The Ubuntu Educators team is focused on producing open courseware related to Ubuntu and other FOSS applications. The team is currently using Moodle to both develop and publish courses. The courses will be published as CC-BY-SA and be free to take and available for download as well. The goal is to develop materials that are similar to those in the Open Course Library Project or MIT OpenCourseware Project but focused on helping users learn to use Ubuntu and FOSS applications as well as courses that can assist IT professionals support FOSS in their environment.
The Ubuntu Educators will work under the Ubuntu Learning umbrella with two other teams. One of the other teams is focused on the mechanics of actually teaching the courses in-person or using IRC and the other team is concerned with producing materials for courses. If you would like to know more about the Umbrella group you can visit its wiki page.
