Peer learning and open educational resources (OER) can be effective tools for learning, as discussed in the document. Peer learning works best in small group settings where students can engage with each other's ideas and provide feedback. While open online content enables sharing of resources across institutions, ensuring meaningful human interaction remains important for community building and hybrid online/in-person learning experiences. The document explores using tools like Zoom and open online courses to facilitate web-based peer learning and generation of communities of learners.
