First, students are not interested. I have no interest in the course, so that in any case, there are people playing tricks below.
Why aren't you interested? First of all, there is a distance between the curriculum and reality, and students simply don't need it or it is difficult to use it. Then, in the students' view, learning this course is useless and a waste of time. Secondly, the impetuous social environment has created students' unwillingness to work hard and retreat, and educators have no ability to guide students. So what if students can't learn and can't attend classes? Nature is to do your own thing. Besides, students nowadays are attracted by some interesting things. There are too many interesting things on the mobile phone. Who can study hard from beginning to end? Finally, when students have something they want to do, they decide to give up this course.
Second, the teacher's personal problems. I don't speak well, I have an accent, and my personal conduct is not good.
If the teacher is beautiful, or the lecture is really good, I believe the classroom discipline will not be so bad that it is unbearable. Teachers are advised to improve their self-cultivation.
