Diseño y desarrollo de una ate para la comprensión de la semejanza con soporte en la actividad de visualización

Abstract

The present deepening work arises as a response to the importance of the use of visualization cognitive activity in geometry to recognize aspects of similarity of geometric figures. In this sense, it is proposed to develop a School Technological Activity that allows the student to build and analyze the intrafigural and interfigural relationships between the parts that make up the model of a house and the dynamic representations of parts of the house with Geogebra going to the perception, the speech and the operations between the elements of the representations which are constituted as fundamental elements in the cognitive activity of visualization (Duval, 1998). To answer the guiding question, the design and analysis strategies were selected based on the construction of models and dynamic representations with Geogebra, to promote the development of the mathematical activity of visualization, in the development of an ATE. The ATE was implemented with 3 students from the El Palmar Industrial Technical Educational Institution located in the municipality of Paz de Ariporo Casanare, who were taken as cases for the analysis of the results. The IBD was selected as a research methodology since through it it was possible to respond to the general objective of this degree work: Design and implement a school technological activity that allows students to recognize aspects of the concept of similarity through the construction of prototypes of scale models.
