IWT: an innovative solution for AGS e-learning model

This paper is a technological development and realisation of the e-learning model presented by Albano G., Gaeta M. and Salerno S. (AGS) which appeared in the previous issue of IJKL, focused on the advanced features provided by Intelligent Web Teacher (IWT) an innovative learning platform available in the market. In this paper, the approaches used in IWT for knowledge representation and management through ontologies are examined in detail. Similarly, the way the special component Learner Intelligent Advisor (LIA) uses these and other information available on the system for creating personalised learning paths taking into account the single user preferences including present knowledge state and preferred didactic approach, etc. is carefully studied. IWT is in continuing evolution. In particular, we are improving LIA structure and algorithm and integrating IMS learning design for the description of our unit of learning. We paid particular attention to the issue of giving an insight into the main ideas and challenges underlying the solutions we chose.
