There are problems of fragmented knowledge points and a disconnection between theory and practice in the curriculum module of the polymer materials and engineering major. This research–guided by the “new engineering” initiative and aligned with the latest polymer industry trends–has established a “three-tier” major course module. By integrating teaching content

optimizing practice components

reforming teaching methods and strategies

and deep integration with curriculum-based ideological and political education

a systematic reconstruction of the polymer major core courses of the School of Materials Science and Engineering at Zhengzhou University was accomplished. The results of this study show that the reform efficiently enhances students’ engineering practice capability and innovative literacy

leading to fruitful teaching achievements and offering valuable experience for developing similar major course clusters.
