Sean Dowling presented on using technology-enhanced personal learning environments (PLEs) to support mobile learning. Some key points:
1. Lifelong learning involves both formal and informal learning throughout one's life to improve knowledge and skills. Informal learning occurs through everyday experiences and is often mobile in nature.
2. Learning trajectories can be disrupted when learners are mobile due to competing demands, limited access to existing knowledge, and poor recall of original experiences.
3. PLEs, consisting of customized web-based tools, services, and resources, can help address these challenges by allowing learners to record experiences for later reflection, access recommendations and collaborations, and receive notifications.
