DALLEMOLE, Joseide Justin; GROENWALD, Claudia Lisete Oliveira  e  RUIZ, Lorenzo Moreno. Semiotic representation registers and analytical geometry: an experiment with future teachers. Relime [online]. 2014, vol.17, n.2, pp.131-163. ISSN 2007-6819.  https://doi.org/10.12802/relime.13.1721.

This qualitative case study presents the investigation on Analytical Geometry as a teaching content and the Teaching and Learning Integrated System (SIENA). The aim was to assess the difficulties felt by students in the conversion of registers in Analytical Geometry (straight line and circumference) and the likely contributions SIENA may offer to the identification of such difficulties and the recovery of these contents at an individual's level. The experiment included ten students of the Bachelor's Degree in Mathematics, Lutheran University of Brazil, Canoas. The results indicate that the students felt difficulty to convert the registers language natural, algebraic and graphic, as well as in visualization, interpretation and abstraction. After recovery studies in SIENA the students presented a better performance in tests.
