The Center for Universal Education (CUE) at the Brookings Institution investigates innovations that can rapidly improve education progress, including innovations that use education technology. This brief is the second in a series of Leapfrogging in Education snapshots that provide analyses of CUE's global catalog of education innovations. The ed-tech innovations in CUE’s global catalog are most commonly implemented by the NGO community and the private sector. These innovations can involve the use of desktop and laptop computers, tablets, and mobile phones, and focus on a range of skills including literacy, numeracy, 21st century skills, and digital literacy. Importantly, many ed-tech innovations contribute to playful learning, community engagement, and the unburdening of teachers, and when used in the form of modification or redefinition, can help leapfrog learning. The review of the global catalog identified a lack of effectiveness evaluations. As the field continues to grow, the authors encourage the global education community to conduct more rigorous impact evaluations. At its best, technology can bring efficiencies, reach broader communities, and enhance learning needed to ensure all children and young people receive access to a high-quality, future-ready education.
