MIOLA, Adriana Fátima de Souza  y  PEREIRA, Patrícia Sandalo. Uma análise de reflexões e de conhecimentos construídos e mobilizados por um grupo de professores no ensino de números decimais para o sexto ano do ensino fundamental. Práxis Educativa [online]. 2012, vol.07, n.02, pp.533-558. ISSN 1809-4309.

This paper presents an analysis of the knowledge built and mobilized by a group of teachers throughout six meetings about decimal numbers teaching. The theoretical model developed by Lee Shulman about the knowledge basis for teaching was used for the data analysis, with focus on three aspects: the specific, pedagogical and curricular knowledge of content. The group work enabled moments of study, choices, application, and reflection. Results revealed that sharing experience and planning together made the group aware of the need of a knowledge basis, as well as the importance of discussing and planning as a group. They also pointed out that the meetings provided the participants with opportunities of sharing doubts and reflecting upon their practice.

Palabras clave : Mathematical Instruction; Teachers’ Education; Teaching of Decimals.
