This document discusses SLOODLE, an open source project that integrates learning management features from Moodle with interactive 3D environments like Second Life. SLOODLE allows activities like lectures, assignments and quizzes to span both Moodle and virtual worlds. The author explains how SLOODLE works and provides examples of how teachers could use it to engage students accustomed to gaming and virtual worlds in new styles of online education. Specific SLOODLE tools are described that link the two platforms, like allowing students to submit assignments or take quizzes within Second Life.
