I often tell faculty interested in online teaching that it requires a fundamental change in mindset from content creator to content curator. Faculty are used to creating their lectures from scratch for face-to-face courses, but the wealth of good educational content on the web makes that a waste of time for most purposes. Unlike face-to-face lectures, digital learning content is preserved and thus can be reused. This means that an instructor's value is not in the knowledge in his or her head but rather the abilities to discern good from bad content and to organize resources and modules into a format that creates learning, including content created elsewhere.
