The paper presents an investigation about the learner’s cognitive profiles in the context of Tapejara Project¹. In this investigation, we have assumed that the learner’s Cognitive Style of Learning (CSL) actually influences his/her cognitive behavior while performing a long distance Web course. The paper describes the empirical procedures used to generate the learners’ cognitive profiles and his/her associated learning behavior that must be considered in the adaptive Web training environment. The training target population refers to the Telecommunications Company’s employees. The learner’s CSL assessment was obtained from the statistical analysis of the Ross Test data [14]. The CSL learning behavior was obtained from the statistical analysis of the navigational log data in an experimental training module designed for this purpose. The statistical results have shown five CSL groups, their style dimensions and the correlation between each CSL group and their navigational behavior in the Web training module.
