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)
Knowledge that needs to be learned in the workplace may often be illstructured, arising from the need to solve a problem, rather than from a motivation to learn an entire content domain. Existing visually structured knowledge representation methods for education are designed to support subject-based learning. In this paper we describe our conceptual model(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)
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)
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)
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)
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)
This paper argues that environments for computersupported cooperative/collaborative learning (CSCL) can overcome the shortcomings of traditional approaches to computer-based learning. We discuss how such systems can be used in schools and what specific requirements exist. As a concrete example we present VITAL, a virtual cooperative learning environment(More)
In this paper, we propose a new technical approach to support new forms of e-assessment. This approach is based on international e-learning standards and a service-oriented approach. Through a combined use of IMS LD and IMS QTI, new forms of assessment can be modelled as a unit of assessment, a specific unit of learning with a set of QTI documents or/and(More)
