Open education aims to remove barriers to learning through open courses, open educational resources, and open pedagogies. Open courses like MOOCs had over 230,000 courses in 2012 enrolling over 25,000 students on average, though only 15% completed courses. Open educational resources are learning materials that can be modified and shared under open licenses. Benefits of open education include helping democratize and lifelong learning, allowing students to explore new industries, and providing flexibility for instructors.
