I teach math in the first year of the university. When I started, One very useful recomendation was:
> Whater you write in the blackboard, they will copy in their paper notebook and may read and learn some day later.
> Whaterver you only say, goes away with the wind.
So I try to write down in the blackboard everithing I say.
So slides for a classroom shoud have more text than what I usually expect.
