It addresses the question, "what can a computer do for a group of learners beyond helping them share information?" CLARE differs from virtual classrooms and hypermedia systems in three ways. First, CLARE is grounded on the theory of meaningful learning, which focuses the role of meta-knowledge in human learning. Instead of merely allowing learners to share information, CLARE provides an explicit meta-cognitive framework, called RESRA, to help learners interpret information and build knowledge. Second, CLARE defines a new group process, called SECAI, that guides learners to systematically analyze, relate, and discuss scientific text through a set of structured steps: summarization, evaluation, comparison, argumentation, and integration. Third, CLARE provides a fine-grained, non-obtrusive instrumentation mechanism that keeps track of the usage process of its users. Such data forms an important source of feedback for enhancing the system and a basis for rigorously studying collaboration learning behaviors of CLARE users. |
