Resumo: | Large-scale assessment projects of students´ performance in Brazil use descriptors to indicate abilities that students should develop in order to deal with real-life modeling problems, and one of these abilities is related to solving systems of equations. In this paper, we report on part of a research project developed with first-year students in mathematics courses enrolled in private universities in southern Brazil; one test question was chosen for an indepth analysis of written solutions to a system of linear equations. After classifying the work of the students, ideas about the meanings of symbol and structure were used to discuss difficulties that arose. It is considered that such an analysis can clarify aspects that must be the focus of future studies to help students and teachers to understand some problems presented in large-scale assessments. Keywords: Mathematics Education. System of Equations. Analysis of Solutions. Structure Sense. Assessment. |

Assessment.Os projetos brasileiros de avaliação de larga escala do desempenho dos estudantes apresentam descritores para indicar habilidades que os alunos devem desenvolver para modelar problemas da vida real e uma dessas habilidades está relacionada à resolução de sistemas de equações. Nesse artigo, é relatada parte de um projeto de pesquisa desenvolvido com calouros de disciplinas matemáticas em universidades privadas do sul do Brasil; uma questão do teste foi escolhida para aprofundar a análise das resoluções escritas de um sistema de equações lineares. Depois de classificar as produções dos alunos, foram utilizadas idéias sobre o sentido do símbolo e sentido da estrutura, para discutir as dificuldades apresentadas. Considera-se que esse tipo de análise permite esclarecer aspectos que devem ser focalizados em outras pesquisas, para ajudar estudantes e professores a compreender alguns problemas apresentados nas avaliações de larga escala.
