I prefer DL in most cases. However, for Math, I would want face-to-face. While I love the interaction normally, the DL classes I have been part of had discussion posting requirements. Most of the time, the discussion was fairly free and open. In one class, posting was like pulling teeth, but post I did.
Grad students, which make up the majority of participants in my classes, seem to interact more freely, but also more carefully, online than in the classroom. The discussion also seems more balanced online. No discussion hogs, lol.
Have fun, L!
