A colleague using Internet in a secondary school course in Florida reports that in one semester's course he had 500 messages on a particular list, no fewer than 132 of them from a single student who never spoke up once in class. There's something pathological about such an extreme case, but it's a good reminder that people find their voices in different ways, and this can be one way to create a space in which the balance shifts and different voices are more clearly heard than in the liveware classroom.
