**2.9 Open educational resources**

Open Education Resources (OERs) constitute one of the foremost technology trends in higher education, which are cost-effective and accessible to both teachers and students. OER includes any learning material that can be freely accessed by students and teachers, thus being in the public domain, thereby making education accessible and affordable for all. UNESCO is the only international organization that sets out a framework for a dedicated OER Program. However, OERs exist for many years, and no major developments have been observed in this area. Social networking has become one of the important platforms for collaboration for learning, which is also an approach for improving open educational resources and forming online student communities for sharing knowledge.
