The document discusses integrating learning management systems like Moodle with 3D virtual environments like Second Life to support online education. It describes challenges with using virtual worlds for education without additional support, like students floundering without clear goals. The Sloodle project aims to address this by integrating Moodle with Second Life through an architecture that allows tools like asynchronous discussion, document sharing, and assessments to enhance the educational experience in the 3D environment. Sloodle provides features within Second Life like a digital drop box and chat to support learning and help students stay on track.
