This tutorial deals with the broad class of intelligent learning systems for cognitive skills development. These systems have proved very effective, especially within the applied domains where learning is more concerned with the operational knowledge. These systems can accommodate both the 'instruction' and 'construction' of knowledge and involve active engagement, they have been more successful as demonstrated by the popularity and wide acceptance of simulation based learning systems. This tutorial aims to provide the intelligent systems developer and implementer community with the knowledge that they need in order to make informed assessments and decisions about such systems. It considers in turn five questions that can be asked about any intelligent learning systems for cognitive skills development: 1. What are the various aspects of learning facilitated by such systems? 2. What are the theoretical issues that underlie development of such systems? 3. What functions are served by intelligence and how they are twinned with assessment issues? 4. What pedagogical issues are important in the development of such systems? 5. How one can go about practically developing such systems?
