Seminar

My seminar was in a cavernous room, with about 35 students; I was happy to have so many; I asked a question and got several responses simultaneously; the answers reverberated through the room so I couldn't hear anything; I got the room quieted, finally, but the same thing happened with the next question; I stood up on my chair and clapped my hands to get people to be quiet; finally, I thought it was fine for everyone to discuss Lorca loudly with people in their area of the room. Wasn't this the best kind of class participation?
