OER is in line with the statutory engagement of UNESCO to open interchange of thoughts and information. Freely accessible teaching tools for adjustment and re-use can extend access to stronger performance teaching at a reduced price. The fast development of technology-mediated methods to achieve worldwide teaching has accentuated OER's distribution and significance and enhanced this global trend. Since 2002, UNESCO and its collaborators have been collaborating in this area through the first and second World OER Congresses and associated events to promote the use of OER to increase links to value lifelong learning.
