A Design Based, Mixed Method Study On Evaluating Traditional Grading Practices And The Implications For Mastery Learning And Educational Equity In A Midwestern School District, Christina Kirchner

Dissertations

“Grades are an essential currency of our schools. Schools, colleges and employers use grades to determine many important, and in some cases, life-altering decisions-college admission, financial aid and scholarships, athletic eligibility, promotion, retention, awards, and supports” (Feldman, 2018, p. 3). Grading is not addressed in teacher preparation programs, or within professional development during teachers’ careers; teachers have chosen their own way to grade guided by their own personal experiences, uninformed of research or best practice. Using a human centric, design-based approach, the researcher identified multiple discrepancies with grading practices among the K-12 school organization. Within the discrepancies, other issues were …

The Correlation Between Depression And Gendered Racism Among Black Women, Charmagne M. King

Dissertations

Black women face unique challenges related to intersecting racial and gender-based discrimination, often referred to as gendered racism. Previous research has indicated this form of oppression may significantly affect mental health, particularly depression. However, few studies have examined how gendered racism interacts with racial identity and demographic factors (e.g., age, marital status, geographical location) to predict depressive symptoms. Using a sample of 164 self-identified Black women, this study investigated the correlational relationship between gendered racism and depression among Black women and examined how gendered racism, racial identity, and key covariates (age, marital status, and geographical location) predict depressive symptomatology. The …

Understanding The Afghan Newcomer Experience From The Perspectives Of Teachers And Students, Elisabeth C. Trost

Dissertations

Newcomer English learners (ELs) often arrive in the United States having fled persecution, economic or political oppression, war, or natural disasters in their country of origin. They are new to the English language, new to the American school system, at times well into their educational journey, and sometimes have missed out on significant amounts of formal schooling. Many also carry trauma from the circumstances that forced them to leave their homes. Most schools are not fully equipped to welcome these students and their families into the learning community, nor are they prepared to address the unique challenges newcomer ELs face. …

A Phenomenological Qualitative Study Of Sense Of Community In An Inner-City Parochial School: Expanding The Seats At The Table., Mary Andree Darnall

Land Access As Liberation: A Qualitative Study On Faith, Food, And Farming Of Urban And Rural Black Land Stewards In The United States, Dominique Edwards

Dissertations

Since 1920, Black farmers in the United States have held less than 2% of the nation's farmland, a direct result of race-based discriminatory policies embedded within federal, state, local, and county-level institutions (Daniel, 2013). Structural barriers—ranging from exclusionary lending practices by the U.S. Department of Agriculture (USDA) to the systematic dispossession of land through legal loopholes, heirs’ property laws, and violent racial terror—have contributed to this staggering decline in Black land ownership (Gilbert et al., 2002). The erosion of Black agrarian landholdings intensified in the latter half of the 20th century, as government programs, civil rights legislation, and technological advancements, …

Research from the United States Department of Veterans Affairs (USDVA) underscores the prevalence of these issues, indicating that approximately 1 in 10 veterans from the Iraq or Afghanistan wars treated by the VA are diagnosed with a SUD (Veterans Affairs, 2023). Additionally, veterans from all eras show a higher propensity for binge drinking when compared to the general population, further …

The Rose That Grew From Concrete: Exploring The Romantic Experiences Of Black Men With Histories Of Childhood Sexual Abuse, Tatyana Nichelle Smith

Dissertations

Contemporary research typically characterizes Black heterosexual relationships by dismal marriage and divorce rates, largely ignoring the reality of how Black men develop attachments with their romantic partners and therefore continuing to perpetuate deficit perspectives of Black men (e.g., the cause of conflictual romantic relationships and “broken” Black families). What may be less understood about these relationships is the influence of childhood trauma, such as childhood sexual abuse, and Black men’s experiences of gender role conflict. Research shows that Black men’s experiences of childhood sexual abuse and socialization about masculinity have important implications for how they come to view themselves and …

Their engagement was not primarily with educational materials …

Probing Shielding Tensor Components Of Amino Acids Using Nuclear Magnetic Resonance, Shiva Agarwal

Dissertations

Chirality is fundamental to terrestrial life. While most amino acids exist as nonsuperimposable mirror images, amino acids in terrestrial life are homochiral, with the L-enantiomer being ubiquitous. The detection of an excess of L-amino acids in carbonaceous meteorites suggests that extraterrestrial processes may have contributed to this enantiomeric excess (ee). One proposed mechanism, the magnetochiral model, provides a potential explanation for this phenomenon in stellar environments characterized by strong magnetic and electric fields and the presence of relativistic leptons. According to this model, subtle differences in the electronic environments of chiral amino acids under such conditions …

The profession has a rich history of developing and perpetuating oppressive systems that have ignored …

The Impact Of Restorative Practices Intervention On School Culture, Lisa Peloquin

Dissertations

The American educational system, historically designed to empower a few while training the majority to be docile workers, is increasingly being called upon to promote greater equity. While some reform efforts promote highly restrictive behavioral policies to boost student achievement, these approaches often serve to recreate the oppressive school systems they seek to reform. Restorative practices, an alternative approach to school reform, emphasizes creating a culture of strong relationships, where children learn the academic and social emotional skills they need to be successful. This paper presents a case study of one urban, public school’s implementation of restorative practices, examining its …

Intersecting Inequities: Latinx Access To Mental Health Services, Melissa Thorson

Dissertations

This study examined barriers to mental health service utilization among Latinx populations using data from the 2022 National Survey on Drug Use and Health (NSDUH). Through the theoretical frameworks of Minority Stress Theory and Toxic Stress Theory, the study investigated the relationships between age, language proficiency, socioeconomic status, and mental health service access among different Latinx subgroups. Statistical analyses included chi-square tests, multiple regression, and mediation analyses on a sample of Latinx adults (N = 9,852). Results indicated associations between age and English proficiency (χ² = 145.23, p < .001, Cramer's V = 0.38), with 45% of adults aged 50 and older reporting limited English proficiency. Socioeconomic analysis revealed that 32% of older Latinx adults reported family incomes below $20,000, with insurance status partially mediating the relationship between income and service utilization (indirect effect = 0.15, 95% CI [0.08, 0.23]). differences in utilization rates emerged among Latinx subgroups (F(6, 1243) = 8.76, p < .001, η² = 0.12), with Mexican-origin individuals showing higher utilization (10%) compared to Puerto Rican individuals (2-3%). Age and socioeconomic status demonstrated interaction effects (β = 0.18, p < .01), while language proficiency moderated the relationship between age and service utilization (β = 0.24, p < .001). These findings suggest that barriers to mental health service utilization among Latinx populations are complex and interconnected, requiring multilevel interventions that address linguistic, cultural, and socioeconomic factors simultaneously. Implications for healthcare policy and service delivery are discussed, emphasizing the need for culturally responsive and linguistically appropriate mental health services.
