A three-level model for educational evaluation process in a client/server environment

In this paper, we will prove that the educational evaluation process can be described by a three-level model: the conceptual level, the implementation level and the user level. At the conceptual level, the automata formalism represents in a very formal way the educational process's environment including tests' structure and learner-system interaction. This formalism is implemented in XML to define a new test description language and allows designing an evaluation system running as an automaton. At the user level, we make use of the evaluation system and-produce XML documents in the test description language for questionnaires.
