Educational Technology, in the European arena often referred to as “Technology Enhanced Learning (TEL)”, is a non-traditional and relatively new research field that was born in the past century around the mid-sixties. Even if it was at times regarded as belonging either to pedagogy, information and communication technologies (ICT), cognitive science, or to the specific disciplinary fields where new technology is applied, it has progressively established itself at the international level as an autonomous interdisciplinary research sector with its own journals, conferences, proper funding programmes, university and research centres. For example, in Italy, the National Research Council (CNR) was a pioneer in this field with the establishment, in 1974, of the Institute for Educational Technology (ITD), the only public scientific institution devoted entirely to this sector.
