Open Educational Resources have emerged as one of the most innovative teaching and learning tools as well as a cost-effective mechanism to improve the quality of educational offerings by optimizing the use of available resources. While OER can be used by any student to learn on his/her own, universities (especially Open Universities) that depend on printed distance learning materials can now use the OERs to offer their courses and programmes and thereby reduce the development time of courses and programmes, and also reduce the cost of launching new programmes. However, not many institutions are in a position to actually develop OERs that can be used effectively for teaching and learning in the digital environment. The Commonwealth Educational Media Centre for Asia (CEMCA), realising the need for professional development of teachers, has developed the online professional development programme on OER-based eLearning to promote the use of OER in educational institutions.
