The increasing presence of robotics, automated systems, and AI in everyday life is carrying important ethical and social implications for both those who design and develop them as well as for the users. Addressing these complex issues requires active collaboration between multiple stakeholders, including children. Nonetheless, even if emergent technologies are becoming increasingly present in education, most technology-mediated educational projects for children tend to focus on the development of technical skills, leaving little room for critical reflection. This tendency runs the risk of missing opportunities to truly empower children as critical users, (future) responsible designers and skilled stakeholders in the dialogue around ethical concerns on technology. Starting from this perspective, the workshop aims at tracing research lines and opening questions around strategies, methods, tools, and perspectives to support children in developing an ethical and critical sensitivity in the use, design, and development of emergent technologies.
