Language practices in the maths clasroom, an experience online teaching development for teachers of mathematics

This article describes the constituent link between language and thought, and therefore the importance of language in learning phenomena. The linguistic practices of mathematicians are specific. In class, students learn at the same time mathematical notions and results, and the way in which they are spoken of. We describe here a teaching development unit proposed in the master of Mathematics Education at Polytechnic National Institute, aiming to provide teachers with tools of analysis, as well as examples of tools to work with students.
