I agree with Doug's comments below and would also appreciate any information out there. I have become very cynical about the 'educative power of museum exhibitions' The one time I had the opportunity to do a small research project - evaluating whether museum exhibitions on human evolution were educating visitors-I got a rather depressing result from three very different exhibitions-ie no impact on the visitor at all. Since then I really have struggled to find any specific research on whether exhibitions actually educate/effect the way people think about certain subjects. Most of waht I've read/read about is the educative power of the museum in general through museum outreach/classroom based programmes. Do exhibitions themselves actually effect visitors? Kathryn Mathers PS. I have faith that they do but would love some pointers to some evidence. I've studied, it doesn't look like the museum was in control of cognitive learning. The cognitive and affective goals that were written down, or can be inferred from somewhat vague planning documents, are not met, or only to a small degree. The answer to this seems to be to invoke a mysterious 'museum learning' that we don't yet understand. I can send you some studies we've done. I would be interested in any new approaches, methodology, data sets, etc. that people have tried to pin this issue down. Doug
