digital library of Interactive Geometry
This paper describes I2Geo, the platform of the Intergeo project enabling math educators throughout Europe to publicly share interactive geometry constructions. This cross-cultural web-based platform makes each resource, be it a construction, a scenario of use, or a complete course, referenceable, editable, and reviewable. It is based on reusable tools, a fine grained ontology of mathematical concepts and skills, together with a description of educational pathways in Europe: together they allow cross-cultural searches. Following the patterns of open educational resources, anyone may participate and contribute, either by commenting, by adding constructions, or by reviewing the quality of a resource. We describe the current platform’s facilities and the technical foundation that are used and will be used for upcoming features as well as the challenges they solve which are quite common to the broader digital mathematical libraries.
