“Plastic Processing Technology” course occupies a core position in the curriculum of the polymer materials and engineering major. Traditional teaching methods have the problem of insufficient connection between theory and practice

making it difficult to achieve ideal results. Therefore

problem-driven teaching methods are introduced into “Plastic Processing Technology” course. Based on the authors’ years of teaching practice experience

the design is carried out from two aspects: selection of content and design of problems. The teaching content is divided into three major modules: process physics and chemistry

raw material selection and configuration

and major molding processes

focusing on the relationship between plastics

plastic parts

equipment

and processes

and making appropriate choices. The design of problems involves setting a large question for each class

introducing necessary knowledge points around completing it

and then using small questions for classroom discussions to test learning effectiveness. By continuously improving teaching design and closely linking key molding technology issues with theoretical knowledge

it is preliminarily indicated that the teaching effectiveness of “Plastic Processing Technology” courses can be significantly enhanced.
