ARAVENA DIAZ, María  y  CAAMANO ESPINOZA, Carlos. Levels of geometric reasoning in students of statal schools of Maule Region: Talca, Chile. Relime [online]. 2013, vol.16, n.2, pp.179-211. ISSN 2007-6819.  https://doi.org/10.12802/relime.13.1621.

In this research, financed by the National Fund for Scientific and Technological Development, FONDECYT 1090617, we analyze students' geometric reasoning from a municipal school, with high indices of vulnerability, in the region of Maule, Chile. Therefore, we made a diagnose test based on the Van-Hiele's model and Gutiérrez & Jaime's (1998) distinctive attributes in the reasoning process by considering the subjects students have from sixth grade, primary school, and from second grade, secondary education. The methodology was quantitative like where we took a sample by groups with a proportional allocation in a random sample. The effective sample was of 625 students which were representative of the area. Our main conclusion is that the students have a basic level of geometric reasoning and they have a low acquisition level in reasoning processes.
