Report of the First International GeoGebra Conference 2009 July 14 and 15, 2009 at the RISC in Hagenberg near Linz, Austria Abstract The principal aim of the First International GeoGebra Conference 2009 was to discuss the direction and vision the GeoGebra community should take in the future. On July 14th and 15th, 2009, a group of 114 people from 35 countries met for the First International GeoGebra Conference in Hagenberg, Austria at the RISC institute of the Johannes Kepler University Linz. During these two days researchers, developers, and teachers discussed and shared their experiences and ideas concerning GeoGebra in five working groups: Software Development and Online Systems; Teaching Experiences in Primary and Secondary Schools; Creation of Instructional Materials; GeoGebra at Universities and in Teacher Education; GeoGebra Institutes and Research. This report summarizes the GeoGebra related experiences of the conference participants as well as outcomes of the working group discussions and future plans for the development of GeoGebra and its user community.

As an open‐source project with a large user base, the future development of GeoGebra will be substantially influenced by the needs and desires of the GeoGebra user community and by the strength and cohesiveness of the GeoGebra developers. 2.2 Participants First Name Last Name Country E‐mail Miguel Abanades Spain [email protected] Josef Böhm Austria [email protected] 3 First Name Last Name Country E‐mail Francisco Botana Spain [email protected] Janne Cederberg Finland [email protected] Jesús Escribano Spain [email protected] Tatsuyoshi Hamada Japan [email protected]‐u.ac.jp Peter Hofbauer Austria [email protected] Bernát Kalló Hungary [email protected] Pellumb Kllogjeri Albania [email protected] Zoltán Kovács Hungary [email protected] Matija Lokar Slovenia [email protected]‐lj.si Heidi Metzger‐Schuhäker Austria [email protected] Walther Neuper Austria [email protected] Dani Novak USA [email protected] Yasuhide Numata Japan [email protected]‐tokyo.ac.jp Pavel Pech Czech Republic [email protected] Peter Richert Germany peter.richert@fh‐muenster.de Ilya Serbis Russia [email protected] Florian Sonner Germany [email protected] Kurt Söser Austria [email protected] Peter Tierney‐Fife USA ptierney‐[email protected] Eno Tonisson Estonia [email protected] 2.3 Discussion Overview This working group allowed several
