Abstract
Este trabajo presenta una investigación sobre los libros de textos de matemática de uso oficial
en las Instituciones Educativas Públicas del Perú, distribuidos por el Ministerio de Educación.
En ella se analizan las tareas matemáticas con perspectiva en Razonamiento y Demostración
cuando se desarrollan temas relacionados a los números racionales. Esta investigación se
realizó sobre la base teórica de investigaciones realizadas y orientadas por los retos
metodológicos para el análisis de libros de texto en Razonamiento y Demostración planteados
por Gabriel Stylianides. La problemática que motiva la investigación se sitúa en el escenario
escolar de la Educación Básica Regular del Perú. Abordar el tratamiento escolar del número
racional plantea pensar, entre otros aspectos, en la forma que son presentados en los libros de
texto, puesto que estos recursos son de vital importancia en la interacción docente – estudiante
durante los procesos de enseñanza y aprendizaje. Los resultados obtenidos muestran
evidencias importantes para afirmar que los autores de los libros de texto no abordan procesos
involucrados en Razonamiento y Demostración en el desarrollo de los números racionales, sin
embargo en las tareas propuestas hallamos aquellas que sí pueden ser desarrolladas desde la
perspectiva de nuestro marco teórico.
This paper presents a research about mathematics textbooks of official use in the public educational institutions in Perú, they are distributed by the Ministry of Education. In it the mathematics tasks are discussed with Reasoning and Proving perspective when issues of the rational numbers are developed. This research was conducted on the theoretical basis of researches conducted and focused by the methodological challenges for textbooks analysis on Reasoning and Proving approached by Gabriel Stylianides. The problem that motivates the research is in the school situation of Regular Basic Education of Perú. The school treatment address of the rational number, it raises think among other things, in the way that they are presented in the textbooks, since these resources are of vital importance in the interaction teacher - student during the teaching and learning processes. The results show significant evidence to say that the authors of the textbooks do not address processes underlying in Reasoning and Proving in the development of rational numbers, however in the proposed tasks found that those do can be developed since of the perspective of our theoretical framework.
