      To be a good teacher, you need some of the talents of a good actor: you must be able to

hold attention and interest of your students; you must be a clear speaker, with a good, strong,

pleasing voice which is fully under your control; you must be able to act what you are teaching,

in order to make its meaning clear.

     A good teacher doesn't sit still before his class; he stands all the time he is teaching; he walks

about, using his arms, hands and fingers to help him in his explanations, and his face to express

his feelings. Listen to him, and you will hear the loudness, the quality and musical note of his voice

always changing according to what he is talking about.

     The fact that a good teacher has some of the gifts of a good actor doesn't mean he will indeed

be able to act well on the stage, for there are very important differences between the teacher's

work and the actor's. The actor has to speak words he has learnt by heart; he has to repeat exactly

the same words each time he plays a certain part, even his movements and the ways in which he

uses his voice are usually fixed beforehand. What he has to do is to make all these carefully learnt

words seem natural on the stage.

     A good teacher works in quite a different way. His audience takes an active part in his play-they

ask and answer questions, they obey orders, and if they don't understand something, they say so.

The teacher therefore has to meet the needs of his audience. He can't learn his part by heart, because

their brains couldn't keep discipline: they couldn't keep strictly to what another has written.
