An IHE-OCW is typically (but not necessarily) a by-product of an existing face-to-face or online course of the Institute. The IHE-OCW educational resources are organized in a course format which contains the non-interactive copyright-free parts of IHE courses to form a coherent set of educational materials that allow for free online self-study.
