# Application of the Extended Reality Technology for Teaching New Languages: A Systematic Review
## 4 Discussion
While there are several benefits with using XR technologies, prior works reported technical, cultural, and time-related issues when using these technologies. [PERSON] [26] noted that virtual computer games appeared to be effective and efficient with a specific group and they may not work well with other demographics due to cultural differences. [PERSON] and [PERSON] [30] made a similar observation during their study on the effect of AR technology to enhance learner's learning performance, strengthening the learning system, and understanding the education material. They noted cultural limitations with using AR technology to improve students' learning process. These studies highlight that XR technology can help overcome the challenges associated with teaching a new language. Based on the empirical evidence on the use of XR technology for teaching language, it can be argued that XR technology is capable of aiding language teachers in delivering and supporting students with learning new contents. Recent studies outlined the use of new technologies for teaching school children and the technical issues encountered while using these technologies. A study by [PERSON] [39] explains that children who used and experienced augmented storybooks were much better at retelling stories and answering the questions. They reported technical obstacles to using AR educational game systems for learning and teaching purposes. The technical issues encountered include slow system response, failures of tablet devices and breakdowns of software. [PERSON] et al. [34] found that applying AR educational games for learning language can improve knowledge and help complete certain tasks faster and more easily, but the technical issues can limit the students' ability to complete the tasks faster. Theyalso found that young students had difficulty with using the computer mouse and speech recognition. To overcome these technical problems and system delays, every school should have experienced technicians to solve any technical problems that may be faced by the students or teachers. [PERSON] [33] points out that there is still limited research on teaching language vocabulary through XR technology. Thus, it is important to create awareness among students and teachers that the use of the new XR technology helps improve students' language vocabulary and keeps students engaged in the learning process. XR technologies such as VR and MR will not only help with vocabulary acquisition but also support the degree of awareness, progress, and achievement. For example, students using the VR game House of Languages had higher language vocabulary acquisition and better achievements in vocabulary learning than ever before. This shows that XR technology presents opportunities for Arabic language teachers to improve their teaching delivery and students' learning experience. On the other hand, there are still many technological obstacles with employing XR technology for learning and teaching purposes. To gain an in-depth understanding of the technological obstacles, more studies on using XR technology for teaching languages need to be conducted. This will help schools and teachers to (a) understand the key issues concerning the use of XR technology and (b) develop appropriate strategies for the effective use of XR technology in an Australian educational context. XR technology increases learners' fluency, achievement, and engagement. Some studies in this systematic review suggest that XR technology and virtual environments can increase learners' fluency and engagement in learning a new language. As a result, students are notably becoming very interested and engaged in learning a new language after having a virtual classroom environment [25, 27, 32]. However, it can be seen that many challenges such as misunderstandings and delayed responses can affect language learning progress, such as working with disabled students that would make the teaching process more challenging and slower.
