Open Educational Resources (OER) are free or low-cost alternatives to costly commercial classroom materials. OER materials are not just textbooks! OER materials include syllabi, tutorials, quiz banks, slides, textbooks, and even full courses.
They are peer-reviewed and published with an open license, which gives professors the ability to download, edit, and share them without worrying about copyright.
A major advantage of OER is the ability for anyone to remix, reuse, and revise the material to better fit their course objectives.
While OER are often used or assigned in class, they can also serve as tutorials or supplemental resources to support your learning! These free OER materials, written or designed by chemistry professors, provide extra background explanations and practice for strengthening your knowledge.
