Abstract:
The analysis of the educational practise is an important part of professional development, as it permits reflection on the various issues that condition the teaching and learning processes. The complexity of these processes requires the integration and application of theoretical tools that facilitate carrying out a systemic analysis. The perspectives required to analyse mathematical practice in the classroom are diverse, but can be usefully grouped in three categories: 1) the epistemic perspective, the goal of which is to provide adequate tools - what we shall refer to as "onto-semiotic" tools - for analysing the objects and mathematical processes (personal and institutional) that intervene in an instructional process; 2) the normative perspective, which should furnish us with the tools for analysing the sociomathematical and social norms that regulate the study process; and, 3) the axiological perspective, which provides us with the tools to evaluate the efficacy of teachers' own practice. In this paper, we centre our study on the epistemic perspective and use the notions drawn from the onto-semiotic approach to mathematical cognition in analysing a textbook task.

Abstract:
We adapt the onto-semiotic approach to research in mathematics education developed by Godino and his colleagues (e.g., Font, D'Amore & Godino, 2007; Godino, Batanero & Roa, 2005) in order to better understand certain disparities in the interpretation of classroom socio-mathematical norms (Yackel & Cobb, 1996). In this approach, the experience of Disparities in the interpretation of Norms Can Be conceptualizad as the experience of semiotic Conflicts. We explore semiotic Conflicts in the mathematics classroom in relation to: 1) Mathematical Practices That Are Being Developed Within the classroom, 2) socio-Mathematical Norms That Intervene in the orchestration of the practices, and 3) Differences in the interpretation of the norms.
