The AI4T project, Artificial Intelligence for and by teachers, is a 3 year experimental European, Erasmus+ project which aims to explore and support the use of AI in education. The AI4T measure consists in implementing innovative teacher training methods specifically designed to meet the challenges of AI in education. The project specifically targets teachers in charge of 15 to 17-year-old students with expertise in foreign languages, maths or sciences. At the end of the project, it is expected that teachers become more confident and conscious users of AI-based resources, that can help improving their practice. Project results will also contribute to the implementation of new teaching methods in the classroom and a well-informed use of AI as support for decision-making. A European network will be created to share experiences and best practices.
