This document summarizes David Wiley's presentation on open education at the Nebraska State College System Open Education Summit. The key points are: 1) Wiley discussed how education involves sharing knowledge between teachers and students, and how digital technologies and the internet enable unprecedented sharing. 2) However, copyright restricts copying, distributing, and editing educational content, limiting this potential. Wiley proposes using copyright and open licensing like Creative Commons to explicitly allow sharing through "the 4Rs" of reuse, revise, remix, and redistribute. 3) Open educational resources (OER) are freely available teaching materials that can be openly used and shared under a Creative Commons license. Examples show OER can significantly reduce costs while improving learning outcomes
