Dans le cadre du projet Européen ReMath, nous avons entrepris d'introduire de nouvelles représentations des expressions algébriques dans deux logiciels Aplusix et AlNuSet comme réponse à des hypothèses didactiques sur l'importance de la manipulation des registres de représentations pour l'apprentissage de l'algèbre. Nous nous sommes appuyés en particulier sur les travaux de Duval (1993), Peirce (1998) et Sfard (1991). Des choix de représentations différents ont été faits dans ces deux logiciels et qui ont guidé leurs évolutions aussi bien au niveau interne qu'au niveau de l'interface. Nous montrerons dans cet article comment ces cadres théoriques didactiques façonnent la conception de ces deux artefacts numériques et nous analyserons les conséquences de ces choix au niveau des actions et rétroactions permis. Enfin, nous présenterons de nouveaux types de tâches que ces artefacts évolués permettent de faire vivre.

In particular, we relied on the research of Duval (1993), Peirce (1998), and Sfard (1991) to frame our work.

Abstract
In the context of the European Project ReMath, we introduced new representations of algebraic expressions into two software tools Aplusix and AlNuSet. The purpose was to respond to didactical hypotheses concerning the importance of using registers of representation for learning algebra. In particular, we relied on the research of Duval (1993), Peirce (1998), and Sfard (1991) to frame our work. Different choices concerning representations were made in the two software tools that guided their development both internally and in terms of their interface structure. In this paper, we show how those theoretical frameworks shaped the design of both digital artifacts. Furthermore, we analyze how our choices affected the actions and feedback allowed in these tools. Finally, we present new types of tasks that these advanced artifacts allow one to perform.| File | Dimensione | Formato | |
