In this paper we explore the utility of the Navigation Map (NM), a graphical repre- sentation of the discourse structure. We run a user study to investigate if users perceive the NM as helpful in a tutoring spoken dia- logue system. From the users’ perspective, our results show that the NM presence al- lows them to better identify and follow the tutoring plan and to better integrate the in- struction. It was also easier for users to concentrate and to learn from the system if the NM was present. Our preliminary analysis on objective metrics further strengthens these findings.
