Systematic Reform Path for EMI Courses: A Case Study of Principles of Metal Cutting and Machine Tools

To meet the demand for cultivating internationalized talents in Emerging Engineering Education, this paper addresses five major issues in the English as medium of instruction (EMI) course "Principles of Metal Cutting and Machine Tools": cognitive overload, fragmented content, technological obsolescence, weak practical training, and superficial ideological-political integration. A "four-dimensional driven" reform model is proposed: (1) Cognitive Load Reduction Mechanism: Constructs a three-tiered framework—"Pre-digested Glossary → Dynamic Visualization Resources → Modular Teaching Aids"; (2) Knowledge Topology Restructuring: Establishes a 3D mapping of "Function → Structure → Implementation," integrates universal tool design principles, and embeds intelligent manufacturing modules; (3) Deep Ideological-Political Integration: Designs a three-stage permeation model—"Technical Ethics → Traditional Wisdom → Engineering Standards"; (4) Virtual-Real Collaborative Practice: Develops an ability chain of "Basic Experiments → Comprehensive Training → Industrial Projects." This model provides a standardized reform framework for high-practicality EMI engineering courses, fostering globally competitive emerging engineering talents.
