## 1 Introduction  
The rapid evolution of technology has begun to transform educational landscapes. Yet, traditional classrooms often struggle to keep pace with modern learning needs, such as personalized instruction, enhanced engagement, and global connectivity [1]. As students faced increasing demands for adaptability and digital literacy in a globalized world, immersive virtual environments emerged as a promising solution to address these gaps [2]. Among the latest advances, the concept of the Metaverse classroom stood out, offering a fully integrated digital space where students could interact in real time through three-dimensional (3D) simulations, personalized learning paths, and collaborative social interactions [3]. The Metaverse refers to an interconnected, virtual shared space that combines elements of physical reality with digital interactions, allowing users to engage through avatars in persistent 3D environments [4]. This concept extends beyond traditional virtual classrooms in education by providing fully immersive, interactive, and collaborative digital spaces that foster engagement and experiential learning [5]. Although virtual and augmented realities (VR/AR) have been applied in education, existing models primarily focus on isolated features such as simulations or gamified content. They often lack a cohesive framework integrating multiple infrastructure layers, personalization, and inclusive learning environments to create a scalable, adaptable virtual classroom [6]. Recognizing these gaps, this perspective envisions a Multi-layered Immersive Learning Environment (Meta-MILE). This comprehensive framework extends existing educational models by integrating cutting-edge Metaverse technologies, AI-driven personalization, gamified learning pathways, and scenario-based assessments. The multi-layered structure ensures that each critical component of a digital classroom--infrastructure, content and interaction, personalization and accessibility, collaboration and social engagement, and assessment and feedback--is addressed to create a holistic, future-ready learning environment. The Meta-MILE model adopts a multi-layered structure to address the multifaceted challenges of virtual education. Each layer targets a specific aspect of virtual learning to ensure stability, inclusivity, and adaptability. By integrating these layers, the Meta-MILE framework bridges the gap between traditional virtual learning environments and the rapidly evolving Metaverse ecosystem, offering adaptive, personalized, and secure learning experiences for diverse student populations. This paper aims to fill that gap with a novel, multi-layered Metaverse classroom design that prioritizes infrastructure stability, interactive content delivery, accessibility, social engagement, effective assessment, and sustainable scalability. Drawing upon constructivist and experiential learning theories, the study examined how a layered approach could meet the technical demands of a virtual classroom and support individualized and collaborative learning. The proposed Metaverse classroom offered a new benchmark for educational environments that adapt to future technological advances by combining foundational infrastructure with personalized content and secure management layers. The novelty of the Meta-MILE model lies in its holistic approach to addressing critical challenges in virtual learning environments. Unlike existing models, which often focus on singular aspects of virtual education, the Meta-MILE integrates a multi-layered architecture to deliver adaptive, personalized, and secure learning experiences across diverse student populations. By incorporating assistive technologies, multilingual features, and gamification elements, the Meta-MILE model ensures that virtual learning environments are inclusive and accessible, regardless of a student's physical or technological limitations [7]. This paper offers practical implications for educators and institutions aiming to integrate immersive learning technologies into their curricula.
