The aim of this article is to propose to a teacher a framework to evaluate and revise his courses by following the students during the learning phase. We asume that the teacher doesn't use an educational platform and have resources at his disposal. We model the course by using a global ontology (an overall view of the system) with limited educational resources. We then link these resources to the various concepts contained in the global ontology. In order to follow the students' improvements, we analyse from the servers' logs and we categorize student in groups. We then propose to the teacher and the webmaster two types of revision in order to improve learning.
