GeoGebra

DESCRIPTION

This overview chronicles the development of GeoGebra from its inception in 2001 through its evolution in the mathematics education landscape until 2008. It highlights key milestones, including the construction of the first prototype, significant academic recognition, and the establishment of a global community of users across 194 countries. The focus on teacher training and support is emphasized, aimed at improving the integration of technology into classrooms. GeoGebra's impact as a powerful dynamic geometry software and computer algebra system is explored through its research and development initiatives.

  1. GeoGebra History 2001-2008 Markus Hohenwarter www.geogebra.org

  2. 2001: The Idea • Course on TI-92 calculator at University of Salzburg • Dynamic Geometry Software: easy to use • Computer Algebra Systems: powerful and versatile

  3. 2001/02: First Prototype • Master’s thesis in Computer Science & Mathematics Educationfinished in March 2002 • European Academic Software Award 2002Ronneby, Sweden(while teaching in high school in Salzburg)

  4. 2004-06: PhD project • PhD project in Mathematics Education on applications of GeoGebra for high schools • Funded by Austrian Academy of Sciences from Feb 2004 to Jan 2006 • 2004: first translation to SpanishGerman awards • 2005: User Forum & GeoGebraWiki • Feb 2006: PhD finished

  5. 2006: Florida • NSF Math & Science PartnershipFlorida Atlantic University & Broward County Schools (2004 - 2009)PIs: Heinz-Otto Peitgen, Richard Voss • Master’s program for Middle School Mathematics Teachers at FAU • Focus on Math Content Knowledge & Technology Integration into Teaching

  6. Visitors on www.geogebra.org

  7. World Wide User Community 39 languages 194 countries 300,000 visitors per month

  8. Status Quo – What’s missing? Not enough training Not enough support for teachers new to technology Limited research on the impact of GeoGebra for teaching and learning of mathematics

  9. 2007: International GeoGebra Institute www.geogebra.org/IGI Teacher Training and SupportIGI provides free workshops and materials for teachers and future GeoGebra trainers to create and support a self-sustaining community of users Research and DevelopmentIGI continues to enhance GeoGebra’s capabilities and ease-of-use, based on extensive feedback from a wide variety of teachers
