The concept of open educational resources (OER) is revolutionizing traditional teaching by promoting free and accessible educational materials for all learners. OER includes textbooks, course materials, and multimedia content available online without cost, enabling educators to customize and adapt resources to meet student needs. This democratization of knowledge fosters inclusive learning environments, encouraging collaboration and innovation. Additionally, OER supports education equity by removing financial barriers that often inhibit access to quality learning materials. By fostering global collaboration among educators and students, OER enhances collective knowledge and resource sharing, ultimately transforming the educational landscape.
