STELLAR views learning as intimately connected with social interaction between people and as the continual construction of knowledge. New digital tools connect learners with other learners and teachers, trainers, experts or more knowledgeable others, helping them to communicate in effective ways, both to share and build knowledge. A wide variety of information and communication technologies (ICTs) connect people including web-based applications such as open and closed forums, personal or shared blogs, chat rooms, instant messaging and video conferences, tagging and collaborative text editing systems.
