This study evaluated the multi-user virtual environment (MUVE) known as Second Life, integrated with Moodle and SLOODLE technologies, as an exploratory course delivery platform and for its ability to enable teachers to meet elements of NETS.T. Graduate student participants (N = 17) interacted, constructed simulated schools, and attended classes in the MUVE. The researcher used pre- and posttest measures of self-efficacy and learning efficiency to understand the effects of the MUVE on participants and their rate of learning to make educational use of the environment. Findings imply that the technologies have potential as a distance-learning platform and as a tool to meet elements of NETS.T. Preparing teachers to use the MUVE for these purposes is likely to require a significant amount of scaffolding. (Contains 5 tables and 2 figures.)
