Tutors with infinite patience - KATIE HAFNER, New York Times News Service
Fourteen-year-old Rochelle Brown was close to solving an algebra problem. Yet she stumbled repeatedly on one calculation: -2.3 + .5. As she sat at a computer screen, she kept typing 2.8, an incorrect answer. Eventually a hint popped up: "Think about the sign of your answer." When Rochelle finally typed the correct sum, -1.8, the computer showed its appreciation by allowing her to move on to a new problem. She smiled at her small triumph.... Broadly defined, an intelligent tutoring system is educational software containing an artificial intelligence component. The software tracks students' work, tailoring feedback and hints along the way. By collecting information on a particular student's performance, the software can make inferences about strengths and weaknesses, and can suggest additional work.
