The document discusses personal learning environments (PLEs) and personal learning networks (PLNs). It describes how PLEs are based on Web 2.0 and social software, and allow individuals to organize their own learning. PLNs help with recognizing informal learning and finding resources. As technology advances, online learning has grown significantly with developments like open source applications, increased access, and the idea of the PLE for individually managing one's learning. Some students transition from building their PLE to establishing a professional learning network (PfLN) that overlaps their personal and professional interests for lifelong competency development and knowledge sharing.
