Résumé
In the context of ReMath European Project, new representations of algebraic expressions were introduced in two systems Aplusix and AlNuSet. The purpose was to provide an answer to educational hypothesis concerning the importance to use representation registers for algebraic learning. We have used Duval (1993), Peirce (1998) and Sfard (1991) researches to frame our work. Different choices concerning representations were made in the two systems that leaded their internal evolution such as the interface structure. In this paper, we will show how these theoretical frameworks shape the conception of these two artefacts. Furthermore, we will analyse how our choices affected the actions and feedbacks allowed in these systems. Finally, we will present new types of tasks that these advanced artifacts allow integrating to perform.
