I put up some charts that show how the practitioners in each session group compare along skill/experience lines.
This is not the main cross-session analysis I'm doing, which is more qualitative in nature, but it will help in the overall comparisons.
For example, it's easy to see that Ames Group 2, which was in many ways the least successful of all 8 groups in terms of getting participants to engage with the representation, also had the lowest self-assigned scores in the facilitation measures (slides 2, 3, 4, 5, 6, 7, and 11), although they had a relatively high level of skill/experience with software and hypermedia (slides 1, 9, 10, 11, 12).
One question -- do the (manually added) vertical lines separating the sessions on slides 6-12 help? Or do they clutter up the display?
There are probably better Excel ways to show this, but I'll worry about that later.
