Resumo: |
This thesis has the purpose of observing how students from the 2nd year of High School make use of geometric transformations of space when interacting with the environment of Dynamic Geometry Cabri 3D, as well as what kind of reasoning they use when developing activities concerning this content. Thereby, this work intends to answer the following questions: How do students make use of the tools and/or resources of Cabri 3D in order to learn the geometric transformations of space? How does the integration of Cabri 3D interfere in the process of learning these geometric transformations? The methodology adopted used aspects of Didactics Engineering, according to Artigue (1988). The theoretical foundation was the Instrumental Approach of Rabardel (1995) to enable the understanding of how students interact with Cabri 3D and which contents they make use of during the development of a sequence of activities. In addition, the theory of Register of Semiotics Representation of Duval (1995) was used, specifically the apprehensions of a figure. The analyses of the activities which involve notions of geometrical transformation of space helped us realize other possibilities that the instruments can give the subjects as well as different ways of organizing the actions. Moreover, the activities made the development of different strategies easier for students who used the Cabri 3D and students established relationships between the software and mathematical knowledge. We verified the occurrence of Instrumental Genesis, because the students actions showed pre-established schemes or the development of new schemes. At the same time, the use of Cabri 3D helped the perceptive apprehension of the figures and allowed to become dynamic. This way, Cabri 3D permitted the dynamic figural register, facilitated the positional modification and the other modifications of figures, and their visualization |
