This dissertation investigates the impact of limited technology access, the quality of remote learning experiences, and racial disparities on SAT math scores among 11th-grade students. The study spans two academic years, 2018/2019 and 2022/2023, offering a longitudinal perspective on the trends in math scores. The research employs a quantitative…

The SAT has long been used to assess students' readiness for college and to create competitiveness in college admissions. However, it has become a topic of controversy as stakeholders and researchers question its necessity, value, and validity especially where it concerns equitable access to post-secondary opportunities for underrepresented…

An emerging area of research on the diversification of science, technology, engineering, and mathematics (STEM) is that of queer and trans (QT) students who are interested in STEM education and disciplines. The purpose of our study was to identify differences in high school mathematics educational experiences by sexual orientation and gender…

Biodiversity loss and rising global challenges are directly linked to the current climate crisis. Peoples' behaviors and lives are being negatively impacted daily, ushering in a new wave of physiological and emotional distress referred to as eco-anxiety, which is being experienced by young people. Urgent concerns for the need for environmental…

Despite recent calls to more fully incorporate multimodal perspectives into literacies research, there is still limited scholarship examining how students critically engage in reading activities by drawing on embodied practices. Racially and linguistically minoritized students are particularly disadvantaged by dominant logocentric and…

Lesbian, gay, bisexual, and queer (LGBQ) youth experience more heterosexist bullying victimization than their straight peers, which contributes to mental health disparities. However, LGBQ youth may simultaneously experience other types of bias-based bullying (e.g., racist, cis-sexist, and able-ist bullying). Informed by intersectionality theory,…

The COVID-19 pandemic affected education, causing schools in the United States to switch from face-to-face to remote learning modalities. The purpose of this study was to examine the impact of educational modalities on academic achievement in K-12 education to contribute to evidence-based decision-making in science education by practitioners and…

The racial/ethnic disparities and average declines in science, technology, engineering, and mathematics (STEM) motivation during adolescence are worrisome. Although STEM motivational beliefs are theorized to function in conjunction with one another, the unique patterns and how they change over time for different racial/ethnic groups remain…

Given math's importance, states are adopting a range of K12 policies to improve math outcomes. As these and other policies unfold, policymakers need to monitor intended outcomes and ultimately gauge impact. They need answers to basic questions: Are more students taking and passing algebra and advanced math? Are performance gaps changing between…

The problem addressed in this quantitative ex-post facto study was that African American, Latino, and Native American students have lower reading fluency than Caucasian counterparts. The purpose of this study was to determine to what extent incorporating more literature written by African American, Latino, and Native American authors had on the…

This study investigated the impact middle school tracking has on outcomes in high school and the factors associated with those outcomes. Utilizing data from a large, diverse school district, this quantitative study investigated the relationships between middle school and high school English course enrollment among 4,503 middle school students. The…

This study utilized quantitative research methods using the Montana Office of Public Instruction's Growth and Enhancement of Montana Students (GEMS) data set. This quantitative research is important because it provides insight on the following relationships (1) Is there a statistically significant difference among students from different races on…

Dual enrollment (DE) is one of the fastest growing programs that support the high school-to-college transition. Yet, there is limited empirical evidence about its impact on either students' college application choices or admission outcomes. Using a fuzzy regression discontinuity approach and data from two cohorts of ninth-grade students in one…

Objective: Sleep is vital for healthy development, yet most adolescents do not meet recommended nightly hours. Although racial/ethnic minorities often experience relatively worse sleep outcomes compared with White peers, little is known about how the sleep-mental health relationship holds across diverse groups or how family relationships affect…

Teachers of color increase school success for students of color. Yet, little attention has been paid to whether school attendance behaviors also increase from same race and ethnicity matches. To address this, our study used administrative data provided by a California high school district for the school years 2014 to 2018. We explored student…
