In this paper we investigate the non-verbal behaviour of a tutor and propose a model for ECAs (Embodied Conversational Agents) acting as virtual tutors. We have conducted an empirical study where we focused on the distribution of gaze, head and eyebrowns behaviour of the tutors in a teaching scenario and on the co-occurrences of these behaviours with certain teaching activities or conversational events. Further, we built an ECA with conversational capabilities, episodic memory, emotions and expressive behaviour based on the result from the empirical study.
