Hence you need different phrases/analogies to use to mean one thing as one person might understand a concet presented one way but another might not eg using the bicycle and brake analogy I used earlier, if you have never cycled, the person won't know what I am talking about. A wide casting arc won't be understood by beginners, most will understand windshield wiper or rainbow shape to describe the action.One of the things you quickly learn as a teacher is that what you are saying in your head may make a great deal of sense . . . but the blank expression on the faces of a goodly proportion of a class of 10 year olds quickly suggests that the vocabulary being used isn't projecting the message.
It's the same with analogies. very few people paint ceilings with brushes, mostly preferring the roller and increasingly fewer people had experience of flicking ink soaked blotting paper off rulers during their school days.
Probably the worse crime is 'Instructor Speak' - the, "I have no foundation in scientific knowledge but I'll try to impress you with quasi-scientific words and phrases which actually mean less than nothing in practical terms."
