That's an interesting way to analyze the situation, Alex. I agree with Leslie that it seems to look at the question from an individualistic perspective, i.e., I need an answer to my question. It doesn't address the potential communal benefits of class participation. For example, something I say may inspire someone else to make a point that wouldn't have occurred to them had I not spoken. Someone might feel more comfortable speaking because I say something so stupid that I've set the bar low for them.

The communal benefit factors might make class participation more rational, and make clamming up during class and asking questions privately the more self-gratifying action. It seems more apt to describe the economic, rational, cost-benefit analysis as symptomatic of the problems we've been talking about in class, namely the need to be certain, the need to quantify, etc.
