In this paper, the domain expert system, that a generator of intelligent tutoring systems (ITS) includes with the applications it produces, will be presented. This system, MeT (Methodology Tutor), is responsible for the description and teaching of the procedural domain knowledge (called methodology) of the ITS. The knowledge handled by the system is represented with frames. MeT operates in two modes: during authoring mode, several editors are provided to support the authors in the description of the methodology that will be taught. In tutoring mode, three agents are provided: a guide for the simulation of the methodology evolution, a learn-by-discovery agent that comments on the students' actions and a judge that validates the students' selections. Finally, a part of the procedural knowledge of an example application is presented.
