Resumen
In this paper, we discuss the issue of adaptativity in mobile learning. To adapt a system, we need a learner model. We discuss the limits of learner model in the environment of mobility. We present LIP (Learner Information Package) and we propose an extension of LIP (C-LIP) in order to take into consideration new dimensions induced by mobility. To test this extension, we conceive and develop a prototype of an editor aiming at assisting the teacher in the implementation and in the update of C-Lip.
