The primary aims of this working group are to exchange ideas/plans for future extensions of GeoGebra and organise its developer community. Current projects include extending the statistics and spreadsheet capabilities of GeoGebra and improving CAS integration into the software. In addition, some work has been already carried out on the 3D extension of GeoGebra. 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. The focus areas of this working group include: * Features & Wishlist * Extensions: exploring possible extensions of GeoGebra features like Spreadsheet, CAS, 3D, etc. * Online Systems: integration into online systems like Moodle, Sage, WebWork, etc. * Wishlist & Roadmap: developing and evaluating a wish list for future extensions * Organization * User Community: new website, GeoGebraWiki, material manager * Developer Community: distributing work and managing the open-source developer community * Support * Projects: listing existing projects; developing ideas for research and development projects; * Funding: exploring resources for future developments and supporting developers [less ▲]

GeoGebra 3.2 – The new Spreadsheet View

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 ▲]

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. [less ▲]

In this paper we describe the ongoing effort to specify a common file format for Interactive or Dynamic Geometry Systems (DGS). Our approach is based on the OpenMath standard, and uses its flexible extension mechanisms like Content Dictionaries. We discuss the various design decisions, the Content Dictionaries that have been defined, as well as open questions to be resolved. [less ▲]

The main objective of the Intergeo Project (http://i2geo.net) is to make digital content for mathematics teaching in Europe more accessible, usable and exploitable. So far, Intergeo provides an Internet platform that offers content in a searchable and metadata-tagged form. In particular, teachers can search for suitable content based on the key concepts and themes of their curriculum. Once found, the content can be used either directly on the web or using the software of choice. Another very important aspect is that all material used in the classroom should adhere to certain pedagogical and mathematical quality standards. Intergeo facilitates the evaluation of material by means of a quality-testing framework that aids teachers and researchers in assessing the educational value of the digital content. The questionnaire used for this can be answered both quickly as well as in depth. In this workshop we will show how to use the platform and how to participate in the project as a user or by becoming an associate partner. Also, we will help software and tool authors to be able to read and write the new standard format for interactive geometry, i2g. [less ▲]
