The Adobe Atmosphere virtual environments that were the central part of my PhD thesis, but which I never directly published on (apart from a preliminary teaser in VSMM2003 in Montreal+VR in the Schools) is now  – in nearly full experimental glory or honesty  – available online or (soon) in printed journal form in the journal Virtual Reality (Springer website).

abstract: This case study evaluated the effect on cultural understanding of three different interaction modes, each teamed with a specific slice of the digitally reconstructed environment. The three interaction modes were derived from an initial descriptive theory of cultural learning as instruction, observation and action. A major aim was to ascertain whether task performance was similar to the development of understanding of the cultural context reached by participation in the virtual environment. A hypothesis was that if task performance is equivalent to understanding and engagement, we might be able to evaluate the success of virtual heritage environments (through engagement and education), without having to annoy the user with post-experience questionnaires. However, results suggest interaction in virtual heritage environments is so contextually embedded; subjective post-test questionnaires can still be more reliable than evaluating task performance.
