Continuous innovation and evolution of the intelligent tutoring system TEx-Sys

The structures and functionalities of all developed and implemented intelligent tutoring systems based on the very first TEx-Sys model are presented, and their continuous innovation and evolution are shown. The TEx-Sys is based on the cybernetic model of educational system, which is based on Gordon Pask's statement that teaching is control of learning. The knowledge has a contextual component and creation and design of knowledge bases is emphasised as particularly important. The testing of prototypes has been carried out with students of different ages, from primary education to university level. Based on our experience of designing and implementing intelligent tutoring tools a possible extension of our approach using intelligent tutoring applets is considered.
