I'm glad to hear it works for you; it does sound like it should, but confirmation is nice :-)

There's been all sorts of talk about different kinds of anticipatory set in my classes, but it generally boils down to that: you really just need to get the students into the right frame of mind, and then you won't have discipline problems.

Classroom management instead of discipline; which also jives with the heavily-emphasized "Do Not Punish Students" message (also something I agree with).
