Educational Leadership's Role In Understanding Nil Policy Perceptions Among College Football Players, Carlton Rice Dec 2025

Educational Leadership's Role In Understanding Nil Policy Perceptions Among College Football Players, Carlton Rice

Tennessee State University Alumni Theses and Dissertations

This study examined educational leadership's role in understanding Name, Image, and Likeness (NIL) policy perceptions among college football players at an American Athletic Conference institution. Using Expectancy-Value Theory as the theoretical framework, the research explored how educational leaders interpret and communicate NIL policies to student-athletes, assessed student-athlete perceptions of leadership effectiveness, and investigated how leadership experiences influence attitudes toward NIL policies. The mixed-methods study surveyed 97 college football student-athletes and conducted interviews with athletic administrators. Key findings revealed a moderately positive correlation (r=.340, p<.001) between administrative support and student-athlete knowledge of NIL policies, demonstrating that institutional investment in educational support directly impacts policy comprehension. The research found that 67% of student-athletes indicated NIL opportunities would influence their school choice decisions, fundamentally altering recruitment dynamics. Additionally, 57.7% of participants agreed that NIL affects team culture, though responses indicated this impact is highly contextual and dependent on institutional management. The study identified significant variation in educational leadership approaches across institutions, with some employing dedicated NIL strategy teams while others integrate responsibilities within existing compliance departments. A notable gap emerged between student-athlete NIL expectations and institutional support, with many athletes reporting they "do everything on our own." For higher education institutions, findings suggest the need for comprehensive NIL education programs extending beyond basic compliance to include financial literacy, contract negotiation, and personal branding. Institutions should develop values-based frameworks aligning NIL opportunities with institutional missions while protecting student-athlete interests. The research contributes valuable insights for navigating the evolving NIL landscape while supporting student-athlete success.

Cross-Domain Transfer Learning Of Tabular Data With Heterogeneous Feature Spaces, Kazi Fuad Bin Akhter Dec 2025

Cross-Domain Transfer Learning Of Tabular Data With Heterogeneous Feature Spaces, Kazi Fuad Bin Akhter

Tennessee State University Alumni Theses and Dissertations

Transfer learning is a cornerstone of artificial intelligence (AI), enabling the learning of new domains with limited labeled data by reusing knowledge from large-scale foundation models. Transfer learning has achieved remarkable success with vision and language models due to the homogeneity in image and text data. In contrast, a heterogeneous feature space, structured in rows and columns as tabular data, remains underexplored in the transfer-learning literature. The inductive bias of tabular data with heterogeneous feature spaces from disparate application domains is very different from image and text data, which complicates transfer learning. Several recent studies have attempted within-domain and limited …

The Impact Of Teacher Effectiveness Factors On Student Achievement: A Case Study, Renita Joy Perkins Dec 2025

The Impact Of Teacher Effectiveness Factors On Student Achievement: A Case Study, Renita Joy Perkins

Tennessee State University Alumni Theses and Dissertations

This quantitative, correlational study examined the relationship between teacher, evaluation scores and student achievement using Tennessee's Educator Acceleration Model (TEAM) evaluation system at Spencer Elementary School in rural Van Buren County. The study analyzed data from nine teachers across grades 3-5 and 150 students, investigating correlations between TEAM evaluation scores, Level of Effectiveness (LOE) ratings, and student performance on Tennessee Ready assessments in mathematics, English Language Arts, and science. Key findings revealed a counterintuitive experience-performance paradox: while teacher years of experience positively correlated with evaluation scores (r=.422, p<.001) and LOE ratings (r=.132, p=.024), it negatively correlated with student English Language Arts achievement (r=- .174, p=.039). The study demonstrated strong internal consistency within the TEAM evaluation system, with significant correlations between LOE scores and teacher evaluation ratings (r=.375, p<.001). However, only weak correlations emerged between teacher evaluation scores and student achievement outcomes, with a slight positive relationship found only in English Language Arts (r=.165, p=.049). The research revealed robust cross-subject correlations in student achievement (r=.706, p<.001), suggesting that effective teaching impacts learning holistically rather than in subject specific ways. These findings challenge assumptions about the predictive validity of observation-based evaluation systems and highlight the complexity of measuring teaching effectiveness. Implications for educational leaders include reconsidering the relationship between teacher experience and effectiveness, implementing differentiated professional development based on evaluation data rather than years of service, and developing more nuanced approaches to using evaluation systems that integrate multiple measures of teacher impact on student learning outcomes.
