FORMATIVE ADAPTIVE TESTING SERVICE WEB TO INDIVIDUALIZE ELEARNING PROCESS

摘要

In most of the existing E-learning systems, the content and the order of activities are presented in a static manner without taking into consideration the learners characteristics. Therefore, customizing and adapting the environment to the learners profile has shown important improvement in education quality. There are several adaptation approaches of E-learning environments, such as, adaptive hypermedia system, semantic web, etc. In our proposed system (RIMEV), we adopted a Competency Based Approach (CBA), and we found that a well adapted system depends mainly on the adequacy of the information collected through a personal diagnostic. This diagnostic takes place via an adaptive test using the Item Response Theory (IRT) in a formative approach. This Intelligent test administers optimal items in an appropriate order in a short time and produces a good assessment of the learners skills with accurate results. Thus the e-learning systems can lead the learner to gradually acquire a skill by taking into account his/her characteristics and predispositions. Concerning the technological aspect, the system is implemented as a composed web service, which calls several basic services that coordinate according to an orchestration plan. This allows interoperability with heterogeneous learning systems.
