This study investigates the potential of Artificial Intelligence (AI) to enhance the quality of physics education in Vietnamese high schools, aligning with the competency-based approach of the General Education Program 2018. The research employed a mixed-methods approach, surveying 82 physics teachers to assess their awareness, attitudes, and current application of AI in teaching. The findings reveal that while teachers recognize the potential benefits of AI, such as personalized learning and workload reduction, significant challenges remain, including limited AI knowledge, lack of infrastructure, and appropriate AI tools. The study suggests targeted training programs for teachers, focusing on popular AI applications like ChatGPT and Gemini and promoting active teaching models integrated with AI. It recommends further research to evaluate the practical effectiveness of AI in physics teaching and its impact on student learning outcomes. The study concludes that AI can significantly transform physics education by empowering teachers and creating engaging student learning experiences.
