The integration of Artificial Intelligence (AI) in education is rapidly gaining attention as a transformative force in enhancing student learning outcomes globally. In the context of Nigerian higher education, this study explores the potential of AI tools, such as AI-based tutoring systems, automated grading systems, and personalized learning platforms, in improving the academic performance of undergraduate students. Data were collected through a mixed-methods approach, including surveys and interviews with 500 students, 50 faculty members, and educational technologists across five Nigerian institutions. The findings reveal that there is significant main effect of treatment (AI-based tutoring systems, and Automated grading systems) on Learning outcomes of Nigerian Undergraduate (F(2, 50) = 43.225, p <.05,?2=.634) and there was significant main effect of intelligence on Learning outcomes of Nigerian Undergraduate (F(2, 50) = 10.711, p<.05,?2=.277) result showed that there was significant relationship between Personalized learning platforms and learning outcomes among undergraduate students (r = .421, N= 550, p <.05), The findings reveal that AI tools significantly contributed to improved student learning outcomes, particularly in courses with high dropout rates and large class sizes. However, challenges such as limited infrastructure, digital literacy, and resistance to change were identified as barriers to successful AI integration. The study concludes that while AI presents a transformative opportunity to enhance educational outcomes, its effective implementation in Nigerian higher education requires addressing technological and institutional challenges.
