FlashDecks is a great easy to use site for educators looking to create or find digital flashcards. These decks can be used on any browser based device and can contain all types of media (i.e. images) and track student usage. It shows how many questions a user gets right or wrong and used spaced repetition to help them learn a topic. A user can also put cards into collections to help keep them organized.
