Over recent years, the Internet has become an important teaching tool in universities. However, existing online course modes still have some obvious disadvantages, such as fewer learning restraints, interactions, and atmosphere. To improve online course quality, this article presents an online flip classroom with teacher‐led adaptive learning. The online classroom environment includes community as well as knowledge, learner, and assessment centers. Furthermore, we proposed a remote learning mode that uses theories of cognitive psychology and includes microlectures, class interactions, exercises after class, and programming training. Using CAD geometric modeling course as an example, the method has been applied for three teaching classes with different studying abilities in the spring semester in 2020. Two official network big data assessment methods have shown that the online course mode is better than other course modes. Consequently, our improved online course mode is efficient and popular with students.
