Exploring the genetic decomposition of interior and exterior angles of polygons with the use of computer programming and GeoGebra
Page: 277
Pre-service mathematics teachers need to have an advanced perspective of geometry concepts and be able to extend and generalize the geometry content they will teach. This study documents the continued refinement of a geometry lesson using computer programming and GeoGebra to iteratively teach generalization over the concept of interior and exterior angles in polygons and, ultimately, helps to refine a previously developed genetic decomposition for continued improvement of this and future lessons.
