This article discusses the theory of learner’s psycho-pedagogical criteria in the adaptation of a hypermedia educational system. To measure learning preferences, several adaptive systems are based on taking into account individual differences, in particular, the "thinking style". This concept refers to a set of pipes and strategies in how to manage and organize information. However, these systems face several challenges, rising important questions, such as: The styles used in the training context, among the multitude of styles defined in the literature? How to identify such styles? The proposed approach is based on measuring the learner performance, where the learning objective is designed respecting on the features offered by the HBDI (Herrmann Brain Dominance Instrument model) model to infer the learner style of thought. If the learner's performance is satisfactory, then it is likely that the content and teaching strategy proposed matches his style. Otherwise, the course design is to be adapted based on the tracks and paths of the learner.
