This chapter explores the transformative potential of Digital Twin (DT) technology in education, with a particular focus on its application in Science, Technology, Engineering, and Mathematics (STEM) fields. Digital Twins, initially developed for industrial and research applications, are dynamic digital replicas of physical systems, enabling real-time monitoring, predictive maintenance, and operational optimisation. These capabilities provide an unprecedented level of interactivity, allowing learners to engage with complex systems in a way that traditional methods and simulations cannot offer. Digital Twins are shown to enhance operational efficiency, improve decision-making, and provide invaluable hands-on learning experiences. In educational contexts, Digital Twins facilitate immersive and interactive learning by incorporating real-time data from physical entities into digital models, providing students with instant feedback and the ability to simulate real-world scenarios. This chapter outlines the benefits of using Digital Twins, such as fostering deeper understanding, encouraging collaboration, and allowing safe, cost-effective experimentation. Moreover, Digital Twins help bridge the gap between theoretical knowledge and practical application, equipping learners with skills relevant to technology-driven industries. Through an in-depth case study of a miniaturised Connected Autonomous Vehicle (CAV), the chapter demonstrates how Digital Twins can be applied effectively in STEM education. This allows learners to develop skills in areas such as machine learning, sensor fusion, and autonomous vehicle technology. These active learning scenarios promote problem-solving and technical proficiency, preparing students for future challenges in their fields. While implementation challenges, such as high costs and technical complexity, are acknowledged, the chapter argues that the educational benefits far outweigh these obstacles. As Digital Twin technology becomes more accessible, its role in revolutionising education will continue to grow, enhancing student engagement and learning outcomes.
