I'm a student at the University of Toronto Museum Studies Program, and I was surprised when our museum education class concentrated on informal education. We were taught by two museum professionals from Toronto. It seems that a lot of information about informal ed. has to be found outside of museums literature. We spent a lot of time trying to develop a model of the visitor's experience. We couldn't agree and couldn't find any models that suited everyone's conception of what processes visitors go through within an exhibit. So as a long winded answer, yes people are thinking about informal education and museums, but the answers aren't clear. Carol Martin
