The task of generating personalized learning scenarios, in an automatic fashion, for learners is a complicated task. The difficulty is compounded when these scenarios are to be integrated within a serious game dedicated to people with disabilities. In this case, the specificities of the learner’s preferences and competencies should also be taken into account in addition to the learning domain and the serious game specificities. Building on our previous work, we present in this paper the platform GOALS. This platform allows educational designers to generate learning scenarios for learners, manage learning domain and serious game knowledge, as well as, the learners’ profiles. We also present two evaluations in the context of project CLES (Cognitive Linguistic Elements Stimulations). The objectives of these evaluations are to verify the functionality of GOALS, to verify the project CLES’s knowledge and to study the impact of the generated scenarios on the learning of real-world learners.
