In this paper, the issues of modeling the real communicative foreign language environment in the conditions of the institutional educational process by means of redundancy of foreign language information are considered. The role and place of this phenomenon in pedagogical science and in educational practice are designated and justified. The specific conditions and specifics of the redundancy application are considered. Thus, the object of the study is a communicative-oriented language–forming process, and the subject is the modeling of redundancy in it by foreign language means. In the paper, the author substantiates the redundancy of information as a permanent property of the modern communicative environment, which determines the importance of modeling information redundancy in modeling real social communication in the educational process. The novelty of the work lies in the consideration of information redundancy as a regulatory idea claiming to be a local private didactic principle in language teaching in the context of institutional education. Thus, the proposed work fills a gap in research on communicative language learning, in which the redundancy of foreign language information is positioned as something taken for granted and certainly positively affects the process of mastering them. As the main conclusion, the author comes to the position that the redundancy of information can claim the role of a particular didactic principle in modern language education because of its conceptuality on the one hand and specific methodological expression on the other.
