Human tutors are not always and everywhere available and that’s why computer based tutoring is developed. So, HCI principles relating to user experience (UX) design and usability testing must be implemented within the ITS development process to improve performance.įace-to-face and one-to-one human tutoring is the best tutoring field. This leads to low performance of the system or the user’s rejections of the software. One of the causes of a software failure is that the software cannot perform according to the user’s needs (e.g., improved learning) or the user is unable to use the system properly. Human-computer interaction (HCI) or usability of Intelligent Tutoring Systems, the primary focus of the current chapter, is an implicit challenge of all software development projects. Simulating a human tutor requires a complex process involving the application of an pedagogical strategy in the outer loop as well as accounting for inner loop factors such as methods of tutoring, understanding of the current state of the student being tutored (accurate student model), and understanding of basic affective measures of the student. The implementation of tutoring within a computer based environment brings challenges such as software system requirements, platform independence, and flexibility of software programming language.

These systems are faced with three main challenges which are system development challenges, implementation of pedagogy, and usability hurdles. Intelligent Tutoring Systems (ITS) are computer software systems that provide automated tutorial help such as feedback and guidance to learners.
