For the epidemic situation, many schools in our country have taken the way of linkage with the Internet and started the online teaching. The way that the teachers have webcast, or through the way of learning app, has taught the students. I think this is also the innovation of teaching methods, so that the progress of students' courses has not fallen, but this method also has disadvantages, leading to the decrease of students' enthusiasm for learning, but it is good The harm outweighs the harm. I'm still positive about the online teaching during the epidemic.
