I think I am slowly understanding how this online course works, and piece by piece I am connecting the puzzle. As I was reading the textbook, interestingly called, "Teaching Naked" by Bowen J.A., I was highlighting some interesting thoughts. As I was doing so, I looked at the highlighter and thought: what will the highlighter be in this digital age? So I quickly looked up Highlighter and came to this http://vimeo.com/26091209 . This is a pretty nifty little tool that could be of great help to students as well as instructors in this digital age.
