Intelligent Tutorials Systems have demonstrated their effectiveness in various applications of the teaching-learning processes. However; its construction involves a complex and intense work of knowledge engineering, which prevents a more general use and optimal use. In this work provides a model that integrates the knowledge-based systems, the Conceptual Maps and Intelligent Tutorials Systems that favors the design of these systems, taking into account the facilities and naturalness of the Conceptual Maps. The proposed model is the basis for the design and implementation of HEMCI computational tool, which is under development, and promotes the development of Intelligent Tutoring Systems to computer non-expert users. Finally, an example of the model described for the teaching-learning process of the basic theory of combinational logic approach.
