The purpose of this article is to define the functions of the teacher as the organizer of chat communication, which has become one of the foundations of Internet communication. The leading method for the study of this problem is the method of situational modeling, which allows considering chat-communication as a process of new social interaction, requiring the leading role of the teacher-organizer, ensuring the maximum involvement of all participants-communicators in this process in order to assimilate new knowledge by the perceiver (learners). This article presents new methodological methods of teacher's work within the framework of chat-communication, defines the important functions of a teacher, who communicates knowledge in the changed socio-cultural environment. The presented methodological material is designed to help teachers of higher education to use chat-communication as a new channel of knowledge transfer from a teacher to a student to adapt to the new communicative realities, to give awareness of the continuity of the educational process, even in a situation of significant changes in conditions of its implementation.
