"A virtual world is a computer-based simulated environment navigated and experienced by one or more users. Over the past several years educators have begun exploring virtual worlds as a powerful medium for instruction."
NIU eLearning entered virtual worlds in 2005 after attending a presentation on Second Life at the Games Learning and Society conference at the University of Wisconsin in Madison. Soon afterward NIU built one of the first university campuses in Second Life. We named this virtual campus Glidden.
