Learner engagement is essential for positive student learning experiences and outcomes. While the higher education sector has accumulated years of experience with learner engagement with conventional face-to-face instruction, it is also placing increasingly more emphasis on the combination of in-person and online teaching and learning (T&L) activities, which enhances T&L in multiple ways. Promoting and supporting learner engagement in blended learning environment is receiving greater attention and scrutiny in recent years. This keynote presentation will be situated in an AI-infused T&L landscape: the speaker will survey recent scholarship on generative artificial intelligence and blended learning and share her insights into strategies for delivering blended learning to maximize the benefit for instructors and learners in the emerging digital learning environments of higher education.
