Open Educational Resources (OERs) are any type of educational materials that are in the public domain or introduced with an open license. The nature of these open materials means that anyone can legally and freely copy, use, adapt and re-share them. OERs range from textbooks to curricula, syllabi, lecture notes, assignments, tests, projects, audio, video and animation.
You can can make use of OER by defining the content of your video channel publicly available to all and adding a suitable creative commons licence. For more information about OERs, please click on this link here or here.
