Second Life is an online virtual world where users are represented by avatars. Sarah Jones discusses how the University of Texas at Arlington uses Second Life for networking, training, and educational activities. These activities include meetings, simulations, and information sessions on topics like healthcare, military support, and research. Some benefits of Second Life include reduced travel costs, global access, and an engaging 3D shared experience. While it requires an adjustment to the virtual environment, Second Life provides opportunities to participate in activities and develop a sense of presence.
