This work takes place in the framework of the realization of a pedagogical assistance system in the domain of technology enhanced learning (TEL) .In this context, we defend the thesis that it is possible to integrate an interface with a pedagogical agent in an ILE (interactive learning environment) based on web service, which aims to provide pedagogical assistance adapted to the learner. our approach is based on the analysis of the course of the learner , the system allows to represent , assist and analyze the evolution of a learning situation in order to detect the assistance status (blocking learner , non completing tasks…etc.) it is based on the comparison between the actions of the learning (traces) and action to perform (the domain model ) the traces provide knowledge about the learning situation with one of the web 2.0 reporting techniques .Our approach is to provide a learning system that incorporates a proactive assistant agent, able to offer a range of services (activity monitoring, progress monitoring, guidance and assistance during the course) to learners in an intelligent manner. In addition, this agent has a learning mechanism to enable it the adaptation to new situations ensuring automatic and continuous assistance to the learner. The system adopts a recent pedagogical and didactical approach, based on constructivist approach which implies a maximum cognitive activity of the learner. And also , our approach focuses on the representation of the evolution of learning situations and on adaptive pedagogical agent that offers several types of pedagogical assistance.the role of pedagogical and technique accompanist.
