In the context of diverse student sources in vocational colleges, this paper proposed and implemented multi-level teaching reforms based on digital technology. A multi-level teaching concept centered on proactive choice has been proposed to avoid the inherent flaws of traditional 'tiered teaching'. Building a hierarchical and categorized digital teaching resource library based on the Chaoxing Learning platform. Form a blended teaching model that integrates online and offline learning, making comprehensive use of digital tools such as GeoGebra, MATLAB, and AI intelligent. In addition, a multidimensional formative evaluation mechanism based on learning behavior data has been established. Practice has shown that this reform effectively stimulates students’ intrinsic motivation for learning and improves their academic performance and competition results. A replicable and scalable digital teaching model for vocational college mathematics has been formed, which can provide practical reference for the reform of public basic courses in similar vocational colleges.
