This paper takes the operating system course as the research object. Aiming at the problems such as fragmented knowledge and single learning path existing in the traditional teaching mode

an intelligent teaching scheme based on the Chaoxing Learning Pass platform to construct the course knowledge graph is proposed. By structuring course resources through the Chaoxing platform

a multi-dimensional knowledge graph system covering core concepts such as process management

memory allocation

file systems

and device control

key algorithms

and typical application scenarios is established. Relying on the learning situation analysis function of the Learning Pass platform

students' learning behaviors and mastery situations are dynamically tracked. This model enhances students' understanding of the intrinsic connections of the system mechanism through a visual knowledge network

dynamically diagnoses weak links in knowledge

and precisely supports teaching intervention. At the same time

integrate online resources

introduce practical cases related to operating systems

expand the engineering perspective

stimulate students' interest

promote independent exploration

and effectively improve teaching efficiency and learning outcomes.
