Donald Clark has a nice synopsis, in his usual brusque style (!), on knowledge retention as part of learning. He kicks off with the classic graph showing how rapidly retention drops off after first exposure, and then goes through a (mixed) variety of strategies to offset this loss. If students haven’t come across this then they need to be aware of it. And it goes without saying that teachers/lecturers should be building this style of knowledge “training” and re-exposure in to their schedules.
