This semester I have been bringing a simple digital camera into class, where I have a long whiteboard that I use heavily. During our class discussions I regularly jot down student responses to questions, their questions, outlines of concepts etc. on the whiteboard. I try not to erase too much so that by the end of the class I have just about everything we registered. Just before I leave class I take pictures along the length of the board. Then using a neat program called Microsoft ICE (a free piece of software) I put the string of pictures together (in less than a minute) to have a full panoramic shot of the board. I then post these in Blackboard in our class, for our future reference.
Today I also finally found a nice online image mapping software. So now I can create an image map from the panoramic shot, and each note on the board becomes a hot-spot link to a web resource that fleshes out the idea noted on the board! I can't wait to see how this might be useful as we go along! I will post the link to a sample map as soon as I get it uploaded!
