Estrategia visual en la generalización de pautas lineales

Resum

In this paper the role played by the drawing included in linear generalizing problems is outlined. The main focus is on the generalization developed by secondary education students. The research has been conducted over a population of 13 to 18 year old students. A visual strategy is identified and some modalities described. The Dorfler theoretical framework for the process of generalization is used to analize the students behaviour. Finally we conclude with some didactical remarks.
