In spite of the remarkable efforts by countries around the world to ensure education for all, more than one-third of the world’s adults do not have access to education due to geographical constraints, cultural and social barriers and lack of educational infrastructure. These problems constrain efforts to meet basic learning needs. Conversely, open and distance learning which is designed to deliver education to students who are not physically present frees learners from constraints of time and place and offers learning opportunities to individuals and groups of learners.
