ABSTRACT
Some aspects of non-verbal communication, in its broadest sense, can be arranged before the lesson starts. These include the layout of the room, which can influence communication with the class in general or with specific children, and dress cues, which both teacher and children can use as a fixed signal to everybody they encounter of the kind of person they would like to be taken as. These factors have the enormous advantage that you can arrange them with time to reflect and if necessary to consult colleagues: unfortunately their effect is not strong enough to overcome disastrous execution during the lesson itself.
