| dc.description | In this thesis we explore what secondary students (between 14-15 and 17-18 years old) learn about the concept of solution of a system of linear equations with two unknowns when teachers teach this topic starting with systems of two equations. We also designed a sequence of activities for teaching this topic for secondary students ranging between 14 and 15 years old. According to students´ difficulties detected in this research, we suggest to teach the concept of solution of a system of equations, not restricted to the context of systems of two equations. We could offer students different tasks, where they would face different situations involving two or more linear equations. We also recommend that systems of equations should be presented in different modes of thinking as the ones presented by Sierpinska (2000): synthetic-geometric, analytic-arithmetic and analyticstructural. Different ways of thinking about the mathematical objects will allow students a deeper understanding of them. We think that in this way students will construct a wider vision of the concept of solution of a system of linear equations that will allow them in the future to learn more abstract and general structures. | - |
