Navigating Predominantly White Institutions: A Narrative Inquiry Restorying Native American And Indigenous Students' Lived Experiences Of Higher Education, Chandra Anderson Sep 2026

Navigating Predominantly White Institutions: A Narrative Inquiry Restorying Native American And Indigenous Students' Lived Experiences Of Higher Education, Chandra Anderson

Doctor of Education Program Dissertations

Previous research has examined retention rates of Native American and Indigenous students within the United States in higher education; however, there remains a significant narrative silence regarding the lived stories and personal chronologies of these students (Brayboy et al., 2015; Davidson & Lopez, 2023; Oxendine et al., 2018). The purpose of this qualitative narrative inquiry was to elicit and restory the lived narratives of Native American and Indigenous students enrolled in predominantly White institutions (PWI) of higher education. This study’s literature review themes include: (a) history of Native American and Indigenous students, (b) contemporary research on Native American and Indigenous …

Teacher Mentoring As A National Imperative: A Multi-Paper Dissertation, Ramiro Pesina

Human Resource Development Theses and Dissertations

This multi-paper dissertation investigates teacher mentoring as a critical intervention in human resource development designed to address the complex challenges facing the teaching profession, including high attrition rates and the need for sustained professional support. The study is organized into three connected studies: an integrative literature review on technology enhanced mentoring, a longitudinal qualitative study that devises a comprehensive mentoring model covering cognitive, emotional, and behavioral aspects, and a phenomenological case study in which a formally structured mentoring program in a North Texas school district is analyzed in terms of execution and outcome. Critically important findings indicate that well-crafted mentoring …


A Fundamental Study Of Fatty Acid Ionic Liquids And Their Effects On Biomolecules, Achismita Dutta Sep 2026

A Fundamental Study Of Fatty Acid Ionic Liquids And Their Effects On Biomolecules, Achismita Dutta

Theses and Dissertations

Fatty acid ionic liquids (FAILs) are a class of ionic liquids (ILs) with relatively low toxicity and potential applications in biological systems. This study examined the interactions of tetramethylguanidinium decanoate, tetramethylguanidinium octanoate, choline decanoate, and choline octanoate with lipid membranes, proteins, and nucleic acids. Membrane leakage experiments using model lipid vesicles showed that decanoate-based FAILs produced greater membrane permeabilization than octanoate-based analogues, consistent with their higher membrane permeability. These effects were stronger for the ILs than for decanoate alone and occurred below the critical micelle concentration (CMC), suggesting that micelle formation may not be essential for membrane disruption. The ability …


A Hybrid Rule-Based And Large Language Model Framework For Extracting Acronym–Definition Pairs From Scientific Literature, Petro Skrypnyk Sep 2026

A Hybrid Rule-Based And Large Language Model Framework For Extracting Acronym–Definition Pairs From Scientific Literature, Petro Skrypnyk

Theses and Dissertations

Authors of scientific papers rely heavily on acronyms and often use them without defining them, making the literature harder to read and index. This thesis develops and evaluates a hybrid rule-based and large language model (LLM) framework that extracts acronym–definition pairs from scientific PDF documents. It extends an earlier Rowan University system that combined a regular-expression parser with a single LLM on 200 papers. That system showed that neither the parser nor the LLM alone is sufficient for accurate extraction of the pairs. The framework is a fully automated pipeline from PDF input to scored results. It compares four LLM …


Effects Of Social Comparison Instructions On Affect, Motivation For Healthy Behavior, And Health Behavior Selections: Guidance To Identify Or Contrast, Raj Harsora Sep 2026

Effects Of Social Comparison Instructions On Affect, Motivation For Healthy Behavior, And Health Behavior Selections: Guidance To Identify Or Contrast, Raj Harsora

Theses and Dissertations

Engaging in healthy behaviors early in life is crucial for preventing noncommunicable diseases such as type 2 diabetes, cancer, and heart disease. College is an optimal period to establish these habits, yet students often engage in poor dietary and physical activity practices; thus, identifying effective health behavior change techniques for this population is essential. Social comparisons are known to influence health behaviors, yet no research has tested comparison instructions as a behavior change technique, particularly identification versus contrast with upward and downward targets. Using a preregistered protocol (https://osf.io/z29en), we tested whether guiding college students (N=664) to identify with or contrast …


Problematic Technology Use And Quality Of Life In College Students With Varying Levels Of Schizotypy, Joseph P. Skinner Sep 2026

Problematic Technology Use And Quality Of Life In College Students With Varying Levels Of Schizotypy, Joseph P. Skinner

Theses and Dissertations

Problematic Technology Use (PTU) has emerged as a growing concern with technology’s continual integration into daily living. Individuals higher in schizotypy may be particularly vulnerable to the negative consequences of digital environments. The present study cross-sectionally examined associations among schizotypy, PTU, and quality of life (QOL) in 533 college students using structural equation modeling. Consistent with hypotheses, greater total schizotypy was associated with higher PTU and lower QOL. Additionally, positive, negative, and disorganized schizotypy all uniquely predicted poor QOL with the negative domain demonstrating the strongest standardized association. Contrary to hypotheses, PTU did not significantly moderate the relation between total …


Struggling Readers Collaborate On Reading Interventions For Fifteen Minutes A Day, Jordan Dobzanski Sep 2026

Struggling Readers Collaborate On Reading Interventions For Fifteen Minutes A Day, Jordan Dobzanski

Theses and Dissertations

This thesis examines what happens when struggling readers collaborate on reading intervention practices for fifteen minutes a day. Relevant theories that guided this research included Bandura’s Social Learning Theory, Vygotsky’s Social Constructivist Theory, and Lankshear and Knobel’s New Literacies Theory. Throughout the six-week study, four third-grade students identified as below grade level participated in a collaborative reading intervention that focused on vocabulary development, fiction and informational text comprehension, student-led discussions, digital literacy activities, and reflective journaling. Students worked together in structured literature circles while engaging in literacy activities connected to their classroom curriculum. Data were analyzed through triangulation in order …


Polymer Nanocomposite Dielectrics For High-Temperature Superconducting Cables: Cryogenic Characterization And Testing Environment Development, Jared R. Ericksen Sep 2026

Polymer Nanocomposite Dielectrics For High-Temperature Superconducting Cables: Cryogenic Characterization And Testing Environment Development, Jared R. Ericksen

Theses and Dissertations

High-temperature superconducting (HTS) cables require dielectric insulation materials that can withstand cryogenic operating environments while maintaining electrical reliability, mechanical stability, and manufacturing compatibility. This thesis investigates polyamide-based polymer nanocomposites as candidate HTS cable insulation materials and develops cryogenic testing platforms for evaluating thin-film dielectrics at reduced temperatures. Two silicon-based filler systems are studied: sol-gel-derived silicon dioxide (SiO 2 ) nanoparticles and polyhedral oligomeric silsesquioxane (POSS). Dielectric breakdown behavior is evaluated under DC and AC high-potential testing, while mechanical behavior is assessed through tensile testing. The results show that PA/SiO 2 nanocomposites provide the strongest overall balance of mechanical reinforcement and …


From Retrieval To Generation: Building And Evaluating An Ai Accompanist For Piano Duets With An Anticipatory Music Transformer, Sai Ruthvik Uppala Sep 2026

From Retrieval To Generation: Building And Evaluating An Ai Accompanist For Piano Duets With An Anticipatory Music Transformer, Sai Ruthvik Uppala

Masters Theses

Systems that accompany a live musician, such as ACCompanion, work by retrieval: they hold a written accompaniment and stretch its timing to follow the soloist, so they can only accompany music whose second part already exists as a score. This thesis asks whether that second part can instead be generated, and specifically whether a machine learning model can write an accompaniment for a piece whose score it has never seen. A player performs the primo, the melody; a model produces the secondo, the accompaniment; and a score follower places the generated notes against the live performance. If this works, a …


Teaching Third Graders To Read Multisyllable Words: Segmentation Versus Whole Word Reading, Jolie D. Heath Sep 2026

Teaching Third Graders To Read Multisyllable Words: Segmentation Versus Whole Word Reading, Jolie D. Heath

Dissertations, Theses, and Capstone Projects

In the early years of elementary school when children are still learning to read, they are presented with words of increased syllable length, and orthographic and morphological complexity in the texts they read.  Although multisyllabic words comprise 90% of words in the English lexicon and carry important linguistic information for expanding vocabularies and comprehension of content, few studies have focused on teaching middle elementary children to read multisyllabic words.  Many children lack strategies to identify these longer more complex words accurately and easily, leading to reading difficulties that place weaker readers at higher risk for school related problems and limit …


Social And Structural Factors In The Development Of Baltimore's Low Back Vowels, Aidan J. Malanoski Sep 2026

Social And Structural Factors In The Development Of Baltimore's Low Back Vowels, Aidan J. Malanoski

Dissertations, Theses, and Capstone Projects

This dissertation is concerned with the low back vowels of Baltimore English: what low back systems occur, and how these systems have changed among Black and white Baltimoreans. I draw on two sources of data: 48 interviews that I conducted with natives of Baltimore and its inner suburbs, and 18 oral history interviews that were conducted from 1978 to 1981. In Chapter 3, I argue for the inclusion of the pre-rhotic sets START and NORTH in typologies of English low back vowels. With these sets included, several previously unattested low back systems are found in Baltimore. These are united by …


Identifying Influential Drivers To The Utilization Of Prefabrication On Student Housing At Cal Poly: A Case Study On The Delivery Method, Dominique Giang Sep 2026

Identifying Influential Drivers To The Utilization Of Prefabrication On Student Housing At Cal Poly: A Case Study On The Delivery Method, Dominique Giang

Construction Management

As universities experience increasing enrollment and housing shortages, student housing projects require efficient delivery methods capable of meeting strict occupancy deadlines while minimizing disruption to active campus environments. This research investigates the influential drivers behind the utilization of prefabrication on an ongoing student housing project at California Polytechnic State University, San Luis Obispo. The seven-story project consists of 417 student beds and incorporates repetitive layouts and prefabricated building components. Through qualitative interviews with key project stakeholders involved in early decision-making and field execution, the study examines how project objectives, construction constraints, and delivery considerations influenced the decision to implement prefabrication. …


Quantitative Analysis Of Blue 1 Dye In Commercial Sports Drinks By Uv -Vis Spectroscopy And Hplc-Dad, Mikayla Bush Sep 2026

Quantitative Analysis Of Blue 1 Dye In Commercial Sports Drinks By Uv -Vis Spectroscopy And Hplc-Dad, Mikayla Bush

Forensic Science Master's Projects

Food dyes are natural or synthetic substances added to foods, beverages, and cosmetics to enhance color and visual appeal. Although they provide no nutritional value, they are widely used to attract consumers, particularly children. Concerns have been raised about the potential health effects of synthetic dyes, including links to hyperactivity in children, tumor formation at high doses, and possible impacts on gut and brain function. In response, regulatory efforts are ongoing. In April 2025, the U.S. Department of Health and Human Services (HHS) and the Food and Drug Administration (FDA) announced an initiative to phase out petroleum-based food dyes, including …


Sec-Saxs And Sans Analyses Of The Talin•Vinculin Complex, Gilbert Reyes Sep 2026

Sec-Saxs And Sans Analyses Of The Talin•Vinculin Complex, Gilbert Reyes

Dissertations, Theses, and Capstone Projects

Focal adhesions (FA) are integrin-based cell-matrix adhesion sites composed of adaptor proteins that facilitate the generation of traction forces important for biological functions such as cell migration, embryo development, wound healing, tissue organization and stability, and immune responses. Mature FA are observed when both autoinhibited multi-domain scaffolding protein talin and membrane-cytoskeletal protein vinculin are activated and interact thus promoting the assembly and function of FA. While research has resolved truncated sections of autoinhibited talin and recruitment of vinculin due to mechanotransduction that exposes cryptic vinculin binding sites (VBS), little is known about the global modifications of full length talin in …


Modeling And Generating Trustworthy Speech, Yuwen Yu Sep 2026

Modeling And Generating Trustworthy Speech, Yuwen Yu

Dissertations, Theses, and Capstone Projects

As virtual agents become increasingly integrated into everyday communication, trust has become essential for effective human-AI interaction. Although recent advances in natural language generation and speech synthesis have significantly improved fluency and intelligibility, most systems are not designed to control how trustworthy they are perceived. As a result, a mismatch can emerge between perceived trustworthiness and actual system capability, leading to over-trust or under-trust. While trust is critical for meaningful interaction, current text-to-speech (TTS) systems are primarily optimized for naturalness and intelligibility rather than calibrated trustworthiness.

This dissertation investigates the perceptual foundations of trust in both human and synthesized speech …


The Cross-Section Of Empirical Evidence And Personal Experience: A Deeper Look At School Resource Officers Through The Lens Of Demarcus A. Jenkins' Research On The Public Opinion Of Their Potential Removal From Public Schools, Quin Armstrong Sep 2026

The Cross-Section Of Empirical Evidence And Personal Experience: A Deeper Look At School Resource Officers Through The Lens Of Demarcus A. Jenkins' Research On The Public Opinion Of Their Potential Removal From Public Schools, Quin Armstrong

University Honors Theses

Following the 2020 Black Lives Matter and Anti-Police movements, there were many discussions across the nation about possible changes to law enforcement operations. Among these discussions included specific discussions about what to do about law enforcement officers stationed in schools. These law enforcement officers are known as school resource officers, or SROs.

The focus of this thesis is specifically on Portland, Oregon's Portland Public School (PPS) district's decision to sever ties with the Portland Police Bureau, and what may have contributed to that ultimate decision. This is accomplished through an analysis of a research paper written by fellow Criminal Justice …


“Voices Of Tomorrow”: A Youth Participatory Action Research Study Of A Middle School Advisory In An Urban Public Charter School, Seth Hull Sep 2026

“Voices Of Tomorrow”: A Youth Participatory Action Research Study Of A Middle School Advisory In An Urban Public Charter School, Seth Hull

Theses and Dissertations

Urban middle schools often grapple with how to create spaces that affirm students’ identities and foster authentic engagement within a broader landscape shaped by standardized testing and accountability pressures. This dissertation examines Youth Participatory Action Research (YPAR) and advisory as two relationally grounded practices that can address these challenges. Grounded in critical hope (Zembylas, 2013), culturally sustaining pedagogy (Paris & Alim, 2017), and community responsive education (Duncan-Andrade, 2022), the study explores the experiences of 12 middle school students who spent seven months investigating their school’s advisory program as student-researchers, as well as the findings that emerged about advisory. Data sources …


Alzheimer’S Disease And Related Dementias Risk Profiles And Health Literacy Among South Asian Seniors, Sandra A. Kennedy Sep 2026

Alzheimer’S Disease And Related Dementias Risk Profiles And Health Literacy Among South Asian Seniors, Sandra A. Kennedy

Dissertations, Theses, and Capstone Projects

Alzheimer’s Disease and Related Dementias (ADRD) pose significant health challenges globally, with South Asian seniors in the United States facing elevated risks due to high rates of cardiovascular disease, diabetes, and limited health literacy. This study assessed dementia literacy and the prevalence of cardiovascular, psychosocial, and lifestyle risk factors among South Asian seniors in New York City, utilizing community-based participatory research (CBPR) principles in collaboration with India Home, a community-based organization. Fifty-six (N=56) South Asian seniors aged 55 and older (M = 69.05, SD = 6.36), primarily of Indian or Bangladeshi origin, participated in the study. Data collection involved a …


Allyship And Affect: Qualitative Investigations Into Social Transformation, Michael Lucinda Jane Greer Sep 2026

Allyship And Affect: Qualitative Investigations Into Social Transformation, Michael Lucinda Jane Greer

Dissertations, Theses, and Capstone Projects

Allies have faced several critiques in feminist philosophy. Some have argued that they lack the requisite political interests to be motivated to dismantle the social structures from which they stand to benefit. Others have argued that the epistemic limitations resulting from their social privilege are insurmountable. Yet others have argued that allyship is too individualistic a concept, preferring a more collectivist concept like solidarity. However, there remain privileged individuals who understand themselves as complicit in perpetuating oppressive forms of life, and who wish to transform themselves and work in coalition across difference to dismantle structural oppression. How ought these individuals …


The Cranial Nerves And Electrical Stimulation, Devin K. P. Adair Sep 2026

The Cranial Nerves And Electrical Stimulation, Devin K. P. Adair

Dissertations, Theses, and Capstone Projects

Cranial nerves provide afferent pathways that enable bottom-up modulation of central autonomic and cognitive neural pathways. Because these pathways project to brainstem nuclei such as the nucleus tractus solitarius and engage neuromodulatory systems, including the locus coeruleus, electrical stimulation offers a mechanistically grounded approach to influencing brain function. This thesis tested whether active transcutaneous auricular vagus nerve stimulation (taVNS) produces physiological responses indicative of parasympathetic engagement, defined as decreases in heart rate, increases in heart rate variability, and decreases in respiration relative to a dose-matched earlobe control condition. Using cardiac and respiratory measures as physiological markers, taVNS at the tragus …


The Relationship Between Adverse Childhood Experiences, Protective And Compensatory Experiences, And Parenting Attitudes Among Fathers, Kylie Schmidt Sep 2026

The Relationship Between Adverse Childhood Experiences, Protective And Compensatory Experiences, And Parenting Attitudes Among Fathers, Kylie Schmidt

Dissertations

Adverse childhood experiences (ACEs) are defined as potentially traumatic events that occur in childhood particularly between the ages of 0 and 17 years that negatively influence long-term health, relational functioning, and parenting practices (Centers for Disease Control and Prevention, 2026; Felitti et al., 1998; Merrick et al., 2019). Conversely, protective and compensatory experiences (PACEs) have emerged as protective factors that foster resilience and possibly buffer against the adverse outcomes of ACEs (Narayan et al., 2018). As the existing research has greatly focused on mothers, little is known about how men’s early life experiences shape their parenting attitudes, particularly during the …


Cognitive-Affective And Somatic Depressive Symptom Domains Related To Psychological Mechanisms And Sociodemographic Factors, Danielle B. Hazeltine Sep 2026

Cognitive-Affective And Somatic Depressive Symptom Domains Related To Psychological Mechanisms And Sociodemographic Factors, Danielle B. Hazeltine

Dissertations, Theses, and Capstone Projects

Major depressive disorder is prevalent, chronic, and heterogeneous, including cognitive- affective (e.g., maladaptive beliefs or thinking patterns and sad mood) and somatic (e.g., fatigue, appetite, or sleep changes) symptom domains. While depression domains have been long theorized, research examining psychological mechanisms underlying this distinction is limited. Preliminary research suggests cognitive-affective symptoms relate more strongly to cognitive mechanisms (cognitive bias, perseverative thought), somatic symptoms relate more strongly to behavioral mechanisms (behavioral inhibition/activation), and gender, race, and ethnicity moderate these relationships. This study examined whether cognitive-affective and somatic symptom domains differentially relate to cognitive and behavioral mechanisms, and whether these relationships are …


Distinguishing Between Complex Post-Traumatic Stress Disorder And Post-Traumatic Stress Disorder: The Role Of Childhood Maltreatment, Catherine Harris Sep 2026

Distinguishing Between Complex Post-Traumatic Stress Disorder And Post-Traumatic Stress Disorder: The Role Of Childhood Maltreatment, Catherine Harris

Dissertations, Theses, and Capstone Projects

The current study examined whether court-substantiated childhood maltreatment may be associated with increased risk for Complex PTSD (CPTSD) and whether individuals with CPTSD and individuals with PTSD could be distinguished in terms of complex trauma exposure. Children with documented cases of abuse and neglect prior to age 11 were matched on age, race, sex, and approximate family socioeconomic status with children without documented histories of maltreatment (controls) and both groups were followed prospectively into adulthood. Participants (N = 1,196) were assessed using a DSM-III-R based structured interview of PTSD symptoms and other self-report measures of psychiatric symptoms at mean age …


Catalytic Synthesis Of Protoberberine Alkaloids And Their Evaluation As Selective Dopamine Receptor Ligands, Ashok Reddy Gudipally Sep 2026

Catalytic Synthesis Of Protoberberine Alkaloids And Their Evaluation As Selective Dopamine Receptor Ligands, Ashok Reddy Gudipally

Dissertations, Theses, and Capstone Projects

Dopamine regulates motor control, cognition, reward, motivation, and neuroendocrine signaling. Disruption of dopaminergic neurotransmission is closely linked to central nervous system disorders, including Parkinson’s disease, schizophrenia, addiction, and related neuropsychiatric conditions. Because these functions are mediated by multiple dopamine receptor subtypes with distinct roles in physiology and disease, the discovery of subtype-selective ligands remains an important goal in neuropharmacology. Within this context, protoberberine alkaloids, particularly tetrahydroprotoberberines (THPBs), are attractive molecular frameworks because they combine structural complexity with broad biological relevance, including measurable activity in CNS-related diseases. Prior work from our laboratory and others established (–)-stepholidine (1.60) as an important lead …


Vibe Diggers: The Sampling Of Brazilian Music In Hip-Hop, Romulo De Carvalho Moraes Barbosa Sep 2026

Vibe Diggers: The Sampling Of Brazilian Music In Hip-Hop, Romulo De Carvalho Moraes Barbosa

Dissertations, Theses, and Capstone Projects

This dissertation investigates the trend of musical borrowings of 1970s MPB (música popular brasileira) by contemporary American hip-hop producers, especially in terms of what they have called a “Brazilian vibe.” A lot has been said about sampling already from legal, sociological, and historical points of view, but less has been said about its aesthetic procedures, and even less about the wider implications of a tendency for using transnational sources. In the case of MPB, hip-hop artists seem to understand the music they sample through an often vague, intuitive representation, which fuses qualities of those recordings with an intersubjective mood, a …


Possibilities Of Being: Black Women's Storytelling As Archival Undoing, Dasharah Green Sep 2026

Possibilities Of Being: Black Women's Storytelling As Archival Undoing, Dasharah Green

Dissertations, Theses, and Capstone Projects

This dissertation constructs a discursive genealogy of Black women’s storytelling, positioning its art and aesthetics as a form of colonial archival undoing. Each chapter explores how transmission and documentation can transform—and circumvent—traditional colonial archives. Beginning at the start of the twentieth-century to present, this project traces the discursive legacies of Zora Neale Hurston, Audre Lorde, Michelle Cliff, and Staceyann Chin, examining each writer as a site of becoming as they individually (and collectively) seek to articulate an expansive idea of a Black world that constitutes a broader understanding of Black freedom. They each share a common goal of creating a …


Social Media-Based Social Comparisons Among Socially Anxious Young Adults: The Role Of Cognitive Reappraisal, Jennifer L. De Rutte Sep 2026

Social Media-Based Social Comparisons Among Socially Anxious Young Adults: The Role Of Cognitive Reappraisal, Jennifer L. De Rutte

Dissertations, Theses, and Capstone Projects

Social media is a central context for social interaction and self-evaluation among young adults. For those with elevated social anxiety, these environments may be especially salient because they provide frequent opportunities for social comparison. Although upward social comparison on social media has been linked to poorer emotional outcomes, less is known about its experimental effects among socially anxious young adults or whether upward and downward comparison have distinct effects that extend to later socially evaluative situations. The present study examined these questions in 84 socially anxious young adults randomly assigned to view simulated Instagram feeds eliciting upward comparison, downward comparison, …


Intimate Partner Violence And Emotion Regulation Among Emerging Adults: Investigating The Roles Of Dispositional Mindfulness And Executive Function In The Context Of A Laboratory-Induced Stress Paradigm, Mikell Bursky Sep 2026

Intimate Partner Violence And Emotion Regulation Among Emerging Adults: Investigating The Roles Of Dispositional Mindfulness And Executive Function In The Context Of A Laboratory-Induced Stress Paradigm, Mikell Bursky

Dissertations, Theses, and Capstone Projects

Intimate Partner Violence (IPV) is a major public health concern that impacts an estimated 10 million men and women in the United States annually. IPV refers to a range of physical, sexual or psychological forms of aggression committed against a current or former romantic partner in the context of a relationship. The highest rates of IPV are observed in emerging adulthood, a developmental period between the ages of 18 to 25 that is significant for the transition from adolescence into adulthood, and the establishment of first meaningful intimate relationships. Although distal risk factors for IPV such as violence in the …


Model-Theoretic Arguments In Philosophy, Peter Susanszky Sep 2026

Model-Theoretic Arguments In Philosophy, Peter Susanszky

Dissertations, Theses, and Capstone Projects

This dissertation is on model-theoretic arguments in philosophy, especially those of Quine, Davidson, and Putnam. In the first part, to ground the debate, I give a rigorous introduction to the salient parts of first-order model theory. I start the second part by giving an introduction to Quine's philosophy, and how the model-theoretic arguments fit into it. After considering how Donald Davidson adopted the Quinean lesson, I move on to Putnam's model-theoretic arguments. Putnam's spin on these model-theoretic considerations significantly departs from Quine and Davidson, while retaining many of the core ideas. Most importantly, I argue that the target of Putnam's …


Shifting To Using Desmos Or Geogebra Graphing Calculators In High School Mathematics Classrooms, Nancy Lin Sep 2026

Shifting To Using Desmos Or Geogebra Graphing Calculators In High School Mathematics Classrooms, Nancy Lin

Dissertations, Theses, and Capstone Projects

Most high school math classrooms in Long Island use the Texas Instruments TI-84+ CE graphing calculator in the three Regents math courses. Texas Instruments holds approximately 80% of the market share of the international graphing calculator market. At a manufacturer's suggested retail price of $150 per TI-84+ CE, an inequitable situation exists for math learning, as underfunded schools and students from lower socioeconomic backgrounds cannot afford to purchase one for home use. Such students have less experience using the handheld graphing calculator when they take high-stakes math exams. Through case studies of four suburban school districts in New York that …
