The GIGA School Project has accelerated the use of ICT in education. While there are great expectations to be gained from the utilization of learning data, there are also great ethical and legal concerns. As experts in ELSI, we have organized ELSI based on the classification of EdTech into non-AI and AI systems. In this manuscript, we categorize EdTech into (1) digital teaching materials, (2) classroom support and learning support, and (3) learning management and school administration support, and organize the mapping between each basic technology and ELSI.
