Introduction to the BJET special section on Immersive Virtual Reality in education Recently there has been a proliferation of affordable Immersive Virtual Reality (IVR) apps and hardware that has made the use of IVR in educational settings more accessible to students and teachers. Google Cardboard and other smartphone headsets means that IVR educational experiences can now be integrated into the classroom using free or low-cost learning apps. Commercial Head Mounted Displays (HMDs), Cave Automatic Virtual Environments (CAVEs) and all-in-one untethered IVR headsets such as Oculus Go ™ and Quest ™ provide other opportunities for students to experience IVR environments for the purposes of learning. However, research into the pedagogical application of IVR has not kept pace with technological developments or usage in educational contexts. That means educators and researchers do not have the evidence base they need to determine the "when," "why" and "how" of using IVR for learning and teaching. Accordingly, this special section for the British Journal of Educational Technology on Immersive Virtual Reality in Education (affectionately known as BJET IVRiE to the editorial team) called for analytical and critical research papers that could help provide a broader, deeper and more up-to-date understanding of IVR use in education. The initial call for paper proposals resulted in 46 high calibre abstracts, of which, 17 were invited to submit full papers. All of the invited submissions underwent BJET's rigorous blind peer review process, with over 40 field specialists from around the world agreeing to provide expert reviews. Of the 17 invited submissions, 13 were finally accepted for publication. The editorial team attributed this high acceptance rate to the initial call for abstracts, which allowed only the most robust and well-developed proposals to progress to submission. The high acceptance rate was also in part due to extensive work of the authors and reviewers, which in some cases involved four or five revisions before a paper was accepted. Overview of papers A wide variety of papers are included in the BJET IVRiE special section, focusing on different discipline areas, IVR technologies, levels of education and methods (see Table 1). This variety of papers enabled the special section to indeed address its aim of helping to provide comprehensive insight into the current state-of-the-art and science of IVR in education. Taken together, the papers offer broad insight into the benefits, pedagogies, relationships, methodologies and design issues relating to the use of IVR in education. Two systematic reviews are included in the special section. Wu, Yu, and Gu (2020) report on a meta-analysis investigating the effectiveness of IVR using HMDs on learning performance. Based on 35 recent randomised control and quasi-experimental studies incorporated into their analysis, they conclude that IVR approaches using HMDs are slightly more effective than non-immersive learning approaches. IVR using HMDs were found to have a greater impa...
