With the application of information technology in higher education, traditional university mathematics classrooms are teacher-led. Due to problems in student participation, independent learning ability and classroom efficiency, it is difficult to adapt to the requirements of comprehensive ability cultivation in the new era. Based on this situation, this article carries out the work of building a hybrid teaching system that integrates online and offline. By reconstructing the course structure, teaching content and learning tasks, the teaching is divided into three stages: "carrying out independent learning before class, conducting interactive exploration in class, and implementing consolidation and expansion after class". It relies on the online platform to integrate micro-courses, question banks and interactive tools to achieve resource release, progress tracking and data recording. At the same time, we build a learning task chain and a multi-dimensional evaluation mechanism to incorporate preview, classroom participation and learning results into the whole process management to improve the level of teaching refinement. Experiments show that blended teaching increases the online homework completion rate from 78.6% to 93.7%, and the classroom interaction participation rate from 42.3% to 68.5%. The degree of learning participation and effect are significantly better than the traditional model.
