With the deep integration of information technology and modern education, MOOC and other online education resources are developing rapidly. How to integrate offline education with online resources has become an important issue facing the current teaching reform. Soil mechanics is an important core course for civil engineering related majors, which has the characteristics of high theoretical requirements and strong practicality. With the limitation of class hours, it is difficult for students to achieve the requirements of deep understanding and application of this course knowledge only relying on classroom teaching. In view of the new challenges faced by the traditional teaching mode, based on the construction of online resources such as MOOC, the exploration and practice of online and offline mixed teaching reform are carried out. The problems such as the lack of traditional class hours, the low participation of students and the single assessment method are well solved, and good teaching effect is achieved.
