Designing Learning Activity to Be Individualized

The modelling of the learning individualization process is a complex problem which needs multidisciplinary knowledge. The variety of decision problems and of complex domain will never be just one method of model-based decision support. For that making rational decision should be distributed in different levels using various types of knowledge and models. The multi-modelling of the learning activity imply specifying for models of each activity: The didactic model, the knowledge object model, the interface model and the cognitive model given by the actors of design. We propose in this paper a new current of learning activity design based on activity theory where the design of the learning activity means the specification of its specific teaching materials called pedagogical instruments, this material has the mediation role between the leaner and the objects presented in the activity.
