Various studies on artificial intelligence ethics are being actively conducted, but considerations on terms and concepts of information ethics, computer ethics, Internet ethics, cyber ethics, and robot ethics are relatively insufficient. In this paper, we reviewed the concept of an information ethics framework that encompasses the ethics mentioned based on the platforms. Computer ethics and Internet ethics, recognized as the same concept, are the user's norms for Internet-connected software, cyber ethics are the norms between users in virtual space, and robot ethics are the norms of humans and robots in physical space. Additionally, teachers' perceptions of conceptual differences in related ethical terms were investigated based on the information ethics framework, and teacher training needs were investigated. In addition, teachers' perception of the importance of eight ethical standards (addiction, prevention, security, privacy, net ticket, public good, happiness, data fairness, human dignity, transparency, and safety) was investigated for cases based on human computer interaction in three information technology environments (communication platform, softbot, and robot).
