Aimed at cultivating application-oriented engineering talents

this paper reports a digital-intelligent teaching reform of the course “Polymer Physics”. To solve the problems of heterogeneous student backgrounds

abstract content and insufficient interaction

a three-dimensional resource system centered on a knowledge graph was constructed. On this basis

a intelligent teaching system was employed to implement an innovative “6I blended teaching model”. An AI teaching assistant was introduced to provide personalized learning support and real-time learning analytics

which markedly improved instructional precision and student engagement. Digital intelligent evaluation of course objective attainment demonstrates significant progress in students’ knowledge mastery

competence development and literacy enhancement. The practice proves that the digital intelligent reform effectively upgrades teaching quality and offers a reproducible paradigm for the transformation of engineering major courses.
