Convergence And Divergence Of Opinion About Treatment Of Binocular Vision Disorders Among Vision Care Professionals, Sonia Young

Dissertations

There are three distinct professions prominent in the field of pediatric vision care. They are ophthalmology, optometry and orthoptics. All professions are integral to the detection and treatment of pediatric binocular vision disorders. However, distinct schools of thought exist to describe the best approach to pediatric binocular vision disorders and their treatments. Literature often highlights two opposing schools of thought represented by the “medical” and “behavioral” approaches. While there is academic debate about the merits and pitfalls of either approach, there is a paucity of nuanced perspectives which more closely resemble the ways in which pediatric ocular clinicians approach diagnosis …

“The Thorns Of The Most Severe Virtue”: Education, Religion, And Cultural Power In Michigan, 1798–1855, Kyle Christopher Vanderwall

Dissertations

This project seeks to demonstrate the centrality of education and religion as cultural power levers used by Americans, Odawa, and Catholic missionaries. Though the power of each culture was uneven, efforts to create educational institutions imbued with different denominations of Christianity, as well as continued contestation over land, remade the cultures of all involved. Americans privileged state-building practices, the Odawa acculturated to remain in Michigan when removal policies were enacted throughout the United States, and the Catholic church attempted to proselytize Indigenous communities.

Although the ethnohistorical method needed to be understood in order to write this project, it is not …

The Effects Of Fluency Building On Undergraduate Student Performance, Lauren B. Shibley

Dissertations

The conceptual framework for this study incorporates Strayhorn’s (2019) college students’ sense of belonging theoretical model as a foundation with Museus’s (2014) culturally engaging campus environment model as a lens for analysis of the findings.

Using a hermeneutical phenomenological approach, 12 Black undergraduate students were recruited to participate. Each of the students attended a public 4-year PWI in the Great …

Making Sense Of The Faith-Based School’S Mission: An Instrumental Case Study Exploring How The School’S Espoused Mission Is Enacted, Richard Mingerink

Dissertations

What happens in the space between a school’s espoused mission and the enactment of that mission in the classroom? For faith-based schools—institutions whose very identity rests upon a religiously grounded purpose—this question is not merely technical but existential. While these schools publicly espouse missions centered on a religious faith, research consistently suggests that what is proclaimed on paper is not always what is practiced in classrooms. The persistent gap between espoused mission and enacted practice raises a critical question: how do educators actually make sense of their school’s religious mission, and how does that sensemaking shape what they do?

This …

Generations At Work: Examining Differences In The Nonprofit Sector, Cory J. Bergeron

Dissertations

This non-experimental quantitative dissertation examined generational differences among non-management employees in the United States nonprofit sector, where multiple generational cohorts work side by side. The problem addressed is that nonprofit leaders’ limited understanding of how distinct generational experiences shape employees’ work-related attitudes and preferences can contribute to conflict, reduced engagement, and costly turnover in already resource-constrained organizations. Grounded in Mannheim’s generational theory and Becker’s human capital theory, the study conceptualized generational cohorts as groups whose shared formative experiences influence what they value in their work context and how those values translate into human capital that affects organizational outcomes.

Exploring The Lived Experiences Of Second-Career Educators, Kyle Avink

Dissertations

School districts across the United States face a persistent teacher shortage driven by high attrition rates, declining enrollment in teacher preparation programs, and increasing demands on educators (Carver-Thomas & Darling-Hammond, 2017). Teacher attrition is especially high within the first three to five years, with nearly 40-50% of new teachers exiting within their first five years (Carver-Thomas & Darling-Hammond, 2017; Cells et al., 2023; Gray et al., 2015; Ingersoll et al., 2025). In response, many states have expanded alternative certification pathways that allow professionals from other fields to enter teaching, making second-career educators a potential solution to workforce challenges (Afacan, 2022; …

Unpacking American Reception Of Glocalized Non-English Content In The Netflix Era, Sur Govindarajan

Dissertations

The swift growth of streaming services has revolutionized the worldwide distribution of media, making it possible for non-English and non-English-adjacent content to reach American consumers on a never-before-seen scale, which is sometimes perceived as an indication of increasing cultural tolerance. However, while a lot is known about what audiences see, far less is known about how they really understand and assess these stories. There is a fundamental vacuum in our understanding of audience reception as a lived, meaning-making process because previous research has mostly focused on consumption patterns. In order to close that gap, this study examines how American audiences …

Host Families’ Perspectives Of The Impact Of The Commodification Of Education On The Student-Host Family Relationship In Study Abroad, Guadalupe Bustamante

Dissertations

The growing commodification of education has reshaped study abroad in ways that extend beyond marketing and program design. While homestays have traditionally been viewed as the ideal format for cultural immersion and language acquisition, research has largely overlooked how these trends affect the student-host family relationship from the family's perspective.

This study examines whether, and, if so, how Spanish host families perceive their roles and relationships with the American students they host have been impacted by these trends. Using a qualitative exploratory case study design, the research focused on representatives from eight families in Madrid, who have hosted U.S. students …

Agents Of Agency: Identifying Teacher Traits And Trainings Associated With Promoting Student Agency, Clara Mateo

Dissertations

This study shifts the focus of mathematics teacher quality from the traditional metric of test scores to “student agency,” defined as a learner's capacity to access power, make decisions, and take ownership of their learning process. While the literature on student agency provides ample qualitative insights, it is largely composed of small-scale studies. This research addresses this gap by conducting a large-scale, nationwide quantitative analysis to identify teacher factors associated with the promotion of student agency. The central research question is: What teacher demographics, dispositions, and professional development experiences are associated with increased student agency?

This study used a cross-sectional …

The Impact Of Framing Effects And Moral Values On Prosocial Engagement, Olajuwon Olagbegi

Dissertations

Framing effects can shape perceptions, beliefs and behavior, particularly in prosocial contexts. The current study examined how language framing (social justice, social activism, volunteerism) and moral values influence interest in prosocial engagement across low- and high-cost helping scenarios. Participants (N = 219) were randomly assigned to one of three framing conditions and reported willingness to help in both low- and high-cost situations. They also completed the Moral Foundations Questionnaire. Replicating prior work (Olagbegi and colleagues, 2024), participants were more willing to engage in low- than high-cost helping. Across conditions, social justice framing elicited the greatest willingness to help. Higher fairness …

Lyapunov-Krasovskii Based Approach To Time-Delay Systems: Computational Efficiency And Feedback Control, Huan Phan

Dissertations

Time-delay systems arise naturally in many engineering applications due to sensing,actuation, communication, and computation delays. The presence of delays has a significant influence on system performance both positively and negatively. Although Lyapunov--Krasovskii functional (LKF) methods provide a systematic framework for stability analysis and controller synthesis, their implementation often suffers from high computational complexity, particularly for large-scale systems and systems involving multiple feedback channels. This dissertation addresses both computational efficiency and feedback control for linear time-delay systems.The first part of this dissertation develops a decomposition-based approach to reduce the computationalburden of stability analysis. By exploiting structured invariant subspaces associated with the …

A Phenomenological Study Of Teachers Who Use Oral Reading To Foster Student Reading Fluency And Engagement, Donyetta Grimes

Dissertations

The National Reading Panel (2000) recommends oral reading instruction as a means to improve overall reading fluency and reading comprehension. Oral reading fluency is a necessary foundational skill, and students who have not mastered it by the end of third grade, when students transition from learning to read to reading to learn, become struggling adolescent readers (Ming, 2018). Furthermore, there is a lack of research on reading fluency past the primary grades (Makebo et al., 2022). Additionally, research gaps exist when considering teachers’ actual practices during reading instruction (O’Sullivan et al., 2009). This gap is particularly concerning considering that teachers …

Restorying The Reader: Adolescent Narratives Of Identity, Context, And Motivation, Jennifer R. Gardner

Dissertations

This present study examined how adolescents narrate their reading experiences and what those narratives reveal about reading identity, motivation, and engagement. This study responds to a persistent problem in literacy education: adolescent reading is often framed through disengagement or reduced to isolated constructs, while students’ lived reading experiences across school, home, digital, linguistic, and social contexts remain underexamined. Guided by Self-Determination Theory, Intersectionality, and Reader Response Theory, this study centers on adolescent voices and treats these participants’ stories as the primary avenue of understanding how they experience and interpret their reading lives and selves.
