I took some time to dig into all the online flashcard tools on to the Internet, since everywhere you turn there is another one, and the winner of the competition goes to Quizlet.  I welcome you to test out the other contenders: Flashcard Machine, Cobocards, Brainflip, Ediscio and StudyStack (too tired to link them), but Quizlet’s interface and functionality is superior.

All of them have some nice features, but Quizlet is one place where all my desired features came together, making it the flashcard creator to use with your students.  I must confess that some of the primary reasons why I like Quizlet are: a) the interface is clean and simple (reminds me of Facebook or a Google site), b) you can generate printable tests and flashcards c) you can import from a data file, and d) you can select from dictionary definitions or user-generated definitions.  I was able to create a flashcard set in no time and share it with ease.  It has so many advanced features like sharing, embedding, and groups.  You also have a number of ways for reviewing online through basic drill and kill to a variety of games (some are really needing some work though).  Everything you would want for building your students vocabulary is here.
