To meet the needs of engineering course learners' professional courses and effectively improve the quality of undergraduate teaching, the online platform was used for teaching practices for undergraduate education. In this study, it is explored the independent and innovative learning mode of professional courses based on the course platform. It makes a dialectical analysis of the course mode, students' autonomous learning performance, and course feedback. The practices show that combining various curriculum resources and online curriculum platforms makes it convenient to capture students' learning focus in each teaching link, effectively improving students' learning efficiency and promoting classroom teaching organization. Highlighting the cultivation of students' independent innovation ability in new engineering education will help to cultivate top-notch talents more effectively and meet the needs of social and economic sustainable development.
