Memory in the brain is very connection based. Spaced repetition is a good technique for strengthening connections, but not for structuring it usefully. I find the best thing is to make as many connections as possible to and amongst the things you want to learn. For vocabulary: find patterns in the spelling of the word, draw the word, use the word in a rhyme, make a joke about the word, etc. Also, connect the words together such that you can traverse a network of them in your head.
