Day Four, the final day, of AIED 2011 Conference. Despite the ash cloud, and the earthquake which I am certain made it difficult to put on a conference, the organizers did an outstanding job. I had a wonderful time at AIED 2011, saw a number of interesting and exciting works, and got to meet a number researchers in the field. I am really glad I was able to participate in this conference this year and the long travel was worth every minute, not only was the conference interesting, fun and helpful, New Zealand was magnificent.
