Analysis of the Application Effect of Project-Based Teaching Method in the Machining Process Course

Abstract

The hierarchical progressive knowledge system and implicit skill composition of the Machining Process Course require a situation-driven mechanism for the teaching method. The Project-Based Teaching Method establishes a dynamic coupling between task situations and cognitive structures through a five-stage nonlinear path, forming a many-to-many mapping with the process capability objectives. This method drives the structured reorganization of knowledge points along the processing flow, strengthens the logic of multi-attribute decision-making, and prompts learners to develop parameter correction strategies through cognitive conflict. Regarding the application effects, this paper proposes a quantitative characterization system that includes knowledge retention rate, transfer efficiency, error tracing, and stability judgment criteria, and divides the optimization magnitude into three innovation levels: the parameter level, the process level, and the principle level.
