ABSTRACT

Many applications accessible through the web suffer from a noticeable lack of support in adapting the information presentation to users. The way users learn differs from an individual to an other, if not for the same individual from an application to an other one. These individual differences affect the learning style of users. They are classified into 3 categories which are: affective, cognitive and physiologic styles. There is little research to examine how to design adaptive systems based on user’s cognitive styles. In this paper, we are focusing on user cognitive styles definition and suggest a technique in the design of an adaptive hypermedia system. We investigate the selection of the output modality that best tailor the user profile.

In section 1 we introduce the problematic of learning from net-structured knowledge then we define the cognitive styles. In section 2, we present the main cognitive styles which are the most mentioned in literature. The taxonomy of these cognitive styles and techniques to assess them are detailed in section3. In the last section, we present the structure of our site and model. We investigate the relationship between the cognitive style and the filtering process of the outcome modalities. For the development of the system, we have chosen the two technologies: XML and ASP.
