The document discusses using 3D virtual worlds to capture learning experiences for asynchronous access. It describes how virtual worlds provide low-cost, safe environments for interaction and presence. Synchronous classes can be recorded in 3D within the virtual world vAcademia. These recordings then serve as asynchronous course content, allowing learners to replay, skip parts, or augment the recordings. Current uses include IT and language courses, with plans to improve accessibility and develop new learning scenarios.
