Speaker positioning in academic instruction: insights from corpus analysis

Abstract While previous research has extensively explored the ways writers project themselves into discourse and engage with readers across various written genres, limited attention has been given to understanding how university lecturers express their stance, i.e., expression of positioning and commitment towards propositions and students. To address this gap, this study proposes a functional framework for analyzing stance features in academic lectures using 160 lecture transcripts from four broad disciplinary divisions: arts and humanities, social sciences, physical sciences, and medical sciences. The analysis focuses on the extent and manner in which lecturers position themselves in discourse to steer students towards their intended interpretations. The findings indicate that lecturers, regardless of their disciplinary background, express their stance through seven distinct functions, including evaluating their level of commitment, posing questions, interacting with the audience, indicating obligations, emphasizing topics, initiating discourse, and previewing exam-related content. The findings have significant pedagogical implications, especially for educators and EAP practitioners seeking to improve lecture comprehension and engagement among students. Understanding how lecturers use language to interact with students and structure academic discourse can empower teachers to adopt similar stances for guiding students in engaging with course materials.
