help the user to be more at ease and comfortable. Although virtual worlds are used as an alternative method of communicating and interacting with students and teachers, a sense of isolation can occur such as losing certain body language cues and other more personal aspects that one would achieve if they were face to face. Some virtual worlds also offer an environment where simulation-based activities and games allow users to experiment various phenomenon and learn the underlying physics and principles. An example is Whyville launched in 1999, which targets kids and teenagers, offering them many opportunities to experiment, understand and learn. Topics covered in Whyville vary from physics to nutrition to ecology. Whyville also has a strong entrepreneurial structure based on user created virtual content sold in the internal virtual economy. Some multi-user virtual worlds have become used for educational purposes and are thus called Multi-User Virtual Learning Environments (MUVLEs). Examples have included the use of Second Life for teaching English as a foreign languages (EFL) Many specialist types of MUVLE have particular pedagogies associated with them. For instance, George Siemens, Stephen Downes continue to promote the use of a type of MUVLE Dave Cormier coined called a 'MOOC'. Even though MOOCs were once seen as "next big thing" by universities and online education service providers such as Blackboard Inc, this was in fact what has been called a "stampede." By early 2013, serious questions emerged about whether MOOCs were simply part of a hype cycle and indeed following that hype whether academia was thus "MOOC'd out." Language Language learning is the most widespread type of education in virtual worlds. Tapped In was an Educational MUVE that started in 1997 with funding support through SRI. It incorporated a web interface that allowed teachers to create secure virtual classrooms for their students. Live Helpdesk support was regularly available. Jeff Cooper held weekly support sessions for teachers to create their own K-12 class, resource room(s) and collaborate with others. Unfortunately funding (and Tapped In) disappeared in 2013. Open Source, Jeff now endeavors to have the code updated with speech to text, text to speech and instant translation. If successful the long term goal is to allow all schools worldwide to install their own on their own servers.
