This document discusses how massive multi-user virtual environments (MMUVEs) like Second Life can enhance traditional teaching practices through virtual role play. It notes that MMUVEs allow for more social interaction, communication, and immersive experiences than traditional computer-based learning. Specifically, the document proposes using Second Life to create a virtual food factory for role playing work scenarios to improve training for new professionals. The conclusion argues that MMUVEs have not fully utilized student interaction potential and that virtual role play could be a powerful constructivist tool for independent learning.
