The main purpose of this study was to compare delay discounting of hypothetical monetary outcomes by adolescents adjudicated of illegal behavior to that of college students in order to lay a foundation for future discounting work with adjudicated adolescents. It is important to note that we conducted this work during the COVID-19 pandemic, which…

This dissertation examines two key axes of inequality in higher education -- gender and socioeconomic status (SES) -- in terms of differences in college persistence and college major using the nationally-representative High School Longitudinal Study of 2009. While gender differences in terms of STEM majors has been oft-studied, this dissertation…

Dual language education is an innovative educational model available for families selecting schools through school choice. While extensive research supports the academic benefits of dual language programs (DLPs) for non-English native speakers and communities of color in the United States, enrollment often does not reflect these populations. This…

The Conover Solution is a nonparametric method used to analyze relative growth in students' achievement on state tests administered on two or more occasions. However, there has been very little research assessing the robustness of this method in the presence of missing data. Using vertically scaled and non-vertically scaled data from the math…

The divide between those who do and those who do not excel in mathematics is patterned in problematic ways. Women and people of color are typically underrepresented in Science, Technology, Engineering, and Math (STEM) and other quantitative fields (ex. Finance) where mathematics plays gatekeeper. However, mathematics is not a subject these groups…

TIMSS and PIRLS assess representative samples of students at regular intervals, measuring trends in student achievement and student contexts for learning. Because individual students are not tracked over time, analysis of international large-scale assessment data is usually conducted cross-sectionally. Gustafsson (2007) proposed examining the data…

Researchers are increasingly interested in the cognitive behaviors students display during tests. This interest has led researchers to look for innovative ways to collect this type of data. Due to the proliferation of computer-based assessments, process data has become popular for its ability to help show what students know, what students don't…

The purpose of this study was twofold. The first purpose was to analyze exit data collection systems in Mississippi school districts (including a content analysis of the instruments used to collect exit data) to determine how many districts collected data from exiting teachers. The second purpose was to examine teacher characteristics (race,…

This dissertation investigates several topics in state merit-based financial aid research. The main research content includes three separate studies, primarily using the administrative datasets from the Missouri Department of Higher Education. The first study is an empirical paper that examines the effects of the Missouri Bright Flight Scholarship…

Heart failure (HF) is a preventable and serious life threatening disease. Robust information is available on patient satisfaction when telehealth is used to manage chronic illness, but minimal information is available on Advance Practice Nurse (APN) satisfaction when APNs use this modality to deliver remote healthcare. The purpose of this project…

Purpose: The purpose of this journal-ready dissertation was to determine the degree to which differences were present in reading, mathematics, and both subjects college-readiness for English Language Learners who were enrolled in Texas high schools. In the first investigation, the extent to which English Language Learner boys differ in their…

Many telephone surveys require interviewers to observe and record respondents' gender based solely on respondents' voice. Researchers may rely on these observations to: (1) screen for study eligibility; (2) determine skip patterns; (3) foster interviewer tailoring strategies; (4) contribute to nonresponse assessment and adjustments; (5)…

The purpose of this study was to determine if significant relationships exist for any of the variables, age, gender, previous GPA, test scores (ACT, Compass), number of accumulated credits, and student success in Biology. This study strived to determine what academic/admissions data can be used to determine the likelihood of student success in…

This multiple methods (Denzin, 1978) study investigated two instructional approaches, traditional module and electronic Problem-Based Learning instruction (e-PBL), used within a middle school engineering classroom focused on the variables of engagement, content knowledge, student self-assessment and teacher assessment of problem solving solutions.…

Purpose: One purpose of this study was to determine the extent to which a difference was present in the STEM degree attainment of all students and particularly of URMs between the 2001 and the 2009 academic year. The second purpose of this study was to determine the extent to which a difference was present in the attainment of STEM associate…
