Oportunidades de aprendizagem profissional acerca do raciocínio matemático: vivências de uma professora durante um processo formativo professional

Abstract

This research develops on a continuing education project at the Federal Technological University of Paraná (UTFPR) – Cornélio Procópio and Londrina campus, aimed at teachers who teach mathematics at different levels of schooling. The training process was organized based on the PLOT model (Professional Learning Opportunities for Teachers), as it is a model that makes it is possible to promote learning opportunities for teachers, in this context we included the PDR cycle (Planning, Development, Reflection), in which training participants follow the entire process of Planning, Developing and Reflecting of a class. The focus of study in this training, which took place in the first semester of 2023, it was on understanding the essential processes and understandings of Mathematical Reasoning (MR). Starting from this context, the research aimed to analyze the professional learning opportunities (PLO) about Mathematical Reasoning, its processes, and understandings, experienced by a teacher participating in a training process, in the stages of planning, developing, and reflecting on a class. The nature of this study is qualitative and interpretative, and the analysis focused on the data produced by a teacher of Primary School on Early Years, highlighting different OAPs about RM that were declared by her or could be inferred from the data in each of the stages of the PDR cycles. These OAPs were segmented into two groups: Specialized Knowledge of MR and Pedagogical Knowledge of MR, the latter being organized into two categories: Knowledge of MR and teaching and Knowledge of MR and students. In this way, it can be concluded that the promotion of training actions that focus on OAP about MR can result in progress in the student's learning process and improve the proficiency in learning mathematics.
