英文原文 Extending the Limits of CVE s to Support Collaborative e-Learning Scenarios Abstract This paper proposes the use of collaborative virtual environments in order toprov ide collaborative e-learning services in an efficient and cost effective way. On the one hand, we present the transformation of well known collaborative learning techniques t o collaborative elearning scenarios. The collaborative learning techniques, which are discussed in this paper, are brainstorming/roundtable, think pair share, jigsaw, quick writes/microthemes, and structured academic controversies. On the other hand, we des cribe the necessary modifications of the collaborative virtual environments in order to support collaborative e-learning services and scenarios. Main proposals are the integra tion of more media to offer more awareness, the support of more people with different roles, and the definition of an integrated system architecture. 1、Introduction It is well known that collaborative e-learning is a definite need nowadays. Much research and technological work has been done in order to support and/or to offer elea rning services. In the technological field there are technologies, commercial tools, and /or research prototypes to support e-learning [1], [3]. Theoretical frameworks and lear ning techniques have been presented for collaborative learning. Furthermore it is more difficult for both learners to learn and teachers to teach from distance. Thus, in order to provide collaborative elearning services to the users in an effective way, it is neede d to incorporate available or new technologies with learning theories and the user nee ds. Starting from the user requirements, we have realised that the main users need is to be more aware about the actions of the rest of users in the collaborative e-learning groups. Systems,which satisfy this need and integrate the necessary tools for realising the collaborative e-learning techniques, have many possibilities to succeed. Furtherm ore, a
