“O que descobriram?” Tarefas e discussões coletivas usando diferentes representações durante e após estudos de aula

Abstract

Based in a case study, we seek to understand to what extent a teacher’s participation in lesson studies influences her teaching practice. Data collection included participant observation (doing a research journal and audio/video recording), document collection (tasks and lesson plans) and interview. The results suggest that participating in several lesson studies, planning whole-class discussions from the students’ answers, influenced the teachers’ practice. She proposed a task that allowed students to make connections between representations, as in the lesson studies, and, in the whole-class discussion, she encouraged several students to participate and challenged them to go beyond the task, which she did not do in the lesson studies.
