Leitura de momentos de uma aula de Matemática à luz das idéias de Vygotsky

Abstract

The author intends in this article to present some class activities on Plane Geometry developed with 5". grade students, describing them and giving them theoretical basis. She searches in Vygotsky's ideas on zones of proximal development and on his process of concept formation, the basis for her work. She also mentions some of Peirce s ideas when dealing with distinct “word” signs.
