Using open-ended virtual spaces can be challenging and time consuming for teachers. Fortunately, there are many resources in-world and on the web with general guidelines and specific tools to help teachers be more productive. Most of the groups that host these resources recruit professional members with experience in simulation and game-based learning and invite educational institutions to participate in their organizations. Some of these resources provide a list of best practices for teaching and learning in Second Life (SL) and help sponsor conferences. In this article, the author presents and discusses some of these instructional resources. He states that instructional activities in SL that effectively apply constructivist content and social interactions may result in more robust learning environments that create opportunities for engaging learners. In fact, as a result of this level of engagement, students may potentially experience deeper learning and demonstrate positive behavioral changes in SL than from simply viewing media or communicating through email, text-based chat rooms, or even attending traditional classrooms. Reflective asynchronous interaction, role-playing of social context, and the opportunity to explore new persona may prove to be powerful tools for engaging learners in SL. (Contains 3 figures.)
