title = "Understanding geometric proofs: Scaffolding pre-service mathematics teacher students through dynamic geometry system (dgs) and flow-chart proof",
abstract = "The objective of this paper is to discuss the pedagogic potential that is offered by the use of a flowchart proof with open problems and a Dynamic Geometry System in understanding geometric proofs by pre-service mathematics student teachers at an Indonesian university. Based on a literature review, we discuss aspects and levels of understanding of geometric proof and how to assess students{\textquoteright} understanding of the structure of deductive proofs, and how the use of a Digital Geometry System may support students{\textquoteright} understanding of geometric terms and statements, including definitions, postulates, and theorems. The pedagogic focus consists of exploiting the semiotic potential of a DGS, especially the use of GeoGebra tools that may function as tools of semiotic mediation to understand the geometry statements and the scaffolding potential of flow-chart proof with open problems in identifying the structure of deductive geometry proofs.",
