Save My Whiteboard 2.0

"Save My Whiteboard works in concert with your digital camera to save the notes you put up on your whiteboard in a format that Calvin or your other students can view and print on their computers.
I find that students having difficulty understanding the lecture are faced with a perplexing decision. They can either take notes like crazy, trying to write down everything the professor says, and hope to decipher them sometime after class, or they can put down their pencils and concentrate completely on the professors explanations, perhaps asking a few questions along the way and hopefully understand what transpired.
As a professor, I would prefer them to take the second choice, but this leaves them without any notes, which means it is difficult for them to reconstruct the material later. I find it difficult to make notes ahead of class to pass out, and in fact often I dont make any notes at all before the lecture, which leaves my students in a pickle after I erase the whiteboard.
I decided to try and solve this problem. "Save My Whiteboard" along with my new Olympus digital camera is my solution. I have used this for a couple of weeks already, and received some good comments from the students. This quarter is the first one I intend to make a complete collection of my notes available to students on the web using Save My Whiteboard."
