Abstract：

Focusing on the course Linux Operating System Application, this paper explores the integrated application of blended online-offline teaching and the Problem-Based Learning (PBL) method. By constructing a three-dimensional teaching system consisting of online pre-class preview, offline in-class practice, and online post-class expansion, a full-process teaching scheme covering problem introduction, group collaboration, practical operation, and achievement presentation is designed, with the project of DNS server configuration as a case study. Practice shows that this model significantly improves students' practical operation ability and problem-solving skills, effectively stimulates their learning interest, and provides a replicable practical path for the teaching reform of operating system-related courses.
