Description Network of Excellence STELLAR is developing new agenda for Technology Enhanced Learning research and stimulates knowledge exchange between the key European research teams.STELLAR represents the effort of the leading institutions and projects in European TEL to unify our diverse TEL community. This Network of Excellence is motivated by the need for European research on Technology-Enhanced Learning (TEL) to build upon, synergize and extend the valuable work we have started by significantly building capacity in TEL research within Europe, which is required to allow the European Union to achieve its goals via the Bologna Agreement and the execution of the Lisbon Agenda. The European TEL agenda has been set for the last 4 years by the Kaleidoscope network – with a huge strength in pedagogy and scientific excellence, and the Prolearn network with a complimentary strength in technical and professional excellence. The project integrates this excellence and moves on to the higher strategic formation of policy based in leading research. STELLAR moves beyond the earlier networks by setting a new and critical foresight agenda for TEL via an annually reviewed Grand Challenge programme.The Network is executed via a series of integration instruments designed to increase the research capacity of European TEL at all levels. These instruments act as the backbone of an interlocking set of 3 Grand Research Challenge actions, themed as Connecting People, Orchestration and Context. At the most general level the network is reaching out to the wider stakeholder community via the organisation of strategic stakeholder communication vehicles whilst at the other end of the spectrum it takes its strategy and vision to an annual policy maker “Meeting of Minds”. The path between these two key instruments is designed to reach each key community and greatly increase its capacity to address the critical research issues at each level of capacity. The themes of the Network’s instruments is set by the research community as the “Grand Challenge” for TEL. The Grand Challenges vision and strategy has focused so far particularly on interfacing the research framework, the Delphi studies, and trend scouting with the other STELLAR instruments, most notably with the Meeting of the Minds, with the Theme Teams, with the Alpine Rendez-Vous, with the Doctoral Summer and Winter Schools and with the stakeholder community activities.The project is also developing four new instruments: the Folio of TEL Research, the TEL Thesaurus, the TEL Dictionary and the TEL Encyklopedia.The Network of Excellence has set up a special website for the TEL community (researchers, developers, teachers, policy-makers, suppliers etc). This European TEL social media hub helps stakeholders keeping update and engaging with experts in the field.
