As an important form of education in the future, Edu-Metaverse cannot only innovate the existing teaching mode, provide diversified teaching resources and environments, realize intelligent teaching evaluation and certification methods, etc., but also realize the real integration of people's physical world and virtual world. Therefore, how to deepen the concept of metaverse into the field of education and creating an innovative education model has become the challenge of this research. To this end, this paper develops a comprehensive Edu-Metaverse ecosystem architecture which provides an effective implementation reference for the development of the Edu-Metaverse. In addition, the Edu-Metaverse teaching mode is constructed, and the feasibility of the Edu-Metaverse teaching mode and its breakthrough significance to the existing offline and online education are demonstrated through questionnaires. Through the case study of Edu-Metaverse teaching, the implementation scheme and effective ways of Edu-Metaverse are verified. The research shows that Edu-Metaverse can not only broaden and deepen the educational content, but also reduce the educational cost and improve the quality and efficiency of education, but it also has potential risks.
