I agree that stress is something that has to be managed in the classsroom. Especially in assessment heavy classes students can get stressed easily. I think that keeping a level head is such an important piece to helping the students maintain self control. I attempt to show the students with my body language that i am calm even in a stressfull situation. I like to act "chill" and then discuss with them later that i was actually a little stressed, but didn't want it to get to me, or let it affect their learning by messing with my teaching....
