The Darakht-e Danesh (‘knowledge tree’) Library for Educators in Afghanistan is Afghanistan's first comprehensive digital educational resource collection. Its purpose is to enhance teacher subject-area knowledge, access and use of learning materials, and to foster more diverse teaching methodologies in order to improve learning outcomes in Afghan classrooms. The Darakht-e Danesh (‘knowledge tree’) Library (DD Library) is a repository of open education resources (OERs) for teachers, teacher trainers, school administrators and others involved in education. The DD Library uses an innovative interactive, multilingual custom-designed web platform, and currently houses over 2,000 resources in 15 subject categories, for both primary and secondary teachers in Afghanistan, in the three languages taught in the Afghan public school system: Dari, Pashto, and English.
