I have four in one and eleven in the other, yay, and so I need to adjust my teaching style accordingly. I've been used to lecturing, which involves, for me, pacing about and shouting to about 100 people. Four people in a room for an hour and a half is much more a chance for careful thinking and group discussion.
And unbelievably, it being Rice, I have a teaching assistant! Sydney Boyd, from whom I expect great PhD work fairly shortly.
Writers block? Can't think of something to say? Try teaching. It always helps.
