Open educational resources (OERs)
Open educational resources (OERs) are freely accessible, openly licensed text, media, and other digital assets that are useful for teaching, learning, and assessing as well as for research purposes. It is the leading trend in distance education/open and distance learning domain because of the openness movement.
OER has emerged as a concept with great potential to support educational transformation. While its’ educational value lies in the idea of using resources as an integral method of communication of curriculum in educational courses (i.e. resource-based learning), its transformative power lies in the ease with which such resources, when digitized, can be shared via the Internet. Importantly, there is only one key differentiator between an OER and any other educational resource: its license. Thus, an OER is simply an educational resource that incorporates a license that facilitates reuse, and potentially adaptation, without first requesting permission from the copyright holder. 
Open Access and Open Education Resources (OER) can also be framed within the bigger picture of Open Science.

SU : The SU Postgraduate Office’s Enhancing Postgraduate Environments (EPE) EU project, in collaboration with 5 other South African universities and 6 European universities, is in full swing. EPE looks at all aspects of the postgraduate journey, from before the scholar is admitted, to the practices and processes of the postgraduate experience, through to what happens after graduation. The aim of the project is to support institutional strategizing around postgraduate environments. The EPE website is available at http://postgradenvironments.com/.
