Procuramos perceber através da análise das falas dos alunos como eles expressaram as soluções encontradas para um exercício de raciocínio que solicitava que descrevessem e explicassem o funcionamento de um sarilho. Após a leitura da história infantil Tão simples e tão úteis, foi distribuído o exercício de raciocínio aos alunos que, em grupos, discutiram as possíveis soluções. Em seguida os grupos foram desfeitos e os alunos, dispostos em roda socializaram suas idéias. Neste artigo apresentamos a análise das falas ocorridas em alguns episódios de ensino selecionados durante a discussão na roda.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[This research is a case study undertaken among second year’s elementary school students. We searched through students discourses’ analysis how they expressed the solutions found for a given exercise which asked they to describe and explain the winch’s operation. After the reading of a story called "Tão simples e tão úteis" (So simple and so useful) it was given to the sample of students a task. Divided into groups, the students dis-cussed the possible solution to it. Afterwards the groups were undone and the students, disposed in a circle, socialized their ideas. In this article we present an analysis of the talks occurred in some teaching episodes se-lected during the circle discussions.]]></p></abstract>
