International GeoGebra Institute: nurturing a community to assist the integration of the open-source mathematics software GeoGebra into mathematics teaching

GeoGebra is a free open-source dynamic mathematics software that is a versatile tool for visualizing mathematical concepts from elementary through university level. Without any promotion and organised training GeoGebra has been discovered and used by tens of thousands of enthusiastic teachers and researchers around the world. In the past four years, an extensive self-supporting user community was formed by users of GeoGebra and they share interactive teaching materials on the GeoGebraWiki and support fellow users through the GeoGebraForum. Volunteers from this community have also translated GeoGebra to 42 languages offering great opportunity to use the software in local languages and in multicultural environments. To be able to support such extensive user community, we established the International GeoGebra Institute (IGI). The principle aims of IGI are to develop a platform to offer training and support for teachers and to coordinate research in relation to GeoGebra. During the past year, eight local GeoGebra institutes were established. In this talk, we will share our ideas about IGI and outline the current developments of this project. We hope to nurture a network of people who can contribute to any aspects of GeoGebra based on their interests.
