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.

基于微课视频的在线课程模式：以CAD几何建模课程为例

近年来，互联网已成为大学重要的教学工具。但是，现有的在线课程模式仍然存在一些明显的缺点，例如学习约束少、互动少、氛围少。为了提高在线课程质量，本文介绍了一种以教师为主导的自适应学习的在线翻转课堂。在线课堂环境包括社区以及知识、学习者和评估中心。此外，我们提出了一种使用认知心理学理论的远程学习模式，包括微课、课堂互动、课后练习和编程培训。以CAD几何建模课程为例，该方法已应用于2020年春季学期三个不同学习能力的教学班级。两种官网大数据评估方式均表明，在线课程模式优于其他课程模式。因此，我们改进的在线课程模式高效且深受学生欢迎。
