MIT OpenCourseWare (OCW) is an initiative of the Massachusetts Institute of Technology (MIT) that makes a significant portion of its undergraduate and graduate course materials available online for free to anyone in the world. It's a prominent example of an EdTech organization dedicated to expanding access to higher education. Instead of offering interactive courses or certifications, OCW's core function is providing access to the educational content itself: lecture notes, syllabi, assignments, exams, and, in many cases, video and audio lectures.

Located at the Massachusetts Institute of Technology in Cambridge, Massachusetts, USA, OCW's primary goal is to disseminate knowledge and promote educational opportunities globally. The materials are freely accessible without registration or fees, allowing individuals to learn at their own pace and convenience. While not a formal degree program, OCW serves as a valuable resource for self-learners, students supplementing their formal education, teachers seeking supplementary materials, and anyone curious about MIT's curriculum.
