This law extended the pre-tenure period from three to four years and allowed districts to dismiss…

Recent estimates show nearly 90% of school districts nationwide offer some form of online credit recovery. Despite its widespread adoption, there is a dearth of research surrounding the suitability of online credit recovery for students. This study examined potential success factors of students enrolled in virtual recovery courses in a school…

Background: The importance of high school completion for jobs and postsecondary opportunities is well- documented. Combined with federal laws where high school graduation rate is a core performance indicator, school systems and states face pressure to actively monitor and assess high school completion. This proposal employs machine learning…

Six-year college graduation rates for Hispanic and White students from 17 cohorts were analyzed using data from the U.S. Department of Education's IPED System. Results from regression analyses confirmed statistically significant positive linear trends for Hispanic and White students and statistically significant differences between the two…

Cyber bullying has become more pervasive as a result of advances in communication technology such as email, text messaging, chat rooms, and social media sites. Despite the growth in research on correlates associated with engagement in cyber bullying, few studies test the applicability of criminological theories to explain engagement in cyber…

School violence, school violent victimization, and suicidal ideation among adolescents are serious public health concerns. This pilot study investigated the influence of steroid use on problem behaviors. Secondary data analyses of the 2014 PRIDE Questionnaire were performed based on information collected from 38,414 high school adolescents.…

Background: Because marijuana is becoming more accessible and perceived norms of use are becoming increasingly more favorable, research is needed to understand characteristics of marijuana acquisition among adolescents. Purpose: The study purpose was to examine whether sources and locations where adolescent users obtain and use marijuana differed…

The present study used nationally representative data from the U.S. Panel Study of Income Dynamics (PSID) merged with census-track data from the American Community Survey (ACS) to model race-ethnic disparities in overweight, obesity, and obesity-related disease among children and adolescents as a function of neighborhood race-ethnic segregation,…

Adolescent boredom is associated with maladaptation and negative developmental outcomes, yet little is known about the prevalence and correlates of high boredom. Drawing from a broad psychosocial framework, the present study examined rates of high boredom and sociodemographic and contextual correlates among nationally representative samples of 8th…
