The Reflective Tutorial Dialogue System (ReTuDiS) is a system for learner modelling historical text comprehension through reflective dialogue. The system infers learners' cognitive profiles and constructs their learner models. Based on the learner model the system plans the appropriate--personalized for learners--reflective tutorial dialogue in order to promote their reflection, a fact which leads them towards scientific thought. The system consists of two parts: (1) the Diagnosis part and (2) the Reflective Tutorial Dialogue part. In this paper we present the dialogue strategies, tactics and plans which are used by the dialogue part for the generation of the appropriate for learners' reflective learning dialogues according to their learner models. Moreover, in this paper we present the experts' comments concerning the tutorial dialogue during an experiment. (Contains 3 figures and 6 tables.)
