Abstract: In the context of rapid advancements in information technology, the application of digital technology in higher education has become a crucial means of driving educational reform. Addressing issues such as unequal resource distribution and low teaching efficiency in traditional teaching models, the paper proposes the “6i” digital education application and support service system, encompassing teaching (iLearn), learning (iSocial), evaluation (iSense), management (iEdu), services (iHelp), and environment (iMeta). Through specific measures such as the construction of three types of classrooms, the development of digital teaching resources, teaching model reform, digital teaching quality management, and the exploration of new digital technology applications in teaching, Jilin University has achieved a digital transformation of teaching resources and innovation in teaching models. The results indicate that the application of digital technology significantly enhances teaching quality and learning outcomes, providing students with more opportunities for autonomous and personalized learning. The findings of this study offer valuable insights for other universities in promoting digital transformation in education, helping to build a more open, efficient, and intelligent educational system, and advancing high-quality educational development.
