Viv and I have put up this little slideshare about Action Storming (or Problem Theatre as David Simoes-Brown christened it.) I wrote a post describing it in a bit more detail here and Viv talks about it here.
Training courses so often promise certainty about what you will learn. I'm much less interested in offering people content in this way. I generally don't like reading instruction books and prefer to learn in a more experiential way. I like processes that support playful exploration, trusting participants to find out the stuff that works for them. I'm very wary of what I call the teacher trance, where groups appear to vest power in the expert and actually stop learning. It's safe, but it's boring.
