  Since the end of 2021, the Metaverse has been booming. Many unknown
possibilities are gradually being realized, but many people only determined
that they use Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality
(MR) in the Metaverse. It is even considered that as long as the above
realities (VR, AR, MR) are used, it is equal to the Metaverse. However, this is
not true, for Reality-based display tools are only one of the presentation
methods of the Metaverse. If we cannot return to the three main characteristics
of the Metaverse: "digital avatars," a decentralized "consensus value system,"
and "Immersive experience," the practice and imagination of the Metaverse will
become very narrow. Since 2022, the concept of Metaverse has also been widely
used in classroom teaching to integrate into teaching activities. Therefore, to
prevent teachers and students from understanding the Metaverse not only in the
"Using VR, AR, MR is equivalent to Metaverse" but also pay more attention to
the other two characteristics of the Metaverse: "digital avatars" and a
decentralized "consensus value system."
