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

Abstract

The course of the Machining Process has a hierarchical progressive knowledge system and implicit skill composition, so a situation-based teaching method should be used. The five steps of Project-Based Teaching can form a good link between the situation of a task and cognitive structure, and they are many-to-many mapped with process capability goals. Therefore, the knowledge points will be organised systematically in the processing path, the logic of multi-attribute decision-making will be strengthened, and learners will be motivated to develop parameter correction strategies through cognitive conflict. In terms of the effect of application, this paper offers a quantitative characterisation system for the three problems of knowledge retention rate, transfer efficiency, error tracing and stability judgment criteria, and the three levels of optimisation magnitude are the parameter level, the process level and the principle level.
