This document discusses the pros and cons of open educational resources (OER). It outlines several advantages of OER including flexibility to update materials, the ability to create interactive content, lower costs compared to textbooks, increased portability with mobile devices, and access to knowledge from many contributors. Potential downsides include inaccuracies from open content, inability to change licenses once granted, the time consuming nature of developing OER, lack of face-to-face interaction, and limited awareness of OER programs currently. The document concludes that with research, OER can be an effective way to advance learning globally by increasing access for those unable to access traditional education due to cost or location barriers.
