Lower levels include finding existing OER to supplement teaching, while higher levels involve designing courses around reused content and sharing one's own resources openly. Barriers to reuse include discoverability, quality, and licensing issues. Enablers include institutional support and acceptance by students. The document emphasizes using open licenses like CC BY to maximize sharing and reuse of educational materials.
