Gráficas de trayectorias escolares de estudiantes de bachillerato

For school authorities it is important to know how the students of the institution are progressing in their studies, because in this way they can detect any type of difficulties that arise, however, that information is not always known in time. The objective of this research is to propose a methodology that allows to visualize school trajectories of the students and in this way identify the difficulties that students have in mathematics. To show the potential of the methodology, high school students from an Ecuadorian educational institution were investigated between 2015 and 2019, their grades were processed and graphs of school trajectories were generated, which present the evolution of their grades during the school period. Through this methodology, the identification of individual trajectories of low performance is facilitated, in addition, it was found that collaborative activities have higher scores than individual ones, performance differences between courses were also evidenced. The presentation of grades through graphs is a powerful tool for academic management since it facilitates the detection of difficulties and the making of timely decisions.
