Construcción de los conocimientos en los estudiantes del Noveno Año de E.G.B. paralelo “B” de la Institución “María Helena Salazar de Pérez” con relación a la función lineal-afín y su aplicabilidad en la vida real

Abstract

The learning of mathematics is more significant when working with real situations. My master's thesis describes and demonstrates the learning of linear and related functions through the realization of didactic sequences with contextualized situations, in such a way that my students made learning a real experience. The design of the activities in the didactic sequences was divided into twelve sessions; each of them had its process, particularity and sequentially, thus achieving the pedagogical objective and the motivation to learn. The sessions began with their respective verbal statement arriving at the table of values and graphing the Cartesian plane describing the solutions, analysis or formulas extracted by the students. The incorporation of the TICs (Application of geo-gebra) in the didactic sequences helped to observe and enrich the learning of the linear and related functions, as well as the effective complement of the use of the appropriate didactic material. The achievements are reflected in the evaluations and the rubrics built with the appropriate and fair criteria that were observing the necessary feedback. The self-assessment was carried out daily in the portfolios and allowed to know the arguments that the students gave, reflecting and empowering the activities and the theme. The didactic sequences with contextualized situations constitute a very valuable strategy since not only do they achieve learning, but the real need to learn arises in the student, an indispensable element for the construction of learning.
