Peer mentoring has been used as a tool to ensure students’ success in higher education (Husband & Jacob, 2009; Yomtov et. al., 2015). This study investigated the discourse of university-level peer mentoring from a sociolinguistic perspective. The participants were first-year Linguistics undergraduates at a university in Vietnam, who were invited to join a peer mentoring program in which four or five student-mentees work with one student-mentor to improve their English listening and speaking skills. Mentoring activities consisted of both face-to-face meeting and email correspondence and were designed with support from the course instructor. | The discourse of peer mentoring From mentors perspectives
