Noções de unidade de medida e capacidade volumétrica no 4º ano: aprendizagens a partir de um estudo de aula

Abstract

The lesson study is an approach of professional development based on aspects of collaboration and reflection, focusing on teacher's practice, her learning and the student-driven learning. This research aims to identify and discuss the main contributions of the lesson study on the approaching of notions of unit of measurement and volumetric capacity in the 4th year of elementary school. With this perspective, a lesson study has been organized with teachers from the 1st to the 5th grade of the initial grades of elementary school in a public-chain school in the region of Alto Uruguay of Rio Grande do Sul, in which was developed and planned an exploratory task for a 4th grade class of the initial levels of elementary school, aiming to answer the following problem "What are the contributions of the class study to address the notions of unit of measurement and volumetric capacity in a 4-year-old class of the early years of elementary school?". The research, of a qualitative and field nature, adopted Laurence Bardin's Content Analysis (2016) as a data analysis techniques. The empirical material was constituted from the field notes, with the transcriptions of the audio recordings of the meetings, the teachers' logbook, the students' resolution sheets and an interview with the teachers. The empirical material's analysis and interpretation enabled the constitution of three analysis categories such as Professional Learning for teachers, Collaborative planning and Student's learning. The Professional Learning for teachers category enabled professional development for the teachers because of collaboration and reflections. Also, the Collaborative planning category enabled the sharing, teamwork and reflection about the practice, about whom, its modification. The category Student's learning involves strategy development, explanation and conclusions starting with collaborative teamwork. Finally, the research points that the relation and contribution between those three categories enhances the learning of basic notions of measurement and volumetric capacity, being based on the preparing of specific explanatory tasks about this topic synergizing with the class learning necessities.
