Brainscape is a learning service that allows users to create flashcards and then control their learning based on how well they can recall the information they are studying. Brainscape is a step above other flashcard services by providing users the ability to add pictures and audio to their flashcards. The audio aspect is definitely an improved feature for ELA and Foreign Language learners. At my school we offer a medical terminology class and I could see it useful there as well. Brainscape also offers a free iPhone app that allows users to download their flashcards too so that they can study on the go.
Brainscape offers users the ability to see different levels of what they have learned and what they don't know at all. This allows students to focus on the areas that they are weakest in. There are also flashcards that are already created that users can find and start studying immediately for a fee. Users can create an account using standard log in information or connect with their Facebook. See the video below for more information.
