processes of quantitative reasoning competence in students of the Universidad Simón Bolívar,
San José de Cúcuta, Colombia. The research was based on a descriptive design and had an
intentional sample of 58 students who were studying the sciences and general competencies
elective. For the collection of information, a diagnostic test (pre-test) and a final test (post-test)
were applied, in order to check the incidence of the applied strategy. The results showed a
significant improvement in the final results obtained by the students in each of the processes
formed: interpretation, representation and modeling, and argumentation.
