Abstract: Based on the theory of learning community and Bloom’s educational objectives classification, a teaching strategy of “problem oriented” and “interactive teaching” is adopted to promote each other. A “five guidance and one promotion” SPOC flipped classroom teaching model is constructed in three stages: pre class, in class, and post class, and applied to the teaching practice of soil mechanics courses. Pre class guidance promotes active learning among learners and stimulates their interest. In class, “guiding research, understanding, and thinking” takes problem-solving as the starting point, and through teacher-student interaction and student-student interaction, learners can achieve internalization of knowledge transfer. After class guidance focuses on problem expansion, and through reflection and consolidation, it promotes the cultivation of higher-order thinking in learners.
