Technology in education shouldn’t only be about changing methods of
communicating knowledge – whether via an interactive whiteboard, a
wireless netbook or a smartphone being illicitly used at the back of a
class. It should also be about changing knowledge itself. Yet
researchers, schools and policy-makers have tended to concentrate on how
technology can enhance teaching without considering whether and how it
should change the nature of what is taught. 

This lecture will draw on nearly three decades of research that has
focused on technology and knowledge, and draw some conclusions for
learning and teaching in the 21st century.
