Resumen
Descripción
La visualización desempeña un papel determinante en la comprensión de los fenómenos que subyacen al aprendizaje y enseñanza de las matemáticas, sin embargo, no es un asunto de constatación inmediata y simple, por el contrario, es una cuestión de tratamiento de información cuya complejidad debe ser descrita. En este artículo se explora el rol que juega la visualización asociada a las figuras geométricas en la manera en que algunos textos escolares de mayor uso en el sur-occidente colombiano introducen la enseñanza de las fracciones en los primeros ciclos de la educación básica. Se observó en los libros de texto analizados un desequilibrio entre el número de actividades que privilegian roles potentes a nivel visual y aquellas cuya potencia es moderada o inexistente.
Visualization plays an important role to understand the phenomena that underlie the learning and teaching of mathematics, however, it is not a matter for immediate and easy verification, on the other hand, it is a matter of information processing that describes complexity. This article explores the role that plays the visualization associated with the geometric shapes on the way in which some textbooks that are most widely used in the South-West of Colombia, are in charge of introducing the teaching of fractions during the first levels of basic education. It was observed in the analyzed textbooks an imbalance between the number of activities that promote visually powerful roles and those which power is controlled or non-existent.
