ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.
*****************************************************************************
When I do a summative evaluation on an exhibition I look for two indicators.
1. The exhibition's holding power- measured by sweep rate. I use the Paying
Attention Study (1998, Beverly Serrell) as a baseline to compare the
exhibition's sweep rate against 114 other exhibition sweep rates. The
Paying Attention Study took 114 exhibitions at various museums around the
country and conducted summative evaluations of each exhibition. Although
there is controversy here, I believe that sweep rate is proportional to
interest and therefore motivation to learn. I saw an example of this
earlier this year with an exhibit component that was borderline working.
Making the component work appeared to be intuitive. But when visitors put
the pieces together- then turned the crank, it worked very briefly then
failed. This slight success drove the visitors to try again- and again a
very brief success, then failure. The attracting power and holding power of
this component was incredible. When a child couldn't get it to work, a
parent jumped in with the same degree of success and failure. Soon the
other parent jumped in and then even strangers were offering advice and
exasperatedly waiting for their chance to make it work. The visitors saw
the component as a challenge- the institution saw the exhibit componet as
broken. The holding power of this component (which slowed the overall sweep
rate of the exhibition) indicated an increased interest and motivation to
learn.
2. What messages are the visitors coming away with? This again comes from
the Paying Attention Study, but it is not possible to compare message
outcomes with the other museum's message outcomes. It is up to the
institution to determine if the message is desirable. The institution may
consider the exhibit unsuccessful if the message that was intended is not
the message that the visitor comes away with. But what if the outcome
message is, in fact, more desirable than the designers really planned? Say
for example the designer's intention was to "teach" about how the lungs
work- but, visitors are not learning that concept. However, they are coming
away with an understanding of the importance of caring for and protecting
their lungs- and express an intention to make life changes to protect their
lungs. Is that a successful exhibit?
