Open Education Resources (OER) are designed to make education more inclusive, opening up opportunities to those who otherwise couldn’t afford it by alleviating the high cost of course materials.
OER are educational materials that have been licensed for free use and adaptation (e.g. Creative Commons) or do not have copyright restrictions (e.g. the public domain).
OER include a wide range of resources such as textbooks, teaching and learning materials, images, videos, games, lesson plans, worksheets and assessments.
