ARAVENA, María; CAAMANO, Carlos  e  GIMENEZ, Joaquín. Mathematical models through projects. Relime [online]. 2008, vol.11, n.1, pp.49-92. ISSN 2007-6819.

In this research we analyze the mathematical production of a group of secondary students when faced with the task of projects based on the modelization of situations. In the development and implementation of the didactic proposal several studies were considered that illustrated the benefits of introducing this type of work into the classroom as much to overcome obstacles and difficulties as to develop mathematical skills. In order to analyze students' production, the object of this case study, categories were designed to enable the evaluation of this methodology. On a results level, there is a manifest development of cognitive and metacognitive capacities and of transversal formation, in addition to an efficient performance in the utilization of concepts and mathematical processes.
