Surveying Secondary Ela Teachers’ Engagement With Ai-Powered Tools For Classroom Assessment, Mona Alrashidi

USF Tampa Graduate Theses and Dissertations

The integration of Artificial Intelligence (AI) presents profound challenges andpossibilities for educational assessment, particularly in English Language Arts (ELA), where AI- powered tools can generate the very linguistic products traditionally used as evidence of student learning. While scholarship has primarily explored theoretical frameworks and broad perceptions, a critical gap remains in understanding how secondary ELA teachers navigate and report AI integration within formative assessment workflows. This understanding is essential: formative assessment has been recommended as a strategy to mitigate AI-related challenges by prioritizing learning processes over products. Yet empirical evidence of teachers’ practices remains limited.

Enhancing Nitrogen Removal In High Permeability Bioretention Media: The Combined Role Of Biochar, Wood Chips And Hydraulic Design, Joshelyn Guimaray

USF Tampa Graduate Theses and Dissertations

Urban stormwater runoff can transport high nutrient loads to receiving waters, leading toeutrophication, harmful algal blooms, and the formation of hypoxic zones. Bioretention systems are a form of green infrastructure designed to mitigate these impacts, but their application in dense, ultra-urban environments is often limited by large land area requirements. This has led to the adoption of high permeability media (HPM) to accommodate higher hydraulic loading rates (HLRs) and reduce the system footprint. However, conventional HPM systems often show inconsistent removal of dissolved nitrogen species due to short hydraulic retention times (HRTs), a lack of organic carbon, and insufficient anoxic …

Identifying B-Vitamin Requirements And Phycosphere Interactions For The Hab-Forming Dinoflagellate, Pyrodinium Bahamense Var. Bahamense, Lydia A. Ruggles

USF Tampa Graduate Theses and Dissertations

Harmful Algal Blooms (HAB) negatively affect economies, ecosystems, and public health through mass proliferation and toxin production. The HAB species, Pyrodinium bahamense var. bahamense, is a saxitoxin-producing dinoflagellate found in tropical and subtropical estuarine waters globally. In two Florida estuaries, Old Tampa Bay and the Indian River Lagoon, P. bahamense is a recurrent HAB species, and the exact timing and intensity of bloom peaks in these estuaries vary interannually. Factors that are suspected to contribute to blooms include temperature, residence times, nutrients, and salinity. However, many HAB dinoflagellates require vitamin B12 for growth and bloom development. Thus, B12 may influence …

Connectedness And Belonging: An Autoethnography About Military Veteran Transition, Benjamin A. Smet

USF Tampa Graduate Theses and Dissertations

Military veterans often face profound challenges transitioning to civilian life, yet prevailing narratives focus narrowly on PTSD and combat trauma. This dissertation uses autoethnography to broaden that view, blending personal narrative with theory to explore seven interrelated transition stressors: grief and bereavement, loss of military identity, autobiographical memory, service-connected nostalgia, moral injury, stereotype threat, and socialized masculinity and stoicism. These layered stories illuminate the cultural, emotional, and relational dimensions of transition, showing how isolation, disconnection, and loss of belonging shape veteran experiences as deeply as trauma. The analysis demonstrates that healing emerges not from prescriptive programs but from relational practices …
