Pre-service teachers’ discourse when describing and defining geometric solids
Abstract
In this work, we study the mathematical practice of defining among pre-service teachers. This research has been carried out using a sociocultural theoretical framework: the theory of commognition (Sfard, 2008), which considers mathematics as a particular type of discourse and thus the discourse becomes the focus of study. A research instrument was designed with 9 questions about the description and definition of geometric solids, which made it possible to access pre-service teachers’ spoken and written discourse. The analysis of this discourse has allowed the identification of discursive properties (narratives, word use, visual mediators, routines and meta-rules) with the aim of inferring commognitive conflicts whose resolution could lead to mathematical learning.Keywords
