Moving between written descriptions and visual representations of mathematical objects
Guided by: Konstantinos Tatsis

Mathematics is mainly characterised by the different representational systems involved, together with the importance attached to the ability to communicate and move amongst these representations. Especially in geometry, students are requested to deal simultaneously with several representational systems and this requires - among others - the ability to produce descriptions of spatial objects, relationships and transformations. These aspects will be the focus of the working seminar. The participants will be given opportunities to construct, interpret and discuss descriptions of geometrical objects and relationships in order to clarify some of the processes involved in geometrical thinking. Examples of actual data collected in relevant research will be used as stimuli for discussion on the topic.
