Technologies for collective use, interaction and learning: reflections from a math class using a projector

Abstract

This article discusses learning movements in a mathematics class develop using a projector and the GeoGebra software for the study of exponential functions graphs. The discussion was guided by a theoretical construction called Collective Actions Cycle, based on the Jose Armando Valente ideas about the Actions Cycle, and on the work Parangolé by Hélio Oiticica plastic artist.  We sought to observe whether the Collective Actions Cycle, initially proposed to think the digital whiteboards use, could contribute to thinking and analyzing classes with the projectors use. The discussion showed that the screen sharing through a projector can provide opportunities for individuals and collective learning movements from the interaction between subjects and between them and technology. It was also evidente that the interactions that constitute these learning movements are more associated with the teacher’s actions and the choice of the software and activities.
