In this talk we describe the ways in which the JEM, Joining Educational Mathematics, thematic network can help in the efforts of educating about accessibility of science, and of mathematics in particular. The JEM network tries to create a community involving all the key players in the arena of mathematical education, from developers of technologies to users of online content.

The presentation introduces the thematic network JEM and its activities. The network social community blends the expertise of developers, authors and of mathematics teachers. The presentation will discuss the web2.0 tools adopted in JEM and how they can be best employed to allow communication within this community.

This talk reports about the recent activities that lead to a JEM exhibit and a WebALT office in the virtual world called Second Life. It will discuss the potential of SL for educational mathematics and show how it is immediately possible to blend traditional mathematics testing with a virtual treasure hunt.

MathML (http://www.w3.org/Math/), OpenMath (http://www.openmath.org), OMDoc (http://www.omdoc.org/) are examples of languages developed for the semantic representation of mathematics on the web and in electronic communications. Such representations can be very exact (for interfacing with computational software), or quite lax and only cater to good typesetting results on the screen. Producing an exact representation is still not widely supported by authoring but the potential benefits for education are large.

Notes and final remarks from attending the @Science Workshop in Paris and learning a lot about accessibility issues of mathematics and science. The workshop was attended by almost everyone working in the area of maths accessibility and provided a wide overview of the issues, the state of the art and the future perspectives. Program and list of abstracts. My notes are unprocessed - they were taken during the talks and used to produce the first 4 slides that I discussed as final summary. If there are imprecisions, please comment.
