(by Christopher Allen with Elyn Andersson and Shannon Appelcline) Two years ago, the Bainbridge Graduate Institute (www.BGI.edu) faculty gathered to radically reinvent their sustainable business curriculum for the next decade. Our goal was not only to update course content, but also to significantly update how the material was taught. We wished to make our teaching process (our pedagogy) more interactive and also more effective for students graduating into a 21st-century work environment, where people increasingly work in teams-both online and offline.

I was musing as I was preparing for next week's Intensive at BGI that I have 21 students in my class, an uncomfortable size. That's because it lies between a smaller size where good conversations naturally occur, and a larger size where you can take full advantage of different activities that work well for larger groups. I talk about this a bit in my Group Threshold and Dunbar Number posts, where I call the group threshold size of between 10 and 24 people the “Judas Number” nadir, or low point.
