Metaverse, which is expected to become a massive communal cyberspace, enables users to walk around, to wander from place to place, and to interact with various virtual objects. Due to these features, metaverse technology has been being widely used in many fields. Recently, COVID-19 is pushing students to the metaverse, which creates an immersive learning experience. One of the advantages of the metaverse-based education/training is to allow learners to study knowledge and skills by themselves. We called this learning method "learner-centered education”. Another advantage is that it provides a collaborative learning experience to learners. Therefore, we can say that metaverse education platform has great potential for active and autonomous learners to collaborate with each other in the learning process.

This Special Issue is soliciting high-quality research papers addressing research achievements, practices, theoretical framework, and challenges for metaverse education platform with mobile devices. Original research articles are welcomed in all aspects including innovative technical developments, theoretical and experimental studies, and practical applications, review articles of the current state of the art, prototype development and evaluation.
