Designing Inclusive Stem Curricula: A Design-Based Study Of Teacher Learning And A Queer Inclusive Framework, Kyle Nolting

Electronic Theses and Dissertations

STEM (Science, Technology, Engineering, and Mathematics) education has historically marginalized queer identities, shaping inaccurate curricula and fostering unwelcoming classroom environments. To address this, my research uses design-based research to investigate the design of queer-inclusive STEM curricular resources. I partnered with in-service secondary STEM teachers amidst a series of professional development courses to co-create curricular resources. My research is grounded in queer theory, using a Gender Inclusive Framework to collaboratively develop inclusive design principles. My findings revealed a strong desire by teachers for more authentic and fluid representations of gender and sexuality in STEM curricula, particularly beyond the biological science discipline. …

The Development And Validation Of Gains-Id, A Guidebook For Adapting Intervention Sessions For Students With Intellectual Disability, Kayla Mccreadie

Electronic Theses and Dissertations

Targeted interventions can equip students with intellectual disabilities (ID) with essential academic skills that support positive post-secondary outcomes. However, the lack of interventions specifically designed for this population creates barriers to equitable education. Until more interventions are developed, educators may benefit from resources that help adapt evidence-based practices to meet the needs of students with IDD.

The first manuscript introduces GAINS-ID (Guide for Adapting INtervention Sessions for Intellectual Disabilities). Based on best practices and Universal Design for Learning (UDL), the guide offers examples of adaptations to various intervention components—such as time, materials, environment, …

Exploring The Impact Of Artificial Intelligence Tools On Special Education Teachers’ Workload And Burnout In Colorado: A Qualitative Phenomenological Study, Rawa Suhail Abu Alsamah

A Policy Analysis Of Higher Education Support For Foster Youth In The Colorado Child Welfare System, Krystal Robles

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

This policy analysis examines how two Colorado laws, House Bill 22-1374 (Foster Care Success Act), and Senate Bill 22-008 (Higher Education Support for Foster Youth), aim to improve educational outcomes and long-term stability for youth who age out of the foster care system. Critical Policy Analysis (CPA) and Resilience Theory are used in this paper to examine how these policies address systemic inequities, promote resilience, and offer protective factors that support educational attainment. Using policy review, state policy comparison, stakeholder interviews, and community perspectives, I evaluated how the implementation, effectiveness, and limitations of these bills shape real-world impact. The findings …

A Bibliometric And Descriptive Analysis Of The Disciplinary Affiliations Of Research About Students With Disabilities In College-Level Science Education, Tongriang N. Daspan M.Ed, Aaron C. Wenger Phd, Brandy Pleasants Phd

Journal of Science Education for Students with Disabilities

Despite the global emphasis on equity and the need for inclusive science education, students with disabilities (SwDs) encounter persistent barriers in college-level science learning environments. While prior research has explored isolated challenges faced by SwDs, few studies have examined how these challenges vary across science disciplines. Yet, science education research is often situated within distinct disciplinary traditions, such as biology education research or geoscience education research, known collectively as Discipline-Based Education Research (DBER). Understanding the disciplinary distribution of research on SwDs is essential to identifying gaps and fostering cross-disciplinary learning. This study maps trends and patterns in the disciplinary affiliations …

Learning Engineering Design Through Making: Affordances Of A Nonformal Tinkering Environment, Cristina Simarro, Digna Couso

Journal of Pre-College Engineering Education Research (J-PEER)

The maker movement has been increasingly adopted as a means for promoting interdisciplinary approaches to STEM learning. However, empirical evidence regarding how making supports the development of engineering design skills remains limited and inconclusive. This study provides an in-depth examination of a nonformal educational initiative grounded in tinkering, a creative and improvisational subset of making, by analyzing the tasks undertaken by primary school children in a tinkering setting. Our results confirm the capacity of tinkering activities to foster specific engineering design practices and elucidate the interrelationships between them. Furthermore, the findings highlight the potential of such approaches to facilitate the …

Looking Beneath The Surface: Understanding Fetal Alcohol Spectrum Disorder Through The Caregiver’S Lens—Support, Advocacy, And Self-Care, Melissa Fredin

Master of Arts in Human Services

Fetal Alcohol Spectrum Disorder (FASD) is a lifelong neurodevelopmental disability resulting from prenatal alcohol exposure that can affect cognitive functioning, adaptive skills, communication, emotional regulation, and daily living abilities. Individuals with FASD and their caregivers often face complex challenges while navigating behavioral, educational, healthcare, human service, and criminal justice systems. Although awareness of FASD continues to increase, gaps remain in caregiver education, professional understanding, and access to coordinated, trauma-informed supports. The literature indicates that caregiver education is central to improving outcomes for individuals with FASD and is associated with stronger advocacy, more effective support strategies, greater caregiver resilience, and improved …
