Over the recent years, there has been a growing interest in Open Educational Resources (OER). A similar trend was observed about a decade ago in the concept of Learning Objects, which inevitably faded without really making an impact in real-world educational contexts. A number of repositories were created that contain thousands of learning objects. However, on the consumption side, very little is known in terms of their implementations and impacts on teaching and learning. The same phenomenon is observed with Open Education Educational resources which are by definition learning objects but they are freely available resources available for educators and practitioners to use, reuse, remix and re-contextualise in local contexts. While the use of OER is widespread among educators (similarly to learning objects), however they often happen in discretion, isolation and not really in well-established frameworks (pedagogical, economical and institutional). This paper presents a case study of how OERs have been included in a sustainable and innovative teaching and learning model in three online courses at Diploma, Bachelor and Masters Level. It shows how the inclusion of OERs helped maintain a good quality level, sustain a viable economic model with reduction of tuition fees for learners, increase access and achieve the intended learning outcomes without any negative impact on the learners' experience.
