Charlie, <<Maybe all we need is text for these kind of discussions but here's an interesting link on art with video/audio content that I ran across this morning that I don't think could be replicated with just text. http://www.youtube.com/watch?v=nUDIoN-_Hxs >> I enjoyed the YouTube experience greatly, and was moved by it, and learned something from it, I think. However: in order for me to ask you, "What does the brilliant video/audio experience "mean"?" I have to use words. (I think). In order for you to be my teacher and respond to my request for help, you will use words, although you might try to find an image or an audio or video stream that would help me. "These kinds of discussions" are, I think, pedagogic discussions: we try to learn from our engagements with each other. Hypothesis: we don't use sound and images for this kind of dialog, this kind of teaching/learning, because they are essnetially secondary, supportive, and not central to the work of teaching/learning. I think at this moment, subject to swift change.
