The Movement of Teachers’ Education for Geometry Teaching in the Elementary School

Abstract

This paper reports the organization of a group of
four teachers who planned, developed, and evaluated a teaching proposal.
The aim of this study was to discuss the education of teachers who teach
mathematics for the Elementary School, considering the challenge of organizing
a Guiding Activity for Geometry Teaching. In order to do so, the
researchers referred to the Historical-cultural Theory, more specifically to
the Activity Theory (Leontiev, 1983; 1988) and the Educational Guiding Activity
(Moura, 1996; 2010). It was possible to show that the teachers’ mathematical
knowledge served as guidance for the teaching practices, and that
their sharing proved to be preponderant for their constitution as teachers.
