Connecting Gestures and Images with Concepts in Geometry.

The research aimed to analyze how students identified concepts of Euclidean geometric entities, their properties, and relations, through gestures with the use of a game. The investigation is characterized, regarding technical procedures, as participant research with a qualitative approach and was carried out with high school students in a private school. The analyses performed, via categorization of the gestures used, indicated that students produce gestures more efficiently when they have a mental image of the geometric entity to be represented. The research also showed that those who play the role of observers in the game, identify the gesture produced when they have knowledge of the concept attached to it. [ABSTRACT FROM AUTHOR]
