In a class with 60+ students, the chance that most of them share your confusion on a particular matter is very small. I recommend (for whatever it's worth) that you save questions for email or office hours. YOUR confusion is of no concern to your classmates, and they aren't paying $40,000 a year for you to help yourself to all the class time in the world. And NO ONE is interested in your hypotheticals, so please refrain from sharing them with the class.If you're called on, then of course answer to the best of your ability, if you care to. No one will be terribly impressed if you answer well, and deft handling of Socratic questioning does not make one a gunner. Now, if you answer a question correctly and say to your neighbor, "Do I intimidate you? Good, I was trying to" then you may be a gunner.In my very limited experience, unsolicited participation in the big basic classes does not increase your knowledge of the material. But I reckon in small upperclass seminar classes, lively discussion would be more appropriate.So I implore you, keep your hand down at all times. Answer when called on and save questions for office hours or study groups.
