Retrieval

Research shows a good way to learn is through retrieval: testing knowledge with flashcards, instead of simply reviewing a text over and over again. 

While it might not feel like it, imposing the difficult task of trying to remember a fact or concept, without confidence that you know it, is actually more effective than re-reading something you think you already know.

Having ‘knowledge fluency’ is useful, as it means you can recognise something presented to you, but it doesn’t propagate.  Being able to retrieve that information cold, means you’re more likely to be able to generate new thoughts and ideas.
