This document discusses the pros and cons of open educational resources (OER). It outlines several advantages of OER including flexibility to update materials, potential for interactivity, lower cost compared to textbooks, portability, and access to knowledge from many contributors. Potential downsides include reliability issues if content is inaccurate, restrictive nature if authors later change permissions, time required to develop high-quality OER programs, lack of face-to-face interaction, and limited awareness of OER currently. Overall, the document concludes that with research, OER have potential to advance learning for those with financial or geographic barriers to education.
