The concept of sharing educational resources freely around the world, referred to as "open education" or "open courseware", is now gaining mainstream acceptance both inside and outside of the academy and has been adopted by over 200 higher education institutions worldwide. According to the OpenCourseWare Consortium (OCW), open education has three main advantages: access and distribution of knowledge to regions of the world where higher education is not readily available; recruitment and retention of students, as well as curriculum development and research collaboration among faculty; and sustainability of interest in and access to higher education.
Additional advantages cited include the provision of extra help for students taking a similar course around the globe; identification of potential courses by students; freeing of class time, as high-consensus "background" material can be provided online, leaving more time for student‐led education and increased participation in faculty-student discussion time; and providing feedback to faculty who wish to use the recording to review their presentation style.
