Faculty and students may think that “Open Educational Resources” (OERs) equals “free textbooks.” While some OERs are open textbooks, other types and formats of learning tools are OERs as well. Here are a few examples of OERs in different academic areas to spark your interest in how OERs might improve the effectiveness and affordability of instructional materials for students. All these resources (and more!) can be found using UMSL Libraries’ Open Educational Resources Research Guide. See the OER works being used at UMSL here : https://irl.umsl.edu/oer.
