Model Tracing – A Diagnostic Technique in Intelligent Tutoring Systems

An educational system is a community where students and teachers are involved in a process of learning and teaching. Intelligent tutoring systems (ITS) are computer systems designed for support and improvement of learning and teaching process in freely chosen domain knowledge. Tutor–Expert System (TEx-Sys) is a hypermedial authoring shell for building intelligent tutoring systems. While testing a student, human tutor observes sequence of student actions, remembers a number and type of student mistakes and number of additional questions or other type of help used to push student forward. Human tutor makes evaluation of student knowledge that is based on gathered information. Those is why ITS that considers only final results, that is, student answer, cannot justly and completely evaluate student knowledge. For that reason we have decided to introduce a model tracing – a diagnostic technique to be used in student modelling in TEx-Sys. The TEx-Sys provides help and remediation for future work that is based on conciderationing of number of misconceptions.
