Abstract
This paper explores the role of a problem-centred pedagogy (Collective Argumentation) in providing teachers with practices and tools to implement a problem-centred approach to teaching mathematics in a senior classroom. The paper focuses on a Year 11 lesson that required students to model and communicate the effects of a disease on a body’s immune system. Using transcripts of teachers’ talk the paper provides teacher perceptions of how students draw on the practices of mathematicians to illuminate and to communicate understanding to others. The study reveals that teachers consider that student capacity to act within a problem-centred curriculum, their sense of agency, is enhanced through participating in the practices of Collective Argumentation.
