The pace of technological change has challenged historical notions of what counts as knowledge. Dave Cormier describes an alternative to the traditional notion of knowledge. In place of the expert-centered pedagogical planning and publishing cycle, Cormier suggests a rhizomatic model of learning. In the rhizomatic model, knowledge is negotiated, and the learning experience is a social as well as a personal knowledge creation process with mutable goals and constantly negotiated premises. The rhizome metaphor, which represents a critical leap in coping with the loss of a canon against which to compare, judge, and value knowledge, may be particularly apt as a model for disciplines on the bleeding edge where the canon is fluid and knowledge is a moving target.
