This is a facilitated model - respond to questions with other questions to lead the participant to their chosen learning goal.
Every facilitator has the power to create learning communities - reality is few do...
Every course is a blended one - but there is no requirement to participate.
Now there is one 'hub' for all members....less communities, less fragmentation more chance of critical mass and momentum.
Nottingham with implied requirement
Nottingham without requirement
Look and feel are very important....
