For several years, National Park Service scientists, historians, and educators have been working with National Science Foundation-funded High Performance Wireless Research and Education Network (HPWREN) researchers on developing, implementing, and evaluating Live Interactive Virtual Explorations (LIVE) at several sites. The LIVE activities utilize computers with headsets and microphones to link National Park Service sites with an array of audiences. The two case studies in this paper examine the effectiveness of LIVE activities that allow Washington, DC, inner-city youth to explore two hard-to-reach National Park Service sites: Knife River Indian Villages National Historic Site in North Dakota and the Hawaii Volcanoes National Park.
