Over the last decade, Adaptive hypermedia (AH) have been under development [8], and particularly in education [3], [9], where learners have access to personalized resources1 according to their knowledge, preferences and goals. In this paper, we present only the the typology of our elementary adaptation patterns, while the whole process of defining adaptation strategies for the adaptive navigation is described in [10]. The paper is organized as follows. In section 2, we define the notion of elementary adaptation patterns that we propose. Afterwhat, in section 3 we present the syntax of the elementary adaptation patterns and followed in section 4 by the description of the associated semantic. In section 5, we detail the typology of the elementary adaptation patterns. Finally, in section 6 we conclude the paper.
