Depending on the course and the room, I may use my tablet PC  rather than the whiteboard to present the material and provide examples.  In these cases the notes are later posted below. 

For the past several years I have used Windows Journal with the tablet PC.  Internet Explorer is preferred to view the files, but if you use Mozilla Firefox as a web browser, you may open this Word document which explains how to install an add-on to view .mht files.  If you have access only to Safari, please let me know.  I could try a different format for writing or saving my notes.
