Construindo um modelo de análise da prática lectiva numa aula de Matemática

Teaching practice can be seen in different perspectives; one of them is the cognitive perspective. We present a model that, starting from teaching practice, allows us to examine which cognitions are at stake when teachers are immersed in their practice, and also the ways in which those cognitions arerelated and what is their role in the teaching process. The establishment of such a model allows us to simplify something so complex as the teaching process. In this paper we present the process of construction of such a model, in an elementary 4th grade class in which the teacher makes a dialogued review of the differences between squares and rectangles regardingmeasurements and number of sides. The model emphasizes the cognition evidenced by the teacher as well as the relations between them and the actions he takes. We finish by presenting the possible implications of the use of this model in the initial and continuing training of teachers.KeywordsTeaching model; Cognitions; Practice; Mathematics
