Research and Practice on Teaching Reform of Operating System Principles Course based on TBL Teaching Model

This paper takes the "Operating System Principles" course for the Internet of Things Engineering major in the School of Computer Science as the research subject. Addressing issues in traditional teaching such as passive student learning, disconnection between theory and practice, and insufficient teamwork skills, the TBL (Team-Based Learning)teaching model was introduced. A systematic reform was implemented across four aspects: teaching objectives, teaching content, teaching activities, and teaching evaluation. Through a one-semester teaching practice, comparative data from two rounds of classes were collected. Using a mixed-methods research approach combining quantitative and qualitative analysis, the impact of the TBL model on students' academic performance, practical abilities, teamwork skills, and learning attitudes was thoroughly analyzed. The research indicates that the experimental class significantly outperformed the control class in final exam scores, project completion quality, and teamwork skills(p<0.05).Student satisfaction with the TBL teaching model reached 89.7%,with the highest ratings given for "increasing learning interest", "enhancing practical ability" and "promoting teamwork". This paper also details the specific instructional case design, implementation process, encountered problems, and solutions under the TBL model, providing a referential path and practical basis for teaching reform in core computer science courses.
