This address was given at the Distance Education and Teachers' Training in Africa Conference, Johannesburg, August 2005 as part of the conference's discussion of 'The role of technology in teacher training in Africa'. The paper explores the potential role of mobile digital devices for teacher education in Africa, through the findings of the Digital Education Enhancement Project (DEEP). Four themes emerging from this research are discussed: development, deep learning, democracy and dignity. The paper concludes that these themes set a strong research and development agenda for teacher education, particularly with respect to the way mobile technologies can support the educational challenges of the Millennium Development Goals.
