The CIRCSIM-Tutor version 3 input understander is the module which will process student answers during a tutoring dialogue. We have transcripts of human tutors conducting such dialogues, as well as logs of students using earlier versions of the computer tutor. This paper addresses how the input understander handles some of the language phenomena we have observed. Even when the student is giving short answers to simple questions, the tutor sometimes must handle them as simple student initiatives.
