In Socratic tutorial dialogues the tutor selects the most appropriate question to be asked, based on assumptions about what the learner knows. However, there is no guarantee that the learner will understand the question. Indeed, the assumptions of the tutor are sometimes likely to be inaccurate. In this case, an appropriate action for the tutor is to revise its current GOAL as well as its current dialogue plan. In this paper, we present an instance of this issue in PROLOG-TUTOR, a tutoring system for Logic Programming. Our contribution is an explicit address of the dialog management mechanism which supports the revision of the tutor's intention in a Socratic dialogue. This is done using a combination of the theory of accommodation of communicative acts with the notion of revising intentions.
