Estudos de Aula nas ações de formação de professores de Matemática: reflexões de uma aula no 6º ano

In the present study we seek to evidence a Classroom Study, which was developed in 2019 with a teacher who teaches Mathematics in the 6th year of Elementary School at a municipal school in the city of Sao Paulo. It is a qualitative approach of an interpretative nature. For the structure of the data collection process, we use triangulation. As a result, we observed that the training methodology Lesson Study enabled advances in teachers' practices by carrying out a more theoretically grounded planning based on the handling and study of documents and curricular materials of the Municipal Network of Sao Paulo.
