A number of researchers at the Lab use sociological and philosophical perspectives to examine the `wider pictureí of education and technology. The sociology of educational technology reminds us that digital technologies are social and historical products carrying constraints on how they are used. Sociologists within the Lab examine how the social relationships, structural arrangements and cultural norms that surround the educational uses of technology shape, influence and bound individual action. The philosophy of educational technology makes explicit the presuppositions that inform the design, use and application of technologies for learning. This in turn reveals significant areas for research ¨ not least the relationships between knowledge, pedagogy, technology and learning.
