This "Postcard" reports how the earthquake on Tuesday, 22 February 2011 in Christchurch, New Zealand, forced a visiting professor to transform his educational model in one week. It was the first week of the academic year 2011 for the University of Canterbury--and the author's first week in New Zealand. As a Visiting Erskine Fellow at the university, one of his goals was to help redesign a final-year course in the Department of Accounting and Information Systems by introducing an integrated case that would run in parallel with a series of theory lectures. The case method relies heavily on class interaction and discussions of the decisions in the case company and the theories that can be applied. On the first day of classes on 22 February this educational model crashed, along with many buildings in Christchurch.
