Have you ever found something from the internet that could be a perfect resource (image, video, quiz, etc.) for your class, and you spent hours trying to figure out the copyright issues with that resource? You couldn’t find any Terms of Use, and there was no author information, so you didn’t know who to contact to get permission to use it? Wouldn’t it have been nice if that resource somehow said “I’m free to use, no strings attached, you don’t need to ask for my permission because it is already granted”? Open Educational Resources, or OER for short, are an answer to this problem.
