The first time I heard the term MOOC, I was in the passenger seat of a Smart Car driving along the Charles River toward Cambridge, and my colleague Otto Scharmer was asking whether I might be interested in creating one. That was November 2013.

Two and a half years, 75,000 enrolled participants, and two runs of the course later, I thought it might be worthwhile to share some reflections and insights into how we've created - and continue to create - u.lab courses.

My intention here, and what interests me most, is to explore what I don't yet know. Years ago, I studied with a creative writing professor who was fond of the E.M. Forester quote: "How do I know what I think till I see what I wrote?"

Welcome, and let's see what we can learn together.
