Virtual Reality as a way to study English?

An article from a newspaper today says that Korean students learn English through Virtual Reality. I'm not sure if this would be a good way to learn English or any other language. It could also end up as another means of studying a language not necessarily effective. Korea, a country that craves too much for "learning" English, seems to be developing more "creative" teachniques in learning the said language.

In the article this was the situation: While buying a subway ticket in Boston, a Korean elementary school student asks an agent what direction she should take. Following the instruction, the student takes the train at the platform. The early teen checks a tour guide on the move to learn when she has to get off. She leaves at the right stop near the hotel where she is supposed to stay.

This does not take place in the United States but in a class at a primary school in Daejeon, about 100 kilometers south of Seoul. The latest technology creates the above-mentioned virtual reality.

``Virtual reality is a real-time interactive program designed to teach English more efficiently at schools,’’ said Electronics and Telecommunications Research Institute (ETRI) official Lee Jun-seok who developed it over the past few years.

The idea might be noble but I am doubtful if it would be successful. Based on the article I could already pinpoint a lot of discrepancies as to its applicability and effectiviness.
