Artificial intelligence (AI) is changing the face of education. AI tools such as ChatGPT, Gemini, intelligent tutoring systems, automated evaluation systems and learning analytics are already impacting the global learning and teaching landscape. These changes present new possibilities to improve the quality and accessibility of education, but also raise a number of questions about the nature and role of teachers. Traditionally, teachers are seen as purveyors of knowledge, mentors, facilitators and role models. But these are changing dramatically in the age of AI.
