Hi Hiroaki, You are welcome. I can mail you a copy of the
Hands-on/Minds-on paper via the US postal service as I only have
it in hardcopy and gladly so. I have not observed activity at the
Exploratorium to see the details of how toggling the design of an
exhibit brings about different activity around the exhibits,
though what you explain makes a lot of sense to me. I think
though that in the hands-on/minds-on model surprise is seen as
cognitive dissonance by definition (with this realized as
questioning behavior). That is, surprise in this frame always
creates some form of dissonance ( as realized in language use.).
As for the description of transformation from surprise to
dissonance to a change in activity, I can only think that all of
this is mediated in language use, the tool that is both avenue for
observation and through which these changes occur.
Transformation, however, in my view invokes the interaction of two
elements each of which is no longer the same when taken separately
after the interaction. Experience and understanding, are of course
two such elements.
Thank you for your message too.
