ICICLE (Interactive Computer Identification and Correction of Language Errors) is a tutoring system under development that instructs deaf users of American Sign Language on written English skills1 . (See (McCoy and Masterman (Michaud) 1997) for a discussion of overall system architecture.) The text generation module it will employ produces original text to instruct the user on errors found in his or her writing, tailored to the user' s understanding and learning style. The model I propose for planning this text composes it according to a four-tier response anatomy. It combines bottom-up and top-down planning approaches and takes into account a detailed representation of user language proficiency and a history of interaction with a user in order to create text that is maximally understandable and informative to the individual.
