The transition of the Russian education system in the context of the Covid-19 pandemic to online platforms marked the emergence of new practices of interpersonal communication in the teacher-student relationship system. The article deals with deviant manifestations in the online space of communications. The analysis is based on the study of semantic deviations constructed by young people in the process of communication in a changing reality. The starting point of deviations is considered as a departure from the approved norms of communication in educational system, which leads to such phenomena as trolling, gaming, etc. The influence of virtualization of education on the rethinking of the norms and practices of communication by young people is considered, and the educational space itself, due to its greater openness, becomes a platform for the implementation of these deviant practices. Analysis of the data obtained during sociological research shows the nature of the differentiation of meanings in the field of online communication of young people, which is reflected in the education system.
