The design of collaboration scripts is a new focus of research within the CSCL community. In order to support the design, communication, analysis, simulation and even execution of collaboration scripts, a general specification language to describe collaboration scripts is needed. In this paper, we analyse the suitability and limitations of IMS LD for(More)
IMS LD is a metalanguage that can be used to specify a pedagogical method as a learning design. A learning design is a formal process model, encoded in XML, which can be played by any IMS LD-aware-player to learners online. In order to make it easy to edit learning designs, LD authoring tools are absolutely needed. Through a review of currently available LD(More)
Learning Design offers the possibility of capturing the process , activities, user organization and resources used in a learning experience. But a wider set of scenarios appear when generic services are considered. Integrating such services in a Unit of Learning is difficult due to the lack of a defined bi-directional protocol for information exchange. In(More)
Problem based learning promotes engagement in meaningful learning and cooperation among students. When applying PBL in distributed groups distance has to be bridged by means of technology. Collaborative virtual environments (CVE) can help to overcome two crucial problems of PBL, if used in a distributed learning situation: Firstly, learners have problems to(More)
IMS LD supports the design of personalized learning by adapting activities and other process elements to personal characteristics. This paper presents a new idea to adjust activities and elements to group characteristics for supporting 'groupalized' or group-adapted learning. This may help to improve effectiveness and efficiency of group-based collaborative(More)
Zusammenfassung: Dieser Beitrag skizziert, wie mit Umgebungen für computerunterstütztes kooperatives Lernen (CSCL) traditionelle Pro-bleme computerunterstützten Lernens überwunden werden können. Es werden Einsatzmöglichkeiten derartiger Lernumgebungen in der Schu-le sowie Anforderungen an die Schule aufgezeigt. Als konkretes Bei-spiel wird die am GMD-IPSI(More)
The theory of situated learning emphasizes the importance of authentic learning contexts and the central role of social interaction. In the light of this theory and based on our previous experience, we propose an approach for the development of context-based virtual learning environments. These are virtual worlds, which the learners themselves can create(More)
Peer assessment is a special form of collaborative learning, in which peer students learn through assessing others " work. Recently, the design of collaboration scripts is a new focus area within the CSCL community. In this paper, we present a method based on open e-learning standards to script peer assessment processes. A standard-compatible tool can help(More)
This paper presents an approach to develop a web-based, multiuser , 3D simulation learning environment supporting virtual communities of practice. This approach emphasizes helping geographically distributed learners to acquire and construct knowledge by doing shared " authentic " activities, to interact with each other as community members, and to perform(More)
