Abstract
Reasoning is an important aspect in the understanding and learning of mathematics. This paper
reports on a case study presenting one Australian primary teacher’s reflections regarding the
role played by a professional learning program in her developing understanding of
mathematical reasoning. Examination of the transcripts of two interviews identified changes in
her perceptions of mathematical reasoning by mapping interview responses against the
Mathematical Reasoning Framework (Herbert et al., 2015). This change indicates that a well
planned program of professional learning based on a demsonstration is efficacious in
developing teachers’ understanding of mathematical reasoning.
