If you can spare 56 minutes, you might be interested to watch a video of my presentation on Sounds Good at a Lancaster University staff development event on 15 May 2009. Here's the link: http://www.lancs.ac.uk/celt/celtweb/02rotheram. Thanks to Lancaster University for recording the session and agreeing to a link from here.
I think most of the session is coherent but it includes a passage where I take people through a simulation of a book review exercise and receiving audio feedback. This bit is likely to be more understandable if you also study the book review exercise and then listen to the audio feedback. The materials for this are in the Downloads section of the Sounds Good website, at: http://sites.google.com/site/soundsgooduk/downloads.
