Declarative representation of curricula models: an LTL- and UML-based approach

In this work, we present a constrained-based representation for specifying the goals of “course design”, that we call curricula model, and introduce a graphical language, grounded into Linear Time Logic, to design curricula models which include knowledge of proficiency levels. Based on this representation, we show how model checking techniques can be used to verify that the user’s learning goal is supplied by a curriculum, that a curriculum is compliant to a curricula model, and that competence gaps are avoided. This proposal represents the most recent advancement of a work, carried on in the last years, in which we are investigating the use of both agents and web services for building and validating curricula.We also outline future research directions.
