The learning system that makes use of Web 2.0 constitutes a social constructivist theory of learning. This model stresses collaboration, arguing that knowledge and learning are actively constructed via social relationships and interactions—precisely what a learning system employing Web 2.0 tools encourages, with all the ways in which it stimulates thinking outside the classroom, stirring up new ideas and spawning new discussions.
This learning system becomes more relevant with each succeeding generation, esp. the current “Google generation,” used to free, asynchronous, and instant ways of garnering information in various forms and on endless topics, in a generally non-authoritative manner.
Not only as a learning system but also as a general tool, social software has an immense power to jump-start and deepen networks of professionals and learners.
