GeoGebra is 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 three 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 35 languages offering great opportunity to use the software in local languages and in multicultural environments. However, the project reached a point where its continued success can no longer be sustained only by one person, Markus Hohenwarter the developer of GeoGebra, and an informal user community. Therefore, our aim is to establish International GeoGebra Institutes (IGI) to develop a framework to provide training and support for teachers and to coordinate research in relation to GeoGebra. We hope to nurture a network of people who can contribute to any aspects of GeoGebra based on their interests. In this talk, we will share our ideas about IGI and outline the current developments of this project.
