Why do we put kids in groups of 30 online (beyond the fact that this number represents a class). Why is it called collaborative learning?
I’d say the further you go past the number 3, the less productive learning becomes. In our game, when 3 kids work together and 5 more passively watch, all will recount what happened as though they we’re actively engaged. Ask them to repeat the activity individually, and those who collaborated originally fair no better than passive observers. In fact the passive’s often notice errors the collaborators made and correct them rather than repeat them.
In a document or test, having the benefit of correcting other’s mistakes is called cheating – in a game or virtual world it’s called learning – and learning in 30s would be a really dumb idea.
