This paper describes a set of new technologies, tools, paradigms and infrastructures that have been developed and studied by the KMR group. Based on the emerging nextgeneration World Wide Web, the so-called Semantic Web, these developments rely on international learning technology standards to support the sharing of digital content for learning and the building of virtual learning communities, especially in mathematics. 1.

This paper is a short introduction to some aspects of new technologies, tools, paradigms and infrastructures that will influence the development of future ICT-enhanced mathematics learning environments. Its purpose is to inform the mathematics education research community about new learning designs and new avenues of research opened up by these developments, as well as to point to the ongoing research projects at the KMR group that are exploring some of the corresponding issues.
