MetaWelt: Embodied in Which Body? Simplex Didactics to Live the Web 3.0.

Nowadays, the increasing use of technologies such as cloud computing, the Internet of Things (IoT), and virtual and augmented reality is blurring the line between real and virtual contexts, leading to the concept of an “on-life” reality. Facebook's recent rebranding to Meta underscores the company's commitment to building a metaverse, a decentralized hybrid ecosystem that combines digital and physical elements. As VR technology becomes more mainstream, it is being incorporated into educational platforms, leading to questions about how teaching will adapt to a new virtual environment where the body's role in learning is different. This study aims to demonstrate how the theories of simplexity and simple didactics can serve as a foundational framework for exploring the potential of virtual reality (VR) in the field of education.
