Abstract
Esta pesquisa visa compreender o conhecimento especializado que um professor de matemática possui em
relação à subtração, em cujo processo de ensino utiliza algoritmos abertos baseados em números (método ABN),
utilizando o modelo Mathematics Teacher Specialized Knowledge (MTSK) para sua análise. Para o efeito, foi
realizado um estudo de caso de um professor primário do segundo ano de uma Escola Concertada de Huelva. A
partir das transcrições das gravações de quatro atividades em que a subtração é trabalhada, bem como de uma
posterior entrevista semiestruturada, foram obtidas evidências e indícios que mostram que o professor possui
conhecimento especializado em subdomínios de conhecimento de conteúdo e conhecimento didático conteúdo,
o que nos permite presumir uma relação entre esse conhecimento e a formação docente no método ABN.
This research focuses on understanding the specialized knowledge that a mathematics teacher has in relation to subtraction, in whose teaching process uses Open Algorithms Based on Numbers (ABN method), using the Mathematics Teacher Specialized Knowledge (MTSK) model to your analysis. Therefore, it has carried out a case study about a second primary teacher from Concerted School in Huelva. On the other hand, the transcripts of the recordings of four activities in which the subtraction is worked, as well as from a subsequent semistructured interview have obtained evidences and indications that show the teacher has specialized knowledge in subdomains about knowledge of contents and didactic knowledge, which allow us to presume a relationship between theses knowledges and teacher training in the ABN method.
