The document summarizes the use of an online "Design Space" during the 2012 LMR principals conference to promote online learning. The Design Space was used to: 1) Provide access to workshop resources and allow interaction between presenters and participants; 2) Embed hands-on online activities into workshops; and 3) Engage principals before, during, and after the conference through blogs, announcements, and feedback. The goal was to demonstrate how online spaces can effectively support learning communities.
