Abstract:Soil Mechanics is the core and main course of Civil Engineering. It has strong specialty, numerous, trivial knowledge points, and high flexibility in application. It has abstract concepts and many hypothetical conditions and idealization theory, which easily make students incomprehensible and difficult to use. Taking the online course of soil mechanics of Hohai University as an example, this paper expounds the significance and difficulties of the "Golden Course" construction of open online course under the construction standard of Higher order property, Innovation and Challenge. This paper lists the specific measures to promote the construction of "Golden Course", for example,reforming the curriculum system, adopting case teaching methods, integrate ideological and political education concepts, and combine with the form of flipped classroom to improve the teaching content, improve the vitality of the course, raise students" ability to solve problems and cultivate students" comprehensive quality.
