Abstract: In response to the problems of theoretical and practical disconnection, low student participation, and limited experimental resources in the teaching of mineral petrology courses in vocational colleges, this article constructs a“online+offline”hybrid teaching mode with the Learning Platform as the core. By integrating digital resources, optimizing curriculum design, strengthening process assessment, and combining the Outcome-Based Education (OBE) concept, we explore effective ways to enhance students'self-learning ability and practical skills. Practice has shown that this model significantly improves teaching efficiency and students'comprehensive literacy, providing reference for the reform of geological courses in higher vocational education.
