Description:
<p>In this paper, we investigate university students' interaction in an attempt to construct a model of elliptic geometry. In order to study the several ways in which geometrical meaning is produced through context and practices, we introduce three different types of use of geometrical concepts, namely as (1) elements of representation of spatial experience, (2) objects of traditional school practice, and (3) constituents of an abstract mathematical theory. The analysis of students' dialog according to this framework reveals how students develop their ability to communicate mathematically and negotiate their meanings. Students with a different use of geometrical concepts were able to interact and understand their peers.</p>
