I love giving my classes book work to do and then pretend that I am engrossed in doing something else and then watch them from the corner of my eye. Then, without warning, I will look over to two students who are talking but only one of them can directly see me and they say to the other one:
"DANGER, DANGER, DANGER!!!! He is looking at us right now so you better try and cover your tracks the best way you can...sorry but you are on your own as I am going to pretend like I was working all along and just hope he is as dumb as we think he is and will not notice that I was indeed talking. And again, I am sorry but if he mentions anything about us not working I am going to quickly throw you under the bus and say that you were the one talking to me but I definitely was not talking to you - GOOD LUCK!"All of this is said non-verbally by a simple glance, the darting of the eyes, a slight flinch, a twitch of an eye brow or any other very, very subtle form of communication. And the really cool thing is that the other student clearly understands what is said and they then scramble to look like they were not turned away talking but rather picking up a piece of paper or some other innocent activitity.
Teenagers are a riot!! If you cannot laugh doing this job, you just have no business being a teacher because this is funny stuff!!!
My fellow teachers, what are some of the non-verbals that you see in your classes?
