Abstract: This study aims to explore a new teaching model for the internship for polymer materials major based on virtual simulation and to assess its impact on student learning outcomes. We designed a new teaching model that integrates virtual simulation experiments with practical internships by incorporating virtual simulation technology into the curriculum. Through questionnaire surveys and student performance assessments, we compared student learning outcomes before and after its implementation. The research results indicate that compared to traditional internship models, the virtual simulation-based approach can significantly improve students’ learning motivation and internship effectiveness, with an average excellence rate of 89.5% across various assessments. Therefore, the exploration and advancement of this new teaching model are of great theoretical and practical significance for improving the teaching effectiveness of the internship for the polymer materials major.
