Creating Effective Flashcards: From Indexing Ten Thousand Cards
I indexed ten thousand flashcards before I understood what made a card effective. Here are the principles that separate cards that stick from cards that fade. I have created over ten thousand flashcards across six years of study and teaching, and most of my early cards were terrible. They were too long, too complex, and too ambiguous. They tested multiple things at once and had answers that were open to interpretation. It took me years of trial and error, plus a deep dive into the cognitive science of retrieval practice, to develop a system for creating flashcards that actually work. Here is. One Card, One Fact The most important rule, and the one I violated most often, is that a flashcard should test exactly one fact. A card that asks for the definition, symptoms, and treatment of a disease in one answer is not a flashcard. It is a mini-essay disguised as one. The user has to recall three separate things to get the card right, and if they recall two but not the third, they do not know whether to mark the card as known or unknown. The card becomes a source of ambiguity rather than a clean test of recall. I now split compound cards ruthlessly. More guides are on the Quiz Hub Blog.
