Open Education addresses barriers to learning by engaging open education practices in the classroom and through the development and use of open educational resources.
Open Practice engages students in collaborative knowledge creations that are then openly shared, often through networked technologies.
Open Educational Resources (OER) are teaching and learning resources made freely available through the public domain or open copyright licenses. They can include syllabi, reading lists, handouts and course readings, PowerPoint slides, audio and videos recordings, computer software, mobile apps etc.
