Qwiki promises to be an exciting alternative to searching via links and instead being greeted with a multimedia presentation on any topic under the sun. You can visit Qwiki here, and watch a brief intro on its features in the video below. I have already found it to be a valuable tool. It's like having an encyclopedia on film ready to go whenever you need background knowledge. Implications for the classroom: giving students more visceral exposure to topics, which can lead to greater retention/transmission to long-term memory (see Willingham's Why Kids Don't Like School for more on how working memory, uh, works).
