Enseñanza de la simetría axial utilizando situaciones adidácticas y SGD Car Metal como medio

Abstract

Title Teaching of axial symmetry using situations a-didacticas and SGD, Car Metal as a means. This degree project is part of institutional use of the dynamic geometry project, directed by the Group EDUMAT, project is implemented in schools of Bogotá and Bucaramanga; It describes and discusses the use of a sequence of didactic situations, linked to the teaching of axial symmetry, with the mediation of the software of dynamic geometry CarMetal (SGD); designed and planned by the Group Edumat and applied in the IED Jasmine Bogota, by researcher Professor. Each situation has phases to didactic and group stages of sunsets in common; during the a-didacticas students work in pairs in various tasks using the software. This proposal shall be based on the theory of didactic situations (TSD) and take as a reference methodology didactic engineering (ID), in order to be able to describe the advantages of the use of the dynamic geometry software CarMetal, as a means of facilitating learning by adaptation and its effects when it is integrated into the design of a teaching sequence. Not only is the application of didactic engineering, but also seize the opportunity to reflect and deepen further, about the development of the processes of teaching geometry, the use of the software and the appropriation and application of theory; We are interested in two processes identified in the theoretical framework: the validation process and the process of institutionalization; We hope to confirm that the interaction with the software encourages learning by adaptation, can be exploited in the process of institutionalization of knowledge. And that the management of the process of institutionalization is a laborious process, which demand changes in concepts and functions by the teacher, in the process of appropriation of the theory. Key words: educational situation, learning by adaptation, situation a-didactica, validation, institutionalization.
