This document discusses open education and open educational resources (OER). It defines open education as forms of education where knowledge and teaching methods are freely shared online. The open education movement is based on sharing knowledge freely and enabling collaboration. OER include textbooks, courseware, activities, and media that can be reused, redistributed, revised, and remixed under open licenses like Creative Commons. Using OER lowers costs, increases access, and allows for adaptable, learner-designed materials through community sharing. The conclusion states that sharing is the basic characteristic of education.
