I ran a session for the Broadband for Seniors volunteer network in May 2012, on Adult Learning principles.
Not wanting to be didactic about it, i tried to draw in the audience perspective whenever possible. Basically, we started with a classic version of 'adult learning principles' and attempted to connect these abstract ideas with people's daily experiences in the kiosks.
This presentation has the audience input on many slides (except one where i was concerned about time.) Overall i found it an amazing session, because of this group participation.
There is a recording of the actual session - i'll see if i can link to it from here.
