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.

GeoGebra (www.geogebra.org) is a free, multi-platform, open-source dynamic mathematics software with rapidly growing worldwide popularity. The basic idea of the software is to join dynamic geometry, algebra, and calculus, which other packages treat separately, into a single easy-to-use package for learning and teaching mathematics from elementary through university level. So far GeoGebra’s user interface allowed algebraic (i.e. coordinates of points, equations) and graphical (i.e. points, function graphs) representations of mathematical objects. While coordinates and equations were displayed in the algebra view on the left hand side, their graphical representations could be seen in the graphics view on the right hand side. The release version 3.2 (available in April 2009) adds another – third – view: the spreadsheet view. Now various kinds of mathematical objects – not only numbers – can also be put inside spreadsheet cells. All representations of the same object are linked dynamically and adapt automatically to changes made to any of the representations, no matter how they were initially created. This enables users to connect statistical reasoning with other areas of mathematics. In this presentation we will introduce the new view, present some examples and discuss the opportunities it offers for the teaching and learning of mathematics. [less ▲]

Research indicates that despite the numerous benefits of using technology in mathematics education, the process of embedding technology in classrooms is slow and complex. Most teachers need more than just being provided with technology if the benefits of technology are to be substantially realized. It has been suggested that adequate training and collegial support boost teachers' willingness to integrate technology into their teaching and to develop successful technology-assisted teaching practices. GeoGebra is free open-source dynamic software for mathematics teaching and learning that offers geometry and algebra features in a fully connected software environment. Its pool of free interactive materials and user forum are examples of online collaboration of a world-wide community of mathematics educators. In this poster presentation, we will outline the emergence of the software GeoGebra and its recent developments as well as the first steps towards (using present tense to show that work has already been done) International GeoGebra Institute to be able to offer structured training and support for teachers who are ready to integrate GeoGebra into their classrooms. In addition, we will organize and coordinate research projects in relation to GeoGebra to enhance the development of training and support materials. While our initial plan is to establish an IGI site at Florida Atlantic University (USA), in the long run our goal is to collaborate with colleagues and set up other institutes in various locations around the world.

The basic idea of the software is to join dynamic geometry, algebra, and calculus, which other packages treat separately, into a single easy-to-use package for learning and teaching mathematics from elementary through university level. Participants of this workshop will be introduced to the versatile possibilities of GeoGebra in hands-on activities in geometry, algebra, and calculus. They will learn how to use GeoGebra as a visualization tool for teaching and to create student-engaging interactive online materials. Free software and materials will be provided. No special computer experience is required. [less ▲]

GeoGebra (www.geogebra.org) is free, multi-platform, open-source dynamic mathematics software with rapidly growing worldwide popularity. The basic idea of the software is to join dynamic geometry, algebra, and calculus, which other packages treat separately, into a single easy-to-use package for learning and teaching mathematics from elementary through university level. GeoGebra offers the powerful opportunity for teachers to create interactive online learning environments which have led many teachers to foster experimental and discovery learning for their students. An extensive self-supporting user community shares free interactive teaching materials on the GeoGebraWiki, supports fellow users through a user forum, and has translated GeoGebra to 36 languages. In this poster presentation, we will both present applications of the software and plans for its future development, as well as raise some of the implications of technological developments such as GeoGebra for the pre-service education and inservice professional development of teachers of mathematics.

Research suggests that despite the numerous benefits of using technology in mathematics education, the process of embedding technology in classrooms is slow and complex (Cuban, Kirkpatrick, & Peck, 2001). GeoGebra is open-source software for mathematics teaching and learning that offers geometry, algebra and calculus features in a fully connected and easy-to-use software environment. It is available free of charge and used by thousands of students and teachers around the world in classrooms and at home. In this presentation we will both present applications of GeoGebra for calculus teaching at the high school and college level, as well as raise some of the implications of free and easy-to-use software such as GeoGebra for technology integration into the teaching and learning of calculus.
