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)
A common problem of CSCL (Computer-Supported Cooperative Learning) is addressed: How can we coordinate goal-directed, effective interaction in a group of learners? We introduce the concept of learning protocols which originates in script theory. We then discuss which dimensions of cooperative learning can be supported by learning protocols and propose how(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)
We discuss an integrative design for computer supported cooperative learning (CSCL) environments. Three common problems of CSCL are addressed: How to achieve social orientation and group awareness, how to coordinate goal-directed interaction, and how to construct a shared knowledge base. With respect to each problem, we propose a guiding metaphor which(More)
In this paper we describe our approach for supporting the use of the problem-based learning (PBL) method in virtual learning environments. We identify two key difficulties. Firstly, neither learners nor tutors, who are used to more traditional methods of teaching, know exactly what to expect from PBL or how to behave appropriately within their new roles.(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)
