No matter how hard you try to have a dynamic, interactive feeling to a workshop, if you are in a room where the furniture is all facing forward and bolted to the floor, people's assumptions are that they are there to sit still and listen, and not to look at each other and talk.
We have just launched our New Learning workshop, our room is a banked auditorium - very nice, very wired, not too big and very quiet at the moment. Of course, we are at the introduction and context setting part filled with short presentations. And we will get to work hard to change the dynamic once we move past this part to participants' introductions, which I will facilitate next. Needless to say, I was delighted to notice that the chairs do swivel.
