In general my feedback is that I have learned as much as the students collectively on this entire exercise. This year was in many ways better than last year. The major problem actually came down to a breakdown in communication resulting in a confusion as to when this component of the course was to be delivered. If I do this again next year, I will seriously consider forcing interdisciplinary groupings. This will no doubt cause other problems, but I think this would make some aspects better if the mix of students is right.
