The argument from expert opinion as other-oriented reference in disciplinary discussions

Antonio Bova, Francesco Arcidiacono


This paper aims to investigate the types of source on which students base the arguments from expert opinion when used to convince their teacher and classmates to accept their standpoint during disciplinary discussions. Using the model of a critical discussion integrated with the Argumentum Model of Topics as analytical approach, a corpus of 66 arguments from expert opinion were analyzed. The results show that students in most cases refer to scholars and their scientific notions and theories as source of expertise (other-oriented argument). Less frequently, students refer to themselves and their previous personal experience as source of expertise (self-oriented argument).
