I've done these workshops for quite some time.  I talk about the ideas of taking notes and the importance of re-copying and condensing.  As a historian, I use a segment of one of my lectures - literally a paragraph of text -- and deliver it as I would in a class.  The lecture paragraph is shown on a powerpoint slide (they don't need to write it down, although they can).  I use a very obscure topic (Spinning Bees from colonial America) and then I show them a slide of how I might condense those notes (taking out sentence structure, concentrating on main points/new terms).  I then show them another shorter version that we all go over.  I then take away the notes and quiz them and they are always able to respond to the questions.
