Objectives This study aims to shed light on the ethical issues of artificial intelligence and digital technologies that youth face in their daily lives in modern society, focusing on IoT and generative AI, and to examine educational ap-proaches for youth regarding these issues. Methods To achieve this, we investigated the digital ethics issues faced by teenagers through a literature review of domestic and international academic papers, policy reports, and news articles, as well as case studies from ed-ucational settings in Korea and abroad. Based on these findings, we examined student education and policy measures to address teenagers' digital ethics issues. Results The ethical issues related to different types of IoT usage are associated with the various IoT devices used by youth, and since domestic educational cases are insufficient, education needs to focus on issues such as per-sonal information protection, data security, surveillance and privacy infringement through IoT devices. Regarding generative AI, particularly language models, key concerns include AI bias, generation and dissemination of mis-information, and personal information protection issues. It was found that educational materials for youth and teachers are being developed by metropolitan and provincial offices of education in South Korea and overseas non-profit foundations. Conclusions AI and digital ethics education should go beyond mere prohibition and control, focusing on developing students' ability to make proper judgments voluntarily. Education for youth is needed on issues such as copyright of AI-generated content, and misuse and abuse of data.
