The increased involvement that AI plays in people’s lives highlights the demand for greater public knowledge of AI systems. Lifelong learning environments are especially crucial for building AI literacy as they possess the ability to reach a larger audience and create opportunities for everyone to learn. This ongoing project aims at exploring the perception and understanding of AI by different members of the public (i.e., children, educators and parents). In addition, it aims at promoting AI literacy among different groups of the public (e.g., educators, adults, elderly and children) through an open course and identifying the best practices for developing appropriate training activities. Initial results indicate that after attending a short course on AI, participants were able to understand and recognize what AI is, appreciate its positive and negative aspects, and most importantly, acknowledge the need for educating children and adults about AI. Finally, the results highlight that educating the general public about AI is a complex task that must be informed by further research.
