We are interested in understanding how digital technologies, for example mobile phones, can be used to support learning in developing regions across the globe, including here in the UK. We explore the nature and extent of different 'digital divides' between and within social groups and focus on how technologies provide opportunities for building shared understandings across continents. We want to help people develop their expertise in the design of learning activities through a range of participatory projects, run with a strong social justice agenda - aiming to reduce levels of digital exclusion and increase engagement across different populations.
