The Wooz tutor of the North Carolina A&T algebra tutorial dialogue project is a computer program that mediates keyboard-to-keyboard tutoring of algebra problems, with the feature that it can suggest to the tutor canned struc- tures of tutoring goals and canned sentences to insert into the tutoring dialogue. It is designed to facilitate and record a style of tutoring where the tutor and stu- dent collaboratively construct an answer in the form of an equation, a style of- ten attested in natural tutoring of algebra. The algebra tutoring dialogue project collects and analyzes these dialogues with the aim of describing tutoring strate- gies and language with enough rigor that they may be evaluated and incorpo- rated in machine tutoring. By plugging our analyzed dialogues into the com- puter-suggested tutoring component of the W ooz tutor we ca n evaluate the fitness of our dialogue analysis.
