The Inquirer.net has an article on Education Technology funding that mentions Second Life.
Quoting: “A report by Sloan Consortium in 2013 shows that 74% of Chief Academic Officers in US considered the learning outcomes in online education as the same or superior to those in face-to-face instruction.”
And: “TOPICA is among the first organizations to apply latest technologies like Google Glass, Mobile, IPTV, and 3D Second Life into online teaching. In 2008, they integrated 3D technology called Second Life into their online degree courses like microeconomics, business law, math, accounting, algorithms etc. where students can walk around and interact inside that 3D virtual environment. Their 3D technology did not just create a new visual environment for teaching; it also created strong motivation for students to learn.”
