In view of the new cultivation mode of civil engineering and hydraulic engineering, the soil mechanics course group of Tsinghua University has constructed the teaching system of soil mechanics and advanced soil mechanics based on blended teaching, and designed and produced a variety of teaching plans based on blended teaching and rain classroom in different classroom modes. Emphasis will be placed on blended teaching mode and practice based on MOOC/SPOC and rain classroom. Compared with the traditional teaching method, the blended teaching method increases the time for preview, but greatly reduces the time for reviewing and doing homework after class, so the total learning time will not increase. Because it greatly increases the time of discussion and helps students to understand the key points in depth, the above steps, if strictly followed, can significantly improve the learning effects. The experience gained from blended teaching methods also played a big role in the remote teaching process during the epidemic.
