Open educational resources (OERs) are teaching, learning, and research resources that are freely available for re-use (and often remixing). OERs come in a variety of formats including course materials or modules, textbooks, videos, assessment tools, or digital exhibits. There are several growing repositories of OERs including: OER Commons and MERLOT.
As OERs become more widely available they are gaining currency as worthwhile teaching tools that present cost savings to schools and students. The U.S. Department of Education recently announced that they will hire and open education adviser. The adviser will work to connect educators from both K-12 schools and higher ed with OERs that can be integrated into their curricula.
