You are holding more than 500 pages of combined wisdom on Technology Enhanced Learning (TEL) in your hands! With the advance of metadata, standards, learning objects, Web 2. 0 approaches to rip, mix and burn learning, wikis, blogs, syndication, user-generated content, W- based video, games and the ubiquitous availability of computing devices we can and have to offer more flexible learning services on a global scale. As one of the objectives of the 7th Framework Program of the European Commission puts it: We need “responsive environments for technology-enhanced learning that motivate, engage and inspire learners, and which are embedded in the business processes and human resources management systems of organizations. � An important challenge is to form a bridge between informal learning strategies of the knowledge society and formal competence development programs of organizations. After the success of EC-TEL 2006, the 2nd European Conference on Technology Enhanced Learning (EC-TEL 2007) provided a unique forum for all research related to technology enhanced learning, including its interactions with knowledge management, business processes and work environments. This is a competitive and broad forum for technology enhanced learning research in Europe and world-wide through specialized workshops, the doctoral consortium and the main conference. EC- TEL 2007 provided unique networking possibilities for participating researchers throughout the week and included project meetings and discussions for ongoing and new research activities supported by the European Commission.
