Dissertação Acesso aberto (Open Access) A conversão de registros de representações semióticas no estudo de sistemas de equações algébricas lineares(Universidade Federal do Pará, 2008-06-13) PANTOJA, Lígia Françoise Lemos; GUERRA, Renato Borges; http://lattes.cnpq.br/3199659904537033This work is the proposal of a didactic streak to the teaching of Linear Systems of Algebraic Equations in which sought to establish a connection between the method of substitution and the method of stages through the conversion of records of representation. The aim of the proposal was to check whether the students can complete the connection between the two methods developing the conversion of the method of substitution in the method of characterizing staggering thus, the learning of the subject studied math, according to records of representation theory of semiotics Raimund Duval. The research was conducted with middle school students in a school of public state of the city of Belem and the results pointed to the establishment of a connection between the two methods employed in the process of resolution of systems.
