Abstract: Metaverse, as an emerging, interactive and immersive 3D virtual space technology of Web 3.0, is expected to lead to a profound transformation of the educational process. Its ability to combine digital presence, direct interaction and experiential learning offers new perspectives for active student participation and personalized learning in virtual environments. Within this context, the present study focuses on examining the integration of Metaverse into education, exploring its potential and advantages, as well as the issues and challenges that may arise from its use. To support the research process, a mixed methodology was used, which included a literature review, a qualitative study, and a quantitative study. In addition, pilot virtual worlds were created on the Spatial.io platform, using the ADDIE method, offering teachers the opportunity to test and gain experience. The results show that Metaverse contributes substantially to the improvement of learning experience, offering realistic and interactive learning environments, while enhancing social interaction and promoting experiential learning. However, potential risks must be taken into account, such as digital inequality, malicious use of educational data, prevention of cyberbullying, and unnecessary and excessive use of the metaverse by students, such as isolation from the natural environment and obsession with virtual worlds and our digital persona. In conclusion, the empirical research reveals a positive response of Greek teachers to the proposed Metaverse model, predicting improvements in the learning experience and student interest.
