The Fourth-Annual Connexions Conference was held 14-18 February 2012 at Rice University.  A great time was had by all!  Attendance roughly doubled from last year, to 155 on-site and 60 webcast attendees.  Additionally, 56 hardy souls toiled 16-18 February on a range of technical and content sprints.

Highlights included:

• Launch of OpenStax College
• Partnership announcements with Sapling Learning, WebAssign, Consolidated Graphics, and others
• Siyavula's amazing progress (South Africa is printing 2.5 million high school science and math textbooks - one for every student in the country)
• A technical sprint that helped define a componentized architecture for Connexions that will greatly increase its reach and scalability
• A content sprint that input an entire Siyavula Life Sciences textbook into Connexions in two days!

These are exciting times for open education in general and Connexions in particular.  With this kind of momentum, we are planning to hold the Fifth Annual Conference on our moon base (under construction).
