The information on flashcards is neither elaborated on nor embedded in some form of context. Each flashcard stays isolated instead of being connected with the network of theoretical frames, our experiences or our latticework of mental models. This not only makes it much more difficult to learn, but to understand the implications and meaning of information (cf. Birnbaum et al., 2013).
flash cards are great for working with language learning. but are still a form of cramming. it's there a good way to go one step further and think about how you might use that information in a conversation, or a script?
