These knowledge maps reveal that, despite a decade of large investment in ICTs to benefi t education in OECD countries, and increasing use of ICTs in education in developing countries, important gaps remain in the current knowledge base. In addition, there appears to be a dearth of useful resources for policymakers and donor staff working on education issues in developing countries, identifying what is known to work—and not work—in this field, especially in support of Education For All (EFA) and other education-related Millennium Development Goals (MDGs). The knowledge maps investigate ten topics (impact of ICTs on learning and achievement; monitoring and evaluation; equity issues; costs; current projects and practices; specifi c ICT tools; teaching and ICTs; content and curriculum; policy issues; and school-level issues).
