This document defines personal learning environments (PLEs) as an approach to learning directed by one's own needs and interests, facilitated by a collection of tools. PLEs allow learners to draw connections from various resources they select and organize. The document suggests implementing PLEs in classrooms by setting expectations, providing guidance on topics and technology options, communicating assessment, and providing examples. PLEs encourage learning beyond the classroom by creating a continuous space for learners to engage in communities of practice and learn from multiple people and places.
