This chapter explores the concept of adaptive interventions in learning engagement, focusing on the use of AI tools to enhance learning outcomes. Through the introduction of relevant case studies, systematic empirical research demonstrates how AI technology empowers research on learning engagement by enabling adaptive interventions across the multidimensional states of learners’ cognition, emotion, and behavior, resulting in effective improvements in students’ learning outcomes. In conclusion, the chapter highlights the power of AI in facilitating adaptive interventions in learning engagement, providing a foundation for future developments in adaptive learning interventions that meet the diverse needs of students.
