Abstract : This research deals with the learning of the notion of property as a subordination relation between the data and the conclusion. The choices in the structure of this education are based on a work of distinction between the data and the conclusion in a statement. This distinction is necessary for the reinvestment of the properties in the deductive reasoning. From the works of Vygotsky on the semiotic mediation and the works of Rabardel and Trouche on the instrumentation, we conceived situations, integrating a dynamic geometry software, to introduce the properties. The tool dragging of the software is used to carry out the data of a property. Students work on “soft” constructions, stemming from the dragging, where the new characteristics are short-lived. The process of semiotic mediation is at the begging of the construction, by the student, of the instrument Dragging, it continues during the collectives' discussions with the teacher. The construction of the link between the data and the conclusion leans on the use of the dynamism of the environment but also on the interaction between the visual and discursive registers. We studied how the students appropriate the properties, the relation between the data and the conclusion through the study of:
¬ The construction of the expected dragging instrument during the activities with Cabri
¬ The coordination between the graphic and discursive registers in relation with the process of semiotic mediation
