Philosophical facilitation and GM-ing

I tried facilitating a workshop in a demanding seminar on practical philosophy and it was alright but I lost it towards the end, not in the sense that I went crazy, but lost the focus and slipped out of the role. I am pretty confident that the role of managing a game, as DM or GM is similar, and I'm interested in mastering both arts. Now: I think the current method of training teachers is completely inadequate because they don't really instill this skill of taking real charge of an actual group of human beings for a certain period of time... like a facilitator or a GM does - without being authoritarian or 'strict' in an old fashioned boring sense....
