The view of a classroom as being a conduit where the teacher transmits knowledge from their brain into the students is entirely outdated. That's not how learning works.
To learn, you have to process information, build understanding. One way that has been shown to work quite well at this is to make students explain to each other and challenge each other.
You may have heard the phrase "I didn't really learn this until I had to teach it", which is another reflection of the same thing; the act of explaining to other people improves your understanding.
Not to mention that it also improves your skills at things like making a coherent argument and working with other people, which are quite useful skills to have in life.
If this doesn't work for you, you don't need the teacher either. After all, what can they tell you that you can't just read in the textbook?
