Open Education is a stance and movement started by some academia and educator bodies that favors creating broad access to learning and training. The philosophy behind this movement is to enable inclusiveness in societies and eliminate barriers of inequality that may stop some from getting access to formal learning opportunities.

One such Open Education resource is Massachusetts Institute of Technology (MIT)’s Open Courseware.
Since 2001, MIT OpenCourseWare has been creating new opportunities for millions of learners and educators, sharing Open Educational Resources (OER) from MIT and helping to lead a global revolution in free access to knowledge.
