Scott Wilson's powerpoint slides contrasted the controlled, closed environment of a LMS with an free, open Personal Learning Environment (PLE).
I like to add another environment into the mix - a virtual rehearsal/practice space.
While PLE enables learners to model learning to more realistic environment, or even participate in real environment during learning, there are situations whereby such participation is very expensive (pivots need to learn how to land an aeroplane when there is crippled landing gear ), dangerous or morally unacceptable.
At a more personal level, at critical events, we rehearse. (Think wedding rehearsal...) We also do that for speeches, presentation, etc.
For complex political environment, students can learn through political role play simulation.
