Contribuições do Ensino Desenvolvimental e da mediação com tecnologias para o ensino-aprendizagem de Sistemas Lineares

Abstract

The aim of this work is to present a proposal for a study activity on the concept of Linear System through the conjectures of Developmental Teaching proposed by Davydov, which will address a recommendation about the method and didactic application for teaching researchers in Mathematics and Mathematics Education.Being, an investigation that is characterized by the qualitative nature. In this work, at first, we will present a study on the sociocultural character of the individual and its mediation served through the budgets of the Historical-Cultural Theory to understand Davydov's Theory of Developmental Teaching and its analysis for the development of Davydov's formative didactic experiment and their actions, for the construction of the study activity. In the second and third moments, we discussed the use of technologies in teaching and Davydov's mediation through technologies, in addition to presenting the GeoGebra software and reporting on the mathematical applicability with technologies.Finally, in a fourth moment, a survey of the concept of Linear Systems and its logical-historical trajectory was presented, with the presentation of the history behind the conceptualization. From the formalization of the previous moments, the proposal of a study activity is developed with the approach of the use of GeoGebra for solving Linear Systems, using the software as an auxiliary means in the student's teaching-learning process.
