With the rapid development of Artificial Intelligence (AI) and the digital economy, the teaching in the big data technology major is facing dilemmas in terms of concepts, content, methods, etc. To address these problems, this paper deeply integrates the concept of Outcome-Based Education (OBE) with AI to reconstruct teaching. AI cases are integrated into teaching to align with industry needs, cultivating students' multi-faceted capabilities and correct professional ethics. At the same time, curriculum ideology and politics are improved, AI is used to optimize all aspects of teaching, and interactive and project-based teaching are employed to stimulate interest. Practice in the course of Big Data Preprocessing Technology shows that this model enhances learning interest, significantly improves students' knowledge, skills, and comprehensive quality, and ensures the steady improvement of teaching quality.
