This chapter explores the transformative potential of generative artificial intelligence (AI) in online education, particularly within learning management systems (LMS). By leveraging AI to create dynamic instructional content—including videos, images, and texts—this chapter highlights how these tools can enhance creativity and engagement in digital learning environments. A focal point is the innovative use of video avatars, which utilize generative AI to produce interactive and personalized teaching personas. These avatars offer a scalable and individualized alternative to conventional pedagogical methods. Additionally, the chapter examines AI's role in designing assignments, rubrics, and interactive simulations aimed at improving student engagement and learning outcomes. AI-assisted grading is presented to reduce instructor workload while providing personalized feedback. The ability of AI to autonomously analyse course objectives and suggest relevant assignments and evaluation metrics is also investigated. The integration of generative AI technologies, particularly video avatars, presents a significant opportunity to revolutionize the delivery and effectiveness of online education. This chapter posits that such advancements not only create a more engaging learning environment but also substantially elevate the quality of instruction and educational outcomes.
