An Approach to Usability Evaluation of an Intelligent Tutoring System

Intelligent tutoring systems are a generation of computerized educational systems, which are intended to improve the process of learning and teaching by attempting to mimic the capabilities of human teachers. The development of application technology in the field of computerized educational systems has not been accompanied by an adequate usable, user-centered interface design, possibly resulting in scarce, unusable support for interaction and indeed in the decrease of interface’s effectiveness and efficiency. In order to improve the usability of an intelligent tutoring system, nowadays perhaps the most important goal of current research in the field of human-computer interaction in general, scenario-based usability evaluation is advocated as a formal approach for intelligent tutoring system evaluation. Key-Words: intelligent tutoring, intelligent tutoring systems, scenario-based usability evaluation
