I came across this website doing evaluation research. It is hosted by the Museums, Libraries, and Archives Council in the UK. The tagline is "an improvement framework for museums, libraries, and archives." All the tabs on the site seem relevant to our conversations [how we define learning], [improving performance], [measuring outcomes], and [case studies]. I am posting the direct link to Generic Learning Outcomes, which spatially and verbally identified the benefits people gain from interacting with a museum.
