Education and training is closer to theatre than any other medium, as it is largely delivered ‘live’ and not recorded. It is ‘staged’ and mostly not interrupted. We do, after all, call them lecture 'theatres'.
We know that the mind struggles with long presentations and that most of it will be forgotten, and that cognitive overload or inattention will prevent the acquisition of knowledge delivered in this fashion. The learner is cheated out of pausing or rewinding if a point is missed, or simply to rethink and reinforce the learning. So why is such a stupid model so prevalent?
Millions delivered, few recorded
Every day vast numbers of lectures and talks are given and only a very few recorded. Imagine a novelist, journalist or filmmaker who only delivered his/her work once, live, and refused to have it recorded and distributed. Education plays this 'once only' game on an unimaginable scale. It’s obvious that this is true, less obvious as to why it happens. Why is it so rarely recorded?
Why can't we see it twice or more?
Why doesn’t the learner have the simple ability to replay the talk/lecture/teaching experience? It’s not ‘intellectual copyright’, as the majority of these lectures/talks get culled from other sources and few have any resale value. It’s not because it’s difficult or expensive. Recording as audio or video is dirt cheap. It’s not because it’s against the rules. It's simply not done. The whole system is moulded to the needs of the teacher, not the learner.
This leaves only institutional sloth or fear. Is education simply stuck in a world where technology doesn’t matter? As there's no real sense in which one fails, does the system just trundle on? Can it only think in terms of theatre?
Or do they fear the fact that they may be found out? That it's all an act.
