Although I have never used a VR machine before, I believe that it can provide an outside-of-classroom experience where students can interact with others and immerse themselves in new settings. With the new pre-set environments, which the classroom may not be able to achieve, the VR allows rooms for the "impossibles" as it could be created through programs. Through the "impossibles", it may also encourage the students' engagement with the new "taste" of language learning methods, and attract and/or elevate their interests!
From my perspective, learning a language and/or a country's culture through the VR program can benefit in increasing and maintaining the students' interests for a longer period. Compared with the classroom learning environment, the VR programs are more flexible to produce the "impossibles" and allows more possibilities (or even infinite possibilities), in terms of the story plots, settings, characters, etc., to build the users' sense of attentiveness and curiosity to a greater extent. However, very ironically, the drawback of the same principle is that the users may get bored of the "new" elements eventually after constant use. Therefore, having the VR program as a spice of traditional classroom learning may be more effective. In other words, relying on the VR programs solely for language/culture learning may not be able to have the long-lasting desired effects on and reactions of the users. Yet, applying it as a spark in classroom learning could possibly enhance the learners' potentiality in the aspect of language/culture learning.
Personally, I do not have any concerns at the moment yet in regards to the project or the VR equipment itself. I am, more so, eager to explore the unknown through the pre-created space and to discover what I can obtain from it!
