During the teaching process, I required students to independently explore, cooperate with their desk mates, browse through the texts and pictures in the extended reading materials, and choose the type of terracotta warrior they are most interested in for in-depth research, talking about their characteristics. In this process, the interactivity of the online class was fully utilized, and the students' cooperative exploration ability was cultivated. However, unfortunately, I did not require the students to integrate their exploration results with the knowledge learned in computer classes and make them into presentation slides. Then, when reporting to classmates, they could use the slides to display their learning achievements, so that the classmates could share their learning results by both seeing and hearing.
