Developing pedagogically effective tutorial dialogue tactics: experiments and a testbed

Although effective tutorial dialogue strategies are well understood, tutorial tactics that govern brief episodes of tutoring, such as a single step, are not. Because better tactics seem to be crucial for further improving pedagogical effectiveness, we have begun investigating the effects of varying tutorial tactics. In this paper we describe two planned experiments and the testbed we have created to support this experimentation.
