  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
