The Grace Tutor: A qualified success
The Grace Intelligent Tutoring System is being developed within NYNEX Science & Technology, Inc. to assist in teaching COBOL to both novice and experienced programmers. We describe the result of three trials with Grace and the lessons that we learned by having a wide variety of student populations in real classes. We discuss the changes to the Grace Tutor which create greater congruence between the tutor and the actual programming environments used by the students. Finally we discuss the one aspect in which we do not consider the Grace Tutor a success: our inability to move Grace from the lab into everyday, classroom use. We discuss why we think this critical point has not yet been reached, not only by the Grace Tutor but by numerous other educational technology projects which have been only laboratory successes.
