Resumen
La presente investigación tuvo por objetivo analizar las articulaciones del registro figural que
desarrollan estudiantes peruanos del quinto de secundaria (15 – 17 años ) al movilizar nociones
de geometría en la construcción del cubo truncado con el ambiente de geometría dinámica Cabri
3D; para ello planteamos la siguiente pregunta de investigación: ¿cómo estudiantes del quinto
de secundaria articulan las aprehensiones del registro figural cuando movilizan nociones de
geometría en la construcción del cubo truncado con el Cabri 3D? En este estudio, tomamos
como referente teórico la Teoría de Registros de Representación Semiótica, centrándonos en el
registro figural y sus aprehensiones. En cuanto a la metodología, optamos por aspectos de la
Ingeniería Didáctica. En la parte experimental, propusimos una secuencia de dos actividades
encaminadas a la construcción del cubo truncado y ocho preguntas asociadas a ellas. La
intención fue que los estudiantes durante el proceso de construcción y resolución de las
preguntas, movilicen nociones de geometría, coordinen registros, desarrollen y articulen
aprehensiones del registro figural. En las diferentes construcciones, especialmente en la del
cubo truncado, los estudiantes desarrollaron y articularon las aprehensiones secuencial,
perceptiva y operatoria; mientras que en la resolución de las preguntas, las aprehensiones
perceptiva, operatoria y discursiva. Finalmente, consideramos que las actividades permitieron
a los estudiantes articular las aprehensiones, mientras movilizaban nociones geométricas, y que
el Cabri 3D fue propicio para trabajar la construcción del cubo truncado por ser un ambiente de
geometría dinámica que cuenta con el arrastre y la manipulación directa; funciones
indispensables para la construcción y análisis de este objeto matemático.
This work had the purpose analyze the interactions of figural register that carry out fifth students secondary to mobilize geometric notions in construction the truncated cube with Cabri 3D and then answer the following research question: how fifth school´s students articulate apprehensions of figural register when mobilized notions of geometry in construction the truncated cube with Cabri 3D? In this study, we took as theoretical reference the Theory of Semiotics Representation Registers focusing on the figural register and apprehensions, and as to the methodology we choose aspects of the Didactic Engineering. In the experimental part, we proposed a sequence of two activities directed at construction the truncated cube and eight questions associated with it. The intention was that students in the process of construction and solving questions mobilize notions of plane and spatial geometry, and develop and articulate apprehensions of figural register. So, in different construction, especially in the truncated cube, the students developed and articulated the sequential, perceptual and operational apprehensions; while that in the solving questions, articuled the perceptive, operative and discursive apprehensions. Finally, we consider the development of activities allowed, students articulate apprehensions while geometric notions mobilized; and that the Cabri 3D was appropriate to work construction the truncated cube to be a dynamic geometry ambient that enables direct manipulation drag and indispensable functions for the construction and analysis of this mathematical object.
