LSS has leveraged Drupal to build a few template-based instructional systems: LessonShare and Collaborative Sites. LessonShare is a collaborative lesson-building system for instructors and teaching assistants. Collaborative Sites offers a streamlined course website that provides a wiki-based platform for student-generated content.
I love the innovation behind LessonShare -- create a system that addresses an unmet instructional need (lesson plan building and sharing) -- and I equally love the efficiencies of the Collaborative Sites project. I'm sure it addresses LSS's growing demand for wiki-based course sites.
In an upcoming WisconsinWeek article about Collaborative Sites, Doug Worsham and Sue Weier of LSS answer the question, "How does Collaborative Sites differ from the campus course management system (Learn@UW/D2L)?" Their response:
"We're really not creating an all-encompassing solution meant to support both course administration and student interaction. We're focused on online interaction and collaboration....We're not trying to make the Swiss Army knife, we're making the corkscrew."
I see that Doug has posted an online guide to setting up collaborative sites in Drupal at http://opensig.comets.wisc.edu/?q=collaboration
