This document discusses professional learning networks (PLNs), which allow individuals to connect with others to facilitate learning. A PLN can be formed using social media and tools like Twitter, blogs, and RSS feeds to collaborate with others, ask questions, and stay updated with new information from one's network. PLNs benefit learning by enabling access to resources beyond one's local area and providing support from a community of practitioners. Maintaining a PLN involves using online tools and platforms to actively engage with your network and share your own knowledge.
