The article considers a speech genre borrowed from American and Western European educational tradition, which is an axiologically oriented text of a student’s comment on the teacher. The article continues the study of evaluative speech genres of educational discourse, considering the problem of speech genre borrowing from an axiological perspective. The aim of this study is a linguistic and axiological analysis of students’ public evaluative utterances commenting on their attitude to teaching. Speech borrowing is one of the least studied problems in linguistics, which determines the relevance of the present study along with the importance of the sphere of education itself for the culture of society as a whole. Based on the communicative and semiotic concept of speech genre, the author identifies and analyzes the value aspects of student evaluation of teaching quality, identifies general and national specific features of English- and Russian-language evaluation texts, identifies and describes factors of conflictogenic evaluative statements of this genre, distinguishing features of functioning of pragmatic category of categorization in Russian- and English-language evaluative texts. The article reveals the absence of clear speech-genre criteria in Russian students’ evaluative comments unlike in English-language practices, which can be explained by the fact of speech genre borrowing and the lack of relevant speech-genre competence in the Russian-language educational discourse. The article considers the linguistic and ecological aspect of this speech genre from moral and ethical and legal points of view. The article reveals the dependence of the linguistic form of conceptualization of negative evaluation on communicative and ethical competence, the formation of which depends on the conceptual certainty of the speech genre. The author concludes that the utilitarian and pragmatic borrowing of communicative patterns from a foreign culture can be a threat to the spiritual and moral state of society.
