Ross, this might not be the best approach, but I've had some overbearing teachers like that before, and its good not to challenge them infront of others. they will always get defensive, and even if you win the argument, its still going to screw you when grades come out.

I would usually ask them to talk to me after class, or set up a meeting durring office hours, and tell them that "I learn better if ... " and put it to them that way.
