Abstract: In the digital intelligence era, the rapid development of online education has posed new challenges to the traditional experimental teaching mode. Through the integration of high-quality experimental teaching resources and the establishment of a cloud-based experimental teaching resource repository, this study constructs a digital and smart experimental teaching mode. The smart experimental classroom, created through the integration of five dimensions of smart thought, smart mode, smart environment, smart assessment and smart faculty, realizes efficient aggregation and sharing of teaching resources. The digital and smart experimental teaching emphasizes the organic unity of knowledge transmission and value guidance, effectively highlighting students’ central role, strengthening the cultivation of their autonomous learning ability and innovative thinking, promoting the achievement of curriculum objectives, and providing a valuable reference for the teaching reform of experimental courses in engineering disciplines.
