One of the challenging things on the path to becoming a certified trainer/supervisor of chaplains and other spiritual caregivers is that you need to do a lot of "book learning", but few training programs have classes on the things you need to learn. That means you have to do a lot of studying on your own.
For me, the best way to do this learning is to be what one of my old students called "twice taught". That is, in order to learn it for myself what I really need to do is teach it to others. Today, I did that with the theory of groups in our field of Clinical Pastoral Education (CPE).
I used Google Docs to put together my presentation (below). It was mostly a discussion and part of it was very specific to the residency group I was teaching, but it might nonetheless be useful to some. I'm happy to share it!
