The link below is to a systematic review for the application of Extended reality technology (XR) for learning new languages. Some of the benefits that were found include increased engagement, motivation, collaboration, a more comfortable and safe learning environment, decreased anxiety with language learning, vocabulary acquisition and enhanced story retelling. There were also a number of reported challenges and or barriers that ranged from technology issues to difficulty with how to incorporate VR in a way that maximizes the value of the technology. It appears, that with proper planning and studying of how to best implement XR technology into language learning, that there can be many benefits. I do not believe that using XR technology as your sole method of language teaching is the correct approach, but that it can be a powerful tool if used in combination with other proven language learning methods.
