Abstract: In Computing Environment for Human Learning (CEHL), it is more difficult for a tutorto know which learners are participating and which need help. Learners may not participate formany reasons. Sometimes a learner may need encouragement; he may encounter technical or otherdifficulty. When analysis can help, it also allows for timely action to remedy blocking situations. Inthis article, we propose a learner modeling approach. This modeling process gathers a set of treatments allowing elaborating and updating relevant information about the learner (personaldata, learner's characteristics, learning state, interactions between the environment and the learner,and the learner's knowledge, etc.) from the data collected in the course. This information is basedon the analysis of the learner's behavior.
