Abstract
We study knowledge and competencies of Brazilian university students after an one year course in linear algebra, concerning various aspects: the global landscape of linear algebra as seen by students, how they do cope with modelization problems through linear algebra, what are their knowledge and competencies about the duality of representation equations/parametrization of subspaces of Rn, their ability in calculations for solving linear equations and their understanding of the symbolic algebra used in linear algebra. The results are coherent with such previous studies, which underlined that the learning of linear algebra by students is generally poor after a one year course.
