Spaaze is free (at this point)--cork board that can be used as a display board--video, mp3, digial images and more. Might work well for a project summary (group or individual).
VoiceThread is a collaborative tool that allows collaboration online. Responses may take the form of video, audio, doodle (drawing) or typing) and also phone (scheduled call which will record). Many ways to accommodate learners. Highly recommend. Free, but I upgraded to Pro version.
Great cautionary article on colleges 'googling' students. Should be read by every middle and high school student (and their teachers and parents as well)!
