Curricular Changes in the Tuition of Algebra

Matrices, determinants and lineal systems of equations are the most traditional
contents in the teaching of Algebra in Bachillerato (high-school) level.
Nowadays, the teaching of these contents is based on algorithms related to
matrix operations to solve lineal systems of equations. By using graphics with
CAS we can go beyond the mere explanation of algorithms and focus on problems
applied to real life situations. We are not trying to change the contents but
the methodology to make the teaching and learning processes more efficient.
