Diseño y validación de rúbrica para la evaluación de modelación matemática en alumnos de secundaria

Mathematical modeling has taken great relevance in the educational field for more than forty years. This is considered as an option for the teaching of mathematics where problems of reality are incorporated to relate them to the world of mathematics, in such a way that it allows students to see the practical side of mathematics. This article aims to propose a validated rubric to assess the level of mathematical modeling of students in the last grade of secondary school, when they work on solving problems individually. A test with problems was applied to evaluate four phases of mathematical modeling to 43 third-grade students in secondary school. The evaluation of the phases of mathematical modeling of the test was carried out based on a rubric specially designed for this activity. Validation by judging was carried out. The coefficients of Chronbach and Kappa allow us to conclude that the rubric is a reliable and valid instrument to evaluate phases of modeling. This instrument provides an evaluation guide for the teacher interested in promoting the learning of mathematics from the modeling strategy.
