I don't mean those that raise thier voices when necessary to be heard, or on occasions when real displaesure at children's behaviour requires demonstarting.
I mean those that use it as an almost constant method of communication in the classroom, and to give all instructions and corrections, and with an undertone of irrattion and displasure.
I'm sure you know the type.
There are a few of these in my DS's school and it makes me very sad to think of them in this envoronment all day.
And I say this as a strict mother who is known to shout not irregulary herself, but who would hate it to be the ethos and way of communicating in my home.
