See my reply above. It is worth noting also that there is follow-up after the workshop (emails, group Skype calls, 1-on-1 follow-up sessions, and accountability buddies), and that the workshops are for many an entry-point into the alumni community and a longer-term community of practice (with many participating in the google group; attending our weekly alumni dojo; attending yearly alumni reunions and occasional advanced workshops, etc.).

(Even so, our methodology if not what I would pick if our goal was to help participants memorize rote facts. But for ways of thinking, it seems to work better than anything else we've found. So far.)
