Research in individual differences and in particular, learning and cognitive style, has become a basis to consider learner preferences in a Web-based educational context. How learnerpsilas learning style influences his/her navigation behavior has been investigated by several studies, which indicate that we can deduce the learning style from the navigation behavior. In this paper, we propose an indicator of ldquonavigation typologyrdquo. We detail the way in which this indicator is calculated, based on tracks analysis, which are aggregated into low and intermediate level indicators to determine the value of the navigation typology.
