Relations between lesson planning and mathematical learning in a Lesson Study in Southern Brazil

Abstract

This article aims to understand the relationship between lesson planning and student learning in a lesson study carried out in southern Brazil. It involves a qualitative investigation with an interpretive perspective. The data were produced with three teachers, from eight sessions of a lesson study. We analyzed the transcripts of the meetings, the planned tasks, and the students’ resolutions. Regarding the topic to be taught, the objective of the lesson, and the task, the results show that the teachers were concerned with the students’ difficulties and with adapting the task, considering the context. Regarding the students’ learning, the teachers anticipated some possibilities of task resolution, of forwarding the class, and of evaluating the task, but they considered that the learning objective was not reached. In fact, the adaptation of a task involving proportionality did not allow the students to reach the intended concept of division in a natural way. It concludes that there is a need to participate in other lesson studies, from the perspective of changes in professional practices, with particular attention to the selection of tasks to achieve the proposed learning objective.
