Firstly, pre-class self-study. Teachers customize preview sheets and push resource packages for students, allowing them to take what they need and explore independently. If students encounter difficulties during preview, they can self-study micro-lectures, videos, animations, and extended reading materials pushed by teachers at their own pace. Secondly, in-class research and study. Students are placed at the center of the classroom, actively implementing the educational philosophy of “learning as the mainstay and teaching as the guiding line.“ This allows students to achieve genuine improvement in abilities through discussions, exchanges, practical thinking, which is specifically manifested in the “six rings and twelve learning” classroom model.
