Resumo: This text brings some reflections concerning the difficulties identified in the resolution of activities of a test involving affine and quadratic functions presented by eighteen academics from the second year of the Mathematics Licentiate course. The activities were developed based on the Theory of Registers of Semiotic Representation, whose resolutions revealed the difficulty in converting graphic and natural language registers to the algebraic symbolic register. Difficulties were also observed regarding the use of mathematical arguments to justify the strategies used to solve the phenomena presented. The lack of formal organization in the resolutions was another aspect revealed by the academics through the test activities. From these difficulties, we interpret the conversion from graphic to algebraic symbolic as a didactic obstacle and the conversion from natural language to algebraic symbolic as an epistemological obstacle for the acquisition of affine and quadratic functions knowledges.

As atividades foram elaboradas com base na Teoria dos Registros de Representação Semiótica, cujas resoluções revelaram a dificuldade na conversão dos registros gráfico e da língua natural para o registro simbólico algébrico. Foram verificadas dificuldades também quanto ao uso de argumentos matemáticos para justificar as estratégias utilizadas para resolução dos fenômenos apresentados. A falta de organização formal nas resoluções foi outro aspecto revelado pelos acadêmicos por meio das atividades do teste. A partir dessas dificuldades constatou-se que a conversão do registro gráfico para simbólico algébrico constitui-se em obstáculo didático e a conversão do registro em língua natural para o simbólico algébrico em obstáculo epistemológico para a aquisição do conhecimento de funções afim e quadrática.Universidade Federal de Santa Catarina2023-05-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/alexandria/article/view/8710210.5007/1982-5153.2023.e87102Alexandria: Revista de Educação em Ciência e Tecnologia; v. 16 n. 1 (2023); 183-2051982-5153reponame:Alexandria (Florianópolis)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/alexandria/article/view/87102/53193http://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessAgostinetto Antunes, Francieli CristinaIgnatius Nogueira, Clélia Maria Bessa de Menezes, Marcus 2023-05-22T13:42:50Zoai:periodicos.ufsc.br:article/87102Revistahttps://periodicos.ufsc.br/index.php/alexandria/oai1982-51531982-5153opendoar:2023-05-22T13:42:50Alexandria (Florianópolis) - Universidade Federal de Santa Catarina (UFSC)false
