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 ▲]

Interactive Geometry is a way to improve mathematics education with the help of a computer. Using sophisticated software, sketches and figures can be brought to life, comparable to what movies mean to images. Although many examples of helpful activities that were created using Interactive Geometry Software exist, interactive geometry software is still not used regularly in classrooms. In fact, many teachers do not know about the new possibilities, or they do not have access to the necessary resources. The EU-co-funded project Intergeo will attack the three main barriers for a EU-wide adoption of the existing material: missing search facilities, lack of interoperability, and missing quality information.
