When I did it on my basic course, it was practically death by powerpoint! They just go over different scenarios that you might experience during a game (like a kid telling you their parent beats them), then how you would deal with it. We then used cards to say how severe we though something was, ranging from a few scratches on the face, to constant bruising (you get the idea).
Finally, we were given a massive book with all of the information that we had just been shown on the powerpoint and a lovely certificate to say we had completed it!
