NIETO, Rodrigo Zuza  y  BAIRRAL, Marcelo Almeida. “Poliedro é um sólido, correto?”: um estudo com graduandos interagindo em um chat sobre a definição de poliedro. Ciência educ. [online]. 2013, vol.19, n.01, pp.73-88. ISSN 1516-7313.

Educational research studies that analyze the construction of geometric concepts through distance interactions are scarce. This study is focused on pre-service teachers’ understanding about the definition of a polyhedron. The article is based on research that analyses interactions in virtual scenarios of learning. Briefly, we will present the environment that was designed to be a course about star polyhedrons and, later, we analyze the interactions in one of its forms: that of chat. The investigation and analysis of one chat shows that it must move from a global vision to one focused on individual and collective reflections. The chat was shown to be a scenario that improved pre-service teachers’ reflection about the definition of polyhedrons in three areas: in the context of geometric solids; of its elements (faces, vertices and edges); and in the number of dimensions.
