Clapping gets message across
I find it is an excellent way to illustrate the concept of criterion referenced assessment. With groups of more experienced teachers it works well for demonstrating the importance of explaining assessment criteria to learners.
Dennis seems to miss the point about employing games in teaching: the games are merely intended to be illustrations of more complex ideas, they are not an end in themselves.
Perhaps he needs to liven up his teaching?
