It's a good interactive method to constantly challenge yourself into remembering and learning material.
Basically, what you're supposed to do when you're actively reading material. I never really learned how to study until later in life but apparently this is how you're supposed to do it.
I think we don't see it a lot in many classrooms because of economy of scale. When I was in school, we had a professor who did this with his smaller class on computer networks but seems like maybe didn't in his larger classes. He'd ask questions but so many people trying to answer, less time for personal answers (which was fine with me since I was always the slowest person in the room).
