Junior high school mainly has teaching ppt with pictures of stars, occasionally videos and occasionally pop music. I still remember that when the teacher was talking about an article by Lu Xun, he talked about Xu Guangping and Lu Xun, as well as Eason Chan's "Because of Love" and a short video about the selected works of Water Margin, which made me better understand and feel the charm of the text.
The high school stage is the formation period of independent personality. I think it is mainly to create a particularly relaxed atmosphere for students in class, encourage them to speak actively, and don't easily deny all kinds of opinions that you may not accept. Instead, it should be developed in a state where a hundred schools of thought contend, so that students can have a relaxed atmosphere.
