Exploring the Promise of Digital Twins in Education Beyond Tailored Learning

The incorporation of digital technology and AI into education traces back to the 1960s with the advent of intelligent tutoring systems that were designed to cater to individual learners’ requirements and styles, providing tailored instruction. The journey of large language models, which emerged alongside Natural Language Processing (NLP), began in the mid-20th century. At first, these language models primarily relied on statistical techniques to assess how likely a specific word or phrase was to appear within a given linguistic framework.

Among these early developments was PLATO, an intelligent tutoring system created at the University of Illinois at Urbana-Champaign. This was the first computer-based system where students could interact with educational content through graphical user interfaces, with AI adapting the material to meet their specific needs. Another pioneering effort in utilizing AI for educational purposes was a system that auto-graded programming courses. As personal computers came to the forefront, the evolution of intelligent tutoring systems gained momentum throughout the 1970s, exemplified by TICCIT.

With the rise of the internet, intelligent tutoring systems underwent a substantial transformation, advancing to offer adaptive, smart, and personalized educational services powered by machine learning algorithms. However, their capabilities still remained largely focused on providing individualized learning and instruction. The emergence of Web2 and its focus on social interaction and collaboration marked a significant turning point for the development of these systems.

The introduction of Transformer architecture in deep learning during 2017 heralded a new epoch for intelligent software. Following this, groundbreaking models such as GPT (generative pre-trained transformers) began to emerge, culminating in the launch of ChatGPT in November 2022.

Digital twin technology is beginning to integrate into education

Initially adopted in the fields of aerospace and manufacturing for purposes like design enhancement and predictive maintenance, digital twin technology is now extending its reach into the educational sector. The technology, developed by Antix is introducing educators and students alike to the concept of hyper-realistic digital avatars. Antix employs cutting-edge technologies, including AVAgen—a proprietary tool for the seamless creation and management of digital identities across various metaverses. By harnessing state-of-the-art machine learning and natural language processing, this technology allows for hyper-realistic interactions, enabling users to engage meaningfully with digital environments. Additionally, Antix incorporates blockchain solutions to guarantee the uniqueness and security of each digital avatar, facilitating personalized experiences that evolve in step with users.

Digital twins are capable of offering customized reminders about time management, providing immediate feedback on academic performance, presenting recommended reading lists, and sending alerts for lectures and assessments. By integrating gamified elements, they can enhance motivation and engagement in the learning process. The capabilities of AI-driven digital twins are expansive—they can take over mundane tasks, deliver presentations across various locations simultaneously, and respond to common queries. This technology not only alleviates the pressures on overworked teachers but also enriches the educational experience for students. The AI component of the digital twin can engage individually with each learner, achieving a blend of mass outreach and personalized attention, making it especially advantageous for large-scale online courses.

But the benefits don't stop at personalized interactions. Educators can craft their own digital twins to replicate their teaching styles and tone. These digital manifestations can be employed in classrooms, corporate training sessions, or online platforms, thereby ensuring their expertise remains accessible around the clock.

Using cutting-edge facial motion capture and AI-driven text-to-speech technology, a digital twin can engage with students in a friendly and captivating manner, providing consistent teaching even in the absence of the physical educator. Furthermore, digital twins can monitor academic progress, observe student interactions, and adapt lesson plans in real-time. If a learner encounters difficulties with a particular subject, the AI assistant can dynamically identify this and offer additional resources or exercises tailored to their needs.

Finally, educators can design interactive and immersive lessons through a blend of text, visuals, audio, and video by leveraging a multimodal learning approach together with digital twin technology. This synergistic learning style has proven effective in enhancing comprehension and retention.

Digital twins are poised to help alleviate the escalating teacher shortage

Recent findings from the Economic Policy Institute reveal that the reality of the teacher shortage is far more severe than previously understood, particularly when accounting for factors such as teacher quality, training, and experience. The repercussions of this shortage extend beyond teachers, negatively impacting students and the educational system as a whole. A lack of qualified educators and assistants weakens the efficacy of current teachers and endangers students' overall learning capacity, while high turnover rates drain resources that could be utilized more effectively.

Digital twins stand to revolutionize education by automating standard tasks, ensuring that teaching remains scalable and of high quality. Their around-the-clock availability could be particularly beneficial for students in different time zones or those requiring extra assistance. With real-time adaptability and authentic expressions, digital twins could capture students' interest far more effectively compared to static resources like pre-recorded lectures or traditional slides and modify their instructional strategies to meet diverse learning needs.
