Open educational resources (OERs) provide several benefits but also some challenges for instructors. The benefits include freeing up instructor time for student feedback, reducing student costs and frustration from changing textbooks, and clarifying fair use of materials. However, challenges include student perception that free resources are inferior, keeping topics up-to-date, lack of editing and review compared to textbooks, and lack of motivation or incentive for faculty to develop OERs due to limited compensation. Integration of OERs with learning management systems is also limited.
