Abstract
Significant advances in new emerging technologies such as the 5th generation mobile networks (5G), Expand the reality (XR), and Artificial Intelligence (AI) enable extensive three-dimensional (3D) experience and interaction. The vivid 3D virtual dynamic displays and immersive experiences will become new normal in near future. The XR-based virtuality-reality co-existing classroom goes beyond the limitations of Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR). Such technology also enables integration of the digital and physical worlds and further creates a smart classroom featuring co-existed virtuality and reality. In this paper, we show an application of the XR enabling human-environment interaction. Through the theory explanation, practice platform and combination of virtual and reality, using XR we construct a new type of class. We develop the teaching methods using digital enabling, building information model library, and offline XR immersive teaching, and design a mixed teaching method which is virtual and real, and is available in online and offline formats. In our developed system the working scene as it is seen in practice is shown to the students. We consider the steel structure construction technology course in civil engineering and architecture as an example, to help the learners develop their theoretical understanding and practical skills. We also discuss the application and development of the class based on virtual and reality. This work shows the feasibility and significance of learning methods and the reconstruction and transformation of learning spaces empowered by new technologies in the digital era.

Summary
Cone of Learning (see Fig. 1) is proposed by the National Training Laboratories, Maine, USA [1]. In subjects such as traditional medical education which is mainly focused on animal specimens, cadavers, and teaching AIDS, the main issues are insufficient resources and a high risk of patients’ safety [2] Another example is the aircraft design and operation, where without physical observations, it is difficult for the students to correctly gain mastery on the subject only based on conventional multimedia means, such as pictures, animations, and videos [3]. To address the above issue, it is an immediate need to seek technological solutions enabling the simulation of the actual scenes and construct virtuality-reality-coexisting classrooms Such a classroom significantly improves the learners’ experience and meets the surging demand for diversified learning scenarios. The steel structure construction technology course of civil engineering and architecture is used as an example to show how using XR enables restoring the real working scenario and helps learners better understand the concepts and apply their knowledge in practice
