This document summarizes the pros and cons of open educational resources (OER). The key pros are that OER materials are less expensive for students, allow more flexibility in course design, have no copyright issues, and improve access to quality curriculum for all students. However, the cons are that OER materials may lack quality if not properly refined, rely on a few individuals' enthusiasm which risks them becoming a fad, often lack sustainable funding, and have limited supporting materials compared to publisher options. Overall, OER offers benefits but will require time and institutional support to grow and convince educators of their value.
