Interpreting mathematics as a discourse includes three claims: that there are forms of mathematics-reality transitions, that mathematics includes actions, and that mathematics includes a political dimension. Through a ...

This research proposes the teaching of mathematics in the secondary school by means of the Study and Research Paths (SRP). A longitudinal analysis has been carried out during two years with secondary school students (aged ...

We contribute a new algebraic method for computing the orthogonal projections of a point onto a rational algebraic surface embedded in the three-dimensional projective space. This problem is first turned into the computation ...

Background: Among the plurality of themes addressed by curricular studies, the nature of decision-making processes involving education professionals has guided some research agendas. Delineated by one of those agendas, ...

This dissertation presents the development of activities related to the teaching of rational numbers in fractional form so diverse and unique to the teacher and the students, through the exploitation of that content with ...

We improve upon the method of Zhu and Zhu [A method for directly finding the denominator values of rational interpolants, J. Comput. Appl. Math. 148 (2002) 341-348] for finding the denominator values of rational interpolants, ...
