OpenCourseWare (OCW) and Open Educational Resources (OER) are two new and closely related educational technologies. Both provide open access to learning materials for students and instructors via the Internet. These are for the moment still very young technologies. While they have grown dramatically in just ten years there is still relatively little literature about their application in higher education. This paper will introduce the technologies, discus their potential, and offer some concepts for where researchers may take the topic in the future.
