Exploring High School Students' Arguments While Engaged in Solving a Dynamic Geometry Task

• In Event: Dynamic Geometry and Task

Description

Dynamic geometry environments (DGEs) have been used for many years to support mathematics teaching and learning, enabling users to create and manipulate geometric objects while preserving the properties used in their construction. Research indicates that DGEs can facilitate students' development of conjectures, enhance mathematical reasoning, and support proof construction by allowing them to explore geometric relationships and observe invariants. This study investigates how students use DGEs to develop conjectures and arguments while solving a geometry problem. This study contributes to the understanding of technology’s role in mathematical reasoning at the secondary level.
