Design an Adaptive Competency-Based Learning Web Service According to IMS-LD Standard

Equal opportunities and the democratization of education, promoted by the establishment of the same content for all learners, can stigmatize and widen the differences and inequalities. Thus, the learner’s heterogeneity is inevitable and often regarded as unmanageable. Thus, customizing the environment to learners improve the learning process quality. There are several adaptation approaches of e-learning environment, such as; adaptive hypermedia system, semantic web, etc. In our proposed service, we adopt the competency based approach (CBA), and we consider that the adaptation relevance depends on the adequacy of the information collected through a personal diagnosis. This diagnostic takes place via an adaptive test using the Item Response Theory (IRT) in a formative perspective without trying to situate the learner in relation to others. This intelligent test, administered items in an appropriate order in a short time and produces relevant results. Thus learning system can lead the learner to gradually acquire a competency taking into account its needs and predispositions. The system will be implemented as an activity in a pedagogical scenario defined responding to the learner’s needs, while aligning with the norms and standards. Thus, some technical choices are required as far as standards and norms are concerned
