Description:
We report on a multimodal register analysis of instances of “doing proofs” in high school geometry. The session has two purposes: (1) to provide a systemic semiotic description of different registers for “doing proofs” in geometry, based on video analyses of classroom episodes; and (2) to demonstrate how multimodal register analysis can be used to examine the activity that occurs in mathematics classrooms.
