MOOC的出现正越来越多地改变大学生们的学习方式，同时也给他们提供了更丰富的学习资源。本文在结合《土木工程施工基本原理》课程特点和MOOC建设内容的基础上，介绍了该课程MOOC建设中关于实践资源的动态建设过程，它包括了施工过程的视频、施工工艺的动画、施工现场的照片以及工程案例等内容，重点介绍了工程案例库的建设过程。同时也探讨了教师利用网络来优化教学过程、提高教学效率的问题，对土木工程课程的教学改革具有一定的借鉴和参考价值。

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.
