Collaborative learning and technological environment for evoking interactivity-building of knowledge

The purpose is to support learning activity in an Internet learning space. We examine knowledge management and knowledge representation of the learning information for collaborative learning (CL) support. RAPSODY-EX (REX) is a distributed learning support environment organized as a learning infrastructure. REX can effectively carry out CL support in asynchronous/synchronous learning mode. At the CL, various information in the educational context is referred and reused as knowledge, which a user can practically utilize. We aim at the construction of an increasingly growing digital portfolio database. In addition, the architecture of the learning environment that includes such a database is researched.
