I think a lot of you remember a 2 inch strip of scotch tape across your lips, which is alot more figurative than restrictive action. This teacher went completely around the kids head about 10 times creating layers. Way out of line.
My mind set is this. If discipline is necessary, I will administer it at home. No one on this earth has the right to touch my child in anger or corrective action. Police, teachers, no-one. If there is a problem, call me and I will deal with the scenerio.
This teacher should be fired, if the only way they can deal with a talkative child is to tape their head like a mummy. Teachers are trained to deal with disruptive behaviors in college and the districts publish guidelines. Good quality teachers are aware and skilled at how to deal with these scenerios without resorting to abusive behavior.
