This document discusses the challenges and opportunities of using open educational resources (OER) in college classrooms. Some of the key challenges include disagreement over what qualifies as "open," lack of assurance about quality and reliability, and time-consuming nature of finding credible materials. However, OERs also provide opportunities such as augmenting curriculums with high-quality resources, including guest lectures via videos, offering inexpensive alternatives to textbooks, and accessing materials from renowned institutions. OER supports the idea that educational resources should be freely available globally.
