The document discusses personal learning environments (PLEs) and how individuals can take control of and manage their own learning through various digital tools and online networks. It provides examples of tools for generating content, sharing content, organizing content, and communicating with others. These tools allow learners to connect with other learners, join communities, and participate in online conferences to drive 21st century pedagogy and social learning. PLEs give learners agency over their own educational experience through aggregating and sharing resources across different channels and networks.
