Open Educational Resources (OER) provide free educational materials online from universities and other institutions. They include items like images, articles, lessons, and full courses. OER offer opportunities for lifelong learning to anyone with an internet connection by making information more accessible and affordable. While OER present benefits like reducing education costs and allowing customization of materials, there are also challenges to using OER. It can take time to find high-quality materials and prepare them into a course. Not all students have reliable internet access needed to use OER. Overall, OER are expanding opportunities for education as traditional tuition rates rise.
