One way you could use flash cards to teach a subject is by defining each concept on its own flash card. You start from low-level concepts or primitives as they're called in programming languages and use those to define more high level concepts. It's exactly how you create a program. You define functions using other, more lower-level, functions. The only problem with this approach is that it's tedious to create the cards. It might also be tedious for someone going through the cards. What do you think?
