    Internet e softwares de geometria dinâmica como atores na produção matemática online
    (2008) SANTOS, Silvana Cláudia; BORBA, Marcelo de Carvalho
    In this article, we present examples of how spatial Euclidean geometry activities can be proposed, developed, and discussed at a distance in a virtual learning environment using a dynamic geometry software. Using a qualitative research approach, we collected data in a university extension distance course offered to mathematics teachers. In this study, we emphasize the way different interfaces, such as chat, shape the elaboration of the geometry activities that were developed in this environment. We end by presenting perspectives on mathematical production drawing on our experience with the development of a new virtual learning environment and a geometry software for the Web, both associated with a project in which our research group is participating. We also discuss, based on an "empirical" study, how the model for a course, as well as the media used, condition mathematical production, and how new interfaces can transform it.
