The emergence of MOOC (massive open online courses) is gradually changing the way college students learn. At the same time, it also provides them with more abundant learning resources. Based on the characteristics of the course of basic principles of civil engineering construction and the content of MOOC construction, this paper introduces the dynamic construction of practical resources in the MOOC construction of this course, which includes videos of construction process, animation of construction technology, photographs of construction sites and engineering cases, etc. The process of setting up engineering case base is mainly introduced. It also discusses how to use the internet to optimize the teaching process and improve the teaching efficiency, which has positive significance for the teaching reform in civil engineering courses.
