The purpose of the JEM Thematic Network is to make mathematics education more efficient by proper use of technology. JEM does not develop new tools or software solutions but rather advances the proper use of existing tools, services and content. Once an educational organization starts using technology in education there is no turning back. Hence sustainability of the impact of JEM is automatic. JEM will facilitate the academic community to get proper information by organizing workshops, seminars, and, most importantly, by maintaining a web site containing information about technology, content, and of services.
