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 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 included videos of construction process, animation of construction technology, photographs of construction sites and engineering case study, etc. The process of setting up the 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 a certain reference value for the teaching reform in civil engineering courses.
