An agent-based collaborative learning system

The paper presents a collaborative on-line learning system for open and distance learning that tries to respond to the requirements of an efficient and motivating learning process. The system comprises several learning modes that try to combine the traditional style of teaching with "problem-based" learning: learning by being told, problem-centred demonstrations, problem analysis, and assessment of acquired knowledge. A fifth mode, creative problem solving, as an essential part of the learner-centred approach, will be supported by future versions of the system. Cooperative teaming is achieved either between the student and the tutor or inside a group of learners interacting or not with the human tutor. Student interactions with the system may be either synchronous or asynchronous. The system is a CSCW environment enhanced with artificial agents that represent an active part in the learning process. It includes personal agents to assist the students and the human tutor, an artificial tutor that tries to partially replace the human one during student interactions with the system, and an information agent to search relevant information.
