Chatbot in education: trends, personalisation, and techniques
摘要
Chatbots, as rapidly advancing AI technologies, have become increasingly integrated into human interactions, acting as valuable companions. This study examines the role of chatbots in education. We conducted a thorough literature review on published and stored articles in major databases, including the IEEE Xplore and the ACM Digital Library. Following PRISMA criteria, we analysed research published between 2018 and 2024. Our extensive search identified 720 relevant articles, which were then filtered according to established inclusion and exclusion criteria, resulting in 116 papers that met our quality assessment standards. The study aims to provide insights into three key areas: (1) the current state of chatbots in the education sector; (2) the personalisation of chatbots to enhance teaching and learning experiences; and (3) various techniques for chatbot development. The findings indicate that chatbots are becoming essential tools for students and can even augment the role of human educators. We also addressed the benefits and challenges associated with chatbot applications in education. This paper serves as a valuable resource for academics, developers, and researchers interested in chatbot technology in the educational context.
