Teaching Algebra and Geometry with GeoGebra: Preparing Pre-Service Teachers for Middle Grades/Secondary Mathematics Classrooms

GeoGebra is a free, open-source program that combines features of dynamic geometry software, computer algebra systems, and spreadsheet programs. With its unique ability to illuminate both algebraic and geometric concepts, GeoGebra provides a mechanism to improve how mathematics is taught and learned in middle grades/secondary classrooms. Based on personal experiences of demonstrating GeoGebra-based teaching methods to pre-service and in-service middle grades/secondary mathematics teachers, the lead author has used GeoGebra to enhance pre-service and in-service mathematics teachers' mathematical thinking.
