Abstract: As digital education advances, digital empowerment has become a key driver in teaching reform and curriculum development. This article examines how digital tools can enhance graduate professional courses. To address common teaching challenges, such as rigid methods, weak ideological-political integration, theory-practice gaps, and outdated content, this paper systematically explores the implementation path of high-quality development of courses driven by digitalization, and constructs a core reform framework of “theory experiment ideology case” “four in one” . Using the course equipment condition monitoring and diagnosis as an example, we developed digital teaching resources, strengthened ideological-political elements, introduced digital lab platforms, and incorporated real engineering cases. These steps have improved teaching outcomes and may serve as a reference for similar course reforms.
