Abstract

In the UK, use of dynamic geometry software (DGS) in classrooms has remained limited. Whilst the importance of the teacher’s role is often stated in dynamic geometry research, it has been seldom elaborated. This study aims to address the apparent deficiency in research. By analysing teacher/pupil interactions in a DGS context, the intention is to identify situations and dialogue that are helpful in promoting mathematical thinking. The analysis draws on an instrumental approach to describe such interactions. Elements of instrumental genesis are distinguished in pupils’ dialogue and written work which suggest techniques that teachers can employ to facilitate this process.
