Title: Topic Study Group No. 20: Visualization in the Teaching and Learning of Mathematics
Abstract: The TSG 20 aimed to focus on issues in visualization in the teaching and learning of mathematics at all levels.The group welcomed studies that tackle wide range of issues including: • What is the role of visualization within and across mathematical knowledge disciplines?• Are there kinds, qualities, and/or hierarchies of visualization and visual skills?• How do learners from different cultural contexts and of varying levels of ability and disability employ visualization in learning mathematics?• Considering recent advances on embodied cognition in mathematics, what theoretical frameworks could link visual and haptic modalities in an effective manner?• What theories on visualization can take into account the specific cognitive nature of mathematical activity and thinking?• What methodological considerations must be accounted for in investigations that focus on visualization?How should tasks, instruments, and measures be designed that will enable investigators to assess changes in students' understanding and learning?• What aspects of mathematics teacher education programs will help teachers understand the affordances and challenges of using visualization as a learning tool in mathematics?• What visual-based tasks can foster creativity leading to meaningful mathematical knowledge?Further, are visual-driven students more creative than nonvisual and other types of learners?In particular, we note how recent and emerging
