Heuristic Evaluation of Web-Based Intelligent Tutoring Systems

Intelligent Tutoring Systems (ITSs) might improve learning and teaching in two distinct ways. Just as they have made teachers and students more productive, they could reduce teaching costs or increase the speed with which learners acquire knowledge/of knowledge acquirement. Alternatively, such systems might help improve the quality of learning, rather than simply making it faster and cheaper. In this paper we first review evidence that heuristic evaluation can improve the efficiency of Web-based Intelligent Tutoring Systems; then we consider how they might lead to better educational outcomes
