This document discusses the pros and cons of open educational resources (OERs). It notes that while OERs improve access to educational materials, their quality is not always guaranteed and instructors must carefully review content. OERs can be misunderstood as providing official degrees. However, they offer minimal or no costs and allow peer review and sharing of best practices worldwide. While OERs increase accessibility, reliable internet access remains a challenge in some areas. Licensing terms can confuse users and intellectual property issues are a concern, though OERs reach wider audiences. Future challenges include ensuring the sustainability of OER sites and conducting more research on learning outcomes.
