Open Educational Resources are teaching and learning materials that you may freely use and reuse, without charge. OER often have a Creative Commons or GNU license that state specifically how the material may be used, reused, adapted, and shared.

As a teacher, you could reuse and repurpose material for use in your own classroom, and augment your school's limited resources. A physics teacher could use video from an introductory physics class at MIT, or use interactive simulations from University of Colorado at Boulder's PhET project. Click here to open the PhET project from University of Boulder.
